to silc-devel mailing list or appear on 'silc' channel on SILCNet.
-General
-=======
-
- o Create apps/tutorial containing various Toolkit API tutorials.
-
- o The Toolkit split. The Toolkit is to be splitted in parts. How many
- parts and what the parts are isn't decided yet. Each part is a separate
- software package. Current thinking is of the following:
-
- SILC Toolkit SILC protocol, client and server library
- SILC Runtime Toolkit runtime library
- SILC Crypto Toolkit crypto, asn1, math, skr, pgp, etc.
-
- The rationale for this is of course that other than SILC projects
- might like to use the various libraries SILC Toolkit provides, but
- naturally they don't want the bloat of SILC protocol related stuff.
-
- The Runtime library in SILC Toolkit is a general purpose runtime library,
- like Glib and APR are. The runtime library is to be developed further
- to provide alternative to Glib and APR.
-
- The Crypto library in SILC Toolkit is a general purpose crypto library
- providing pretty nice APIs compared to many other crypto libraries,
- especially OpenSSL. The Crypto library is to be developed further
- to include support for OpenPGP, X.509 and SSH2.
-
-
-lib/silccore
-============
-
- o SILC_PACKET_FLAG_ACK support. Implement ACK packet and packet payload
- to silcpacket.c.
-
- o All payload encoding routines should take SilcStack as argument.
-
- o Remove SilcCommandCb from silccommand.h.
-
- o All payload test routines into lib/silccore/tests/.
-
-
-lib/silcclient, The Client Library
-==================================
-
- o UDP SILC connection support to SILC server
-
- o Giving WHOIS for nick that doesn't exist should remove any same
- named entries from the client cache.
-
- o peer-to-peer private messages
-
- o Private message key request notification to application. See XXX in
- client_prvmsg.c.
-
- o in JOIN notify handle resolving that timedout. Currently the user is
- never joined the channel if this happens. What to do if message is
- received from user that hasn't been resolved/joined?
-
- o Add the SilcStream (socket stream) from the SilcPacketStream and
- SilcSocket from the socket stream to SilcClientConnection for easier
- access to them for programmers. Currently these have to be digged up
- from the packet stream.
-
- o Connection option that attemps to connect to remot host with various
- different mechanisms: UDP 706, TCP 706, TCP 80, TCP 443, UDP 7706 and
- TCP 7706. This is the so called hole punching mechanism.
-
- o Message ACKing support.
-
- o in /cmode and /cumode with +r, maybe the public key and private key
- could be just some "string", which would then match to "string.pub" and
- "string.prv".
-
- o If the SILC Events (see below) are implemented, perhaps client library
- should provide events so that application developer has a choice of
- developing the SILC app with callbacks or with events.
-
- o Ability to recover from rekey errors, at least try to.
-
-
-Runtime library, lib/silcutil/
+Crypto Library, lib/silccrypt/
==============================
- o Fix universal time decoding (doesn't accept all formats) in silctime.c.
-
- o Add functions to manipulate environment variables. (***DONE)
-
- o Add functions to loading shared/dynamic object symbols (replaces the
- SIM library (lib/silcsim) and introduces generic library). Add this
- to lib/silcutil/silcdll.[ch]. (***TESTING NEEDED WIN32, TODO Symbian)
-
- o Add directory opening/traversing functions
-
- o silc_getopt routines
-
- o Add silc_stream_get_root and add get_root stream operation. It
- returns the root of the stream or NULL if stream doesn't have root.
-
- o Change some stream routines (like socket stream API) to accept ANY
- stream and use silc_stream_get_root to get the socket stream from the
- given stream. This will make various stream APIs more easier to use
- when user doesn't have to dig up the correct stream.
-
- o The SILC Event signals. Asynchronous events that can be created,
- connected to and signalled. Either own event routines or glued into
- SilcSchedule:
-
- SilcTask silc_schedule_task_add_event(SilcSchedule schedule,
- const char *event, ...);
- SilcBool silc_schedule_event_connect(SilcSchedule schedule,
- const char *event,
- SilcTaskCallback event_callback,
- void *context);
- SilcBool silc_schedule_event_signal(SilcSchedule schedule,
- const char *event, ...);
-
- Example:
- silc_schedule_task_add_event(schedule, "connected",
- SILC_PARAM_UI32_INT,
- SILC_PARAM_BUFFER,
- SILC_PARAM_END);
- silc_schedule_event_connect(schedule, "connected", connected_cb, ctx);
- silc_schedule_event_signal(schedule, "connected", integer, buf,
- SILC_PARAM_END);
- SILC_TASK_CALLBACK(connected_cb)
- {
- FooCtx ctx = context;
- va_list args;
- SilcUInt32 integer;
- SilcBuffer buf;
-
- va_start(args, context);
- integer = va_arg(args, SilcUInt32);
- buf = va_arg(args, SilcBuffer);
- va_end(args);
- ...
- }
-
- Problems: Events would be SilcSchedule specific, and would not work on
- multi-thread/multi-scheduler system. The events should be copyable
- between schedulers. Another problem is the signal delivery. Do we
- deliver them synchronously possibly from any thread to any other thread
- or do we deliver them through the target schedulers. If we use the
- schedulers then signalling would be asynchronous (data must be
- duplicated and later freed) which is not very nice.
-
- o If the event signals are added, the SILC_PARAM_* stuff needs to be
- moved from silcbuffmt.h to silctypes.h or something similar.
-
- o In case the SILC Events are done we shall create a new concept of
- parent and child SilcSchedule's. When new SilcSchedule is created a
- parent can be associated to it. This association could be done either
- directly by the parent or by any other children. This way the signals
- would in effect be global and would reach all children schedulers.
-
- This relationship would be associative only. The schedulers are still
- independent and run independently from each other. All schedulers
- would be linked and could be accessed from any of the schedulers.
- It should be possible to retrieve the parent and enumerate all children
- from any of the schedulers.
-
- SilcSchedule silc_schedule_init(int max_tasks, void *app_context,
- SilcSchedule parent);
- SilcSchedule silc_schedule_get_parent(SilcSchedule schedule);
-
- o Additional scheduler changes: optimize silc_schedule_wakeup. Wakeup
- only if the scheduler is actually waiting something. If it is
- delivering tasks wakeup is not needed.
-
- o Structured log messages to Log API. Allows machine readable log
- messages. Would allow sending of any kind of data in a log message.
-
- o Base64 to an own API (***DONE)
-
- o Timer API (***DONE)
-
- o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
- SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
- in separately.
-
- o silc_stringprep to non-allocating version.
-
- o silc_hash_table_replace -> silc_hash_table_set. Retain support for
- silc_hash_table_replace as macro. (***DONE)
-
- o SilcStack aware SilcHashTable. (***DONE)
-
- o SilcStack aware SilcDList. (***DONE)
-
- o Thread pool API. Add this to lib/silcutil/silcthread.[ch]. (***DONE)
-
- o Fast mutex implementation. Fast rwlock implementation. Mutex and
- rwlock implementation using atomic operations.
-
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Zip API must be
- defined.
-
- o Add new functions to SilcStack API in lib/silcutil/silcstack.[ch]. Add
- silc_stack_[set|get]_alignment. It defines the default alignment used
- when allocating memory from stack. It can be used to specify special
- alignments too when needed (such as for hardware devices like crypto
- accelerators). Move also the low level silc_stack_malloc and
- silc_stack_realloc from silcstack_i.h to silcstack.h. Remove the
- _ua unaligned memory allocation routines. Remove unaligned memory
- allocation possibility. (***DONE)
-
- o silc_stack_alloc shouldn't require multiple by 8 size argument, it
- should figure it out itself.
-
- o silc_malloc et. al. to respect --with-alignment.
-
- o Add '%@' format to silc_snprintf functions. It marks for external
- rendering function of following type:
-
- /* Snprintf rendering function. The `data' is rendered into a string
- and allocated string is returned. If NULL is returned the
- rendering is skipped and ignored. If the returned string does
- not fit to the destination buffer it may be truncated. */
- typedef char *(*SilcSnprintfRender)(void *data);
-
- It can work like following:
-
- char *id_renderer(void *data)
- {
- char tmp[32];
- id_to_str(tmp, sizeof(tmp), (SilcID *)data);
- return strdup(tmp);
- }
-
- silc_snprintf(buf, sizeof(buf), "Client ID %@", id_renderer, client_id);
- (***DONE)
-
- o Change silc_gettimeofday on Unix to use clock_gettime with REALTIME
- clock if it is available, otherwise use gettimeofday(). (***DONE)
-
- (o SilcIpAddr abstraction. Ipv4 and Ipv6 support to the abstaction.)
- maybe
-
- (o Generic SilcStatus or SilcResult that includes all possible status and
- error conditions, including those of SILC protocol. Though, the SILC
- protocol related status (currently in silcstatus.h) cannot be in
- runtime library) maybe
-
- (o SILC specific socket creation/closing routines to silcnet.h, wrappers
- to all send(), recv(), sendto() etc. Bad thing is that we'd have to
- define all socket options, sockaddrs, etc.) maybe
-
- (o mmap) maybe
+ o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h, and
+ possibly to silcpkcs.h.
+ /* Return fingerprint of the `public_key'. Returns also the algorithm
+ that has been used to make the fingerprint. */
+ const unsigned char *
+ silc_pkcs_get_fingerprint(SilcPublicKey public_key,
+ const char **hash_algorithm,
+ SilcUInt32 *fingerprint_len);
-lib/silcutil/symbian/
-=====================
+ o Add CMAC and maybe others. Change needs rewrite of the internals of
+ the SILC Mac API, currently it's suitable only for HMACs.
- o Something needs to be thought to the logging globals as well,
- like silc_debug etc. They won't work on EPOC. Perhaps logging
- and debugging is to be disabled on EPOC. The logging currently works
- by it cannot be controlled, same with debugging.
+ o Global RNG must be changed to use SILC Global API.
+ o Global cipher, hash, mac, and pkcs tables must use SILC Global API.
-SFTP Library, lib/silcsftp/
-===========================
+ o Add FIPS compliant RNG.
- o Read prefetch (read-ahead, reading ahead of time). Maybe if this can
- be done easily.
+ o Implement the defined SilcDH API. The definition is in
+ lib/silccrypt/silcdh.h. Make sure it is asynchronous so that it can
+ be accelerated. Also take into account that it could use elliptic
+ curves.
+ o Add Elgamal.
-SKR Library, lib/silcskr/
-=========================
+ o Add ECDSA support.
- o Add fingerprint as search constraint.
+ o Add ECDH support.
- o Add OpenPGP support. Adding, removing, fetching PGP keys. (Keyring
- support?)
+ o Add PKCS#1 RSAES-OAEP and RSASSA-PSS.
- o Add support for importing public keys from a directory and/or from a
- file. Add support for exporting the repository (different formats for
- different key types?).
+ o Add GCM mode.
- o Change the entire silc_skr_find API. Remove SilcSKRFind and just simply
- add the find constraints as variable argument list to silc_skr_find, eg:
+ o Do GCC vs ICC benchmarks of all key algorithms.
- silc_skr_find(skr, schedule, callback, context,
- SILC_SKR_FIND_PUBLIC_KEY, public_key,
- SILC_SKR_FIND_COUNTRY, "FI",
- SILC_SKR_FIND_USAGE, SILC_SKR_USAGE_AUTH,
- SILC_SKR_FIND_END);
+ o Add DSA support to SILC public key.
- NULL argument would be ignored and skipped.
+ o The asynchronous functions to perhaps to _async to preserve backwards
+ compatibility with synchronous versions, and make easier to migrate
+ from 1.1 to 1.2. (***DONE)
- o Add OR logical rule in addition of the current default AND, eg:
+ o AES CBC is missing proper alignment code. (***DONE)
- // Found key(s) MUST have this public key AND this country.
- silc_skr_find(skr, schedule, callback, context,
- SILC_SKR_FIND_RULE_AND,
- SILC_SKR_FIND_PUBLIC_KEY, public_key,
- SILC_SKR_FIND_COUNTRY, "FI",
- SILC_SKR_FIND_END);
+ o silc_pkcs_public_key_alloc should accept also SILC_PKCS_ANY as argument
+ and try all supported PKCS until one succeeds. (***DONE)
- // Found key(s) MUST have this public key OR this key context
- silc_skr_find(skr, schedule, callback, context,
- SILC_SKR_FIND_RULE_OR,
- SILC_SKR_FIND_PUBLIC_KEY, public_key,
- SILC_SKR_FIND_CONTEXT, key_context,
- SILC_SKR_FIND_END);
+ o Associate a default hash function with all PKCS algorithms. User can
+ override it in silc_pkcs_sign. DSA with FIPS186-3 determines the
+ hash algorithm by the key length. (***DONE)
- o SilcStack to SKR API.
+ o Document all cipher names, hash names, mac names, pkcs names. (***DONE)
+ o SilcHmac must be replaced with generic SilcMac so that we can add
+ others than just HMAC algorithms. Backwards support (via #define's)
+ must be preserved. (***DONE)
-Crypto Library, lib/silccrypt/
-==============================
+ o Change the DSA implementation to support FIPS186-3. This means that
+ the q length is determined by the key length. (***DONE)
o Add silc_crypto_init and silc_crypto_uninit. The _init should take
SilcStack that will act as global memory pool for all of crypto
preference over the default once, ie. user can always dictate the
order of algorithms. (***DONE)
- o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h, and
- possibly to silcpkcs.h.
-
- /* Return fingerprint of the `public_key'. Returns also the algorithm
- that has been used to make the fingerprint. */
- const unsigned char *
- silc_pkcs_get_fingerprint(SilcPublicKey public_key,
- const char **hash_algorithm,
- SilcUInt32 *fingerprint_len);
-
o Change SILC PKCS API to asynchronous, so that accelerators can be used.
All PKCS routines should now take callbacks as argument and they should
be delivered to SilcPKCSObject and SilcPKCSAlgorithm too. (***DONE)
check the alg->hash, supported hash functions. Maybe deliver it also
to all other functions in SilcPKCSAlgorithm to be consistent. (***DONE)
- o Add DSA support to SILC public key.
-
o Add DSS support. (***DONE)
- o Implement the defined SilcDH API. The definition is in
- lib/silccrypt/silcdh.h. Make sure it is asynchronous so that it can
- be accelerated. Also take into account that it could use elliptic
- curves.
+ o All cipher, hash, hmac etc. allocation routines should take their name
+ in as const char * not const unsigned char *. (***DONE)
- o Add ECDSA support.
- o Add ECDH support.
+SKR Library, lib/silcskr/
+=========================
- o AES CBC is missing proper alignment code (see silc_1_1_branch).
+ o Add fingerprint as search constraint.
- o All cipher, hash, hmac etc. allocation routines should take their name
- in as const char * not const unsigned char *. (***DONE)
+ o Add SSH support. (***DONE, TESTING NEEDED)
+ o Add OpenPGP support. Adding, removing, fetching PGP keys. (Keyring
+ support?)
-SILC Accelerator Library
-========================
+ o Add support for importing public keys from a directory and/or from a
+ file. Add support for exporting the repository (different formats for
+ different key types?).
- o SILC Accelerator API. Provides generic way to use different kind of
- accelerators. Basically implements SILC PKCS API so that SilcPublicKey
- and SilcPrivateKey can be used but they call the accelerators.
- (***DONE)
+ o Add find rule AND and OR. The default is always AND. Add
+ silc_skr_find_set_rule.
- o Implement software accelerator. It is a thread pool system where the
- public key and private key operations are executed in threads.
- (***DONE)
+ o Add silc_skr_find_add_search_file that can be used to add a file to
+ search for the public keys. More than one can be set. Add support
+ for searching keys from file.
- o Add init options to SilcAcceleratorObject as a SilcAcceleratorOption
- structure. Each accelerator defines the options that they support and
- can be retrieved from the SilcAccelerator with silc_acc_get_options.
- The format must also be machine parseable. The structure can be of the
- following format:
+ o Add silc_skr_find_add_search_dir that can be used to add a directory to
+ search for the public keys. More than one can be set. Add support
+ for seraching keys from directory.
- typedef struct SilcAcceleratorOptionStruct {
- const char *option; /* Option name */
- const char *display_name; /* Option displayable name */
- SilcParamType type; /* Option data format */
- } *SilcAcceleratorOption;
+ o SilcStack to SKR API.
- For software accelerator it could be for example:
- { "min_threads", "Minimum threads", SILC_PARAM_UINT32 },
- { "max_threads", "Maximum threads", SILC_PARAM_UINT32 },
+SILC Accelerator Library
+========================
- The accelerator itself doesn't have to use the option structure to
- parse the options if not wanted. It is defined for the caller so
- they can learn the supported options in a well defined way.
+ o Diffie-Hellman acceleration to SILC Accelerator API.
- o Diffie-Hellman acceleration
+ o Diffie-Hellman software acceleration.
- (o Symmetric key cryptosystem acceleration? They are always sycnhronouos
- even with hardware acceleration so the crypto API shouldn't require
- changes.) maybe
+ o Hardware acceleration through OCF (OCF-Linux,
+ http://ocf-linux.sourceforge.net).
+ o VIA Padlock support. See http://www.logix.cz/michal/devel/padlock/ and
+ Gladman's code.
-lib/silcmath
-============
+ o Implement GCM software acceleration.
- o Import TFM. We want TFM's speed but its memory requirements are
- just too much. By default it uses large pre-allocated tables which
- will eat memory when there are thousands of public keys in system.
- We probably want to change TFM's fp_int dynamic so that a specific
- size can be allocated for the int. We could have two new functions:
+ o Add hash function acceleration to SILC Accelerator API.
- SilcBool silc_mp_init_size(SilcMPInt *mp, SilcUInt32 bit_size);
- SilcBool silc_mp_sinit_size(SilcStack stack, SilcMPInt *mp,
- SilcUInt32 bit_size);
+ o SILC Accelerator API. Provides generic way to use different kind of
+ accelerators. Basically implements SILC PKCS API so that SilcPublicKey
+ and SilcPrivateKey can be used but they call the accelerators.
+ (***DONE)
- Which by default allocates `bit_size' bits instead of some default
- value. silc_mp_init would allocate the default FP_SIZE with TFM
- and do normal init with TMA and GMP. _init_size with TMA and GMP
- would be same as _init.
+ o Implement software accelerator. It is a thread pool system where the
+ public key and private key operations are executed in threads.
+ (***DONE)
- o Add AND, OR and XOR support to TFM or ask Tom to do it.
+ o Add SilcCipher support to SilcAccelerator and software accelerator.
+ Accelerate at least ciphers using CTR mode which can be done in
+ parallel. Do it in producer/consumer fashion where threads generate
+ key stream and other thread(s) encrypt using the key stream. (***DONE)
- o The SILC MP API function must start returning indication of success
- and failure of the operation.
- o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
- any other MP function (including utility ones) that may allocate
- memory.
+lib/silcmath
+============
- o Prime generation progress using callback instead of printing to
+ o Prime generation progress using callback instead of printing to
stdout.
o All utility functions should be made non-allocating ones.
+ o Import TFM. We want TFM's speed but its memory requirements are
+ just too much. By default it uses large pre-allocated tables which
+ will eat memory when there are thousands of public keys in system.
+ We probably want to change TFM. (***DONE)
-SILC XML Library, lib/silcxml/
-==============================
-
- o SILC XML API (wrapper to expat). Look at the expat API and simplify
- it. The SILC XML API should have at most 8-10 API functions. It should
- be possible to create full XML parser with only one function. And, it
- should be possible to have a function that is able to parse an entire
- XML document. It should also have a parser function to be able to
- parse a stream of XML data (SilcStream). It MUST NOT have operations
- that require multiple function calls to be able to execute that one
- operation (like creating parser).
-
+ o Add AND, OR and XOR support to TFM. (***DONE)
-lib/silcske/silcske.[ch]
-========================
+ o The SILC MP API function must start returning indication of success
+ and failure of the operation. (***DONE)
- o Ratelimit to UDP/IP transport for incoming packets.
+ o Do SilcStack support for silc_mp_init and other MP function
+ (including utility ones) that may allocate memory. (***DONE)
lib/silcasn1
lib/silcpgp
===========
- o OpenPGP certificate support, allowing the use of PGP public keys.
-
-
-lib/silcssh
-===========
-
- o SSH2 public key/private key support, allowing the use of SSH2 keys.
- RFC 4716. (***DONE)
-
-
-lib/silcpkix
-============
-
- o PKIX implementation
-
-
-apps/silcd
-==========
-
- o Deprecate the old server. Write interface for the new lib/silcserver
- server library. The interface should work on Unix/Linux systems.
-
- o Consider deprecating also the old config file format and use XML
- istead. This should require SILC XML API implementation first.
-
- o The configuration must support dynamic router and server connections.
- The silcd must work without specifying any servers or routers to
- connect to.
-
- o The configuration must support specifying whether the server is
- SILC Server or SILC Router. This should not be deduced from the
- configuration as it was in < 1.2.
-
- o The configuration must support specifying the ciphers and hmacs and
- their order so that user can specify which algorithms take preference.
-
-
-lib/silcserver
-==============
-
- o Rewrite the entire server. Deprecate apps/silcd as the main server
- implementation and create lib/silcserver/. It is a platform
- independent server library. The apps/silcd will merely provide a
- a simple interface for the library.
+ o OpenPGP certificate support, allowing the use of PGP public keys and
+ private keys.
- o Write the SILC Server library extensively using SILC FSM.
+ o Signatures for data, public keys and private keys (Signature packet).
- o Server library must support multiple networks. This means that one
- server must be able to create multiple connections that each reach
- different SILC network. This means also that all cache's etc. must
- be either connection-specific or network-specific.
+ o Signature verification from public keys, private keys and other signed
+ data (Signature packet).
- o Library must support dynamic router and server connections. This means
- that connections are create only when they are needed, like when someone
- says JOIN foo@foo.bar.com or WHOIS foobar@silcnet.org.
+ o Encryption and decryption support (Packet tags 8 and 18 most likely).
- o Library must support server-to-server connections even though protocol
- prohibits that. The responder of the connection should automatically
- act as a router. The two servers create an own, isolated, SILC network.
- To be used specifically with dynamic connections.
+ o Retrieval of User ID from public key and private key (Used ID packet
+ and User Attribute packet).
- o Library must support multiple threads and must be entirely thread safe.
+ o Creation of OpenPGP key pairs.
- o Library must have support for SERVICE command.
+ o Trust packet handling (GNU PG compatible) from public and private keys.
- o Both UDP and TCP support for incoming connecetions. Maintaining long
- term UDP sessions.
+ o Add option that the signature format doesn't use the OpenPGP format
+ but whatever is the default in SILC crypto library.
- o The server must be able to run behind NAT device. This means that
- Server ID must be based on public IP instead of private IP.
- o The following data must be in per-connection context: client id cache,
- server id cache, channel id cache, all statistics must be
- per-connection.
-
- o The following data must be in per-thread context: command context
- freelist/pool, pending commands, random number generator.
-
- o Do inccoming packet processing in an own FSM thread in the
- server-threads FSM. Same as in client library.
+lib/silcssh
+===========
- o Binding to other ports than 706 too. To allow easier traversing
- through NATs and firewalls server should bind to 80, 443 and 7706
- by default (at least try to bind). Connections must work normally
- even if they were established to some other port other than 706.
+ o Add option that the signature format doesn't use the SSH2 protocol
+ but whatever is the default in SILC crypto library;
+ silc_ssh_private_key_set_signature_type, or something.
- Connection option that attemps to connect to remot server with various
- different mechanisms: UDP 706, TCP 706, TCP 80, TCP 443, UDP 7706 and
- TCP 7706. This is the so called hole punching mechanism.
+ o SSH2 public key/private key support, allowing the use of SSH2 keys.
+ RFC 4716. (***DONE)
- o Ability to recover from rekey errors, at least try to.
- o Reference count all Silc*Entry structures.
+lib/silcpkix
+============
- Some issues that must be kept in mind from 1.0 and 1.1 silcd's:
+ o PKIX implementation
- o The server and router software MUST work out of the box. After
- installation the server must not require any configuration to run the
- most basic working configuration. No defining IP addresses, etc.
- The server must work just by running it.
- o The SERVER_SIGNOFF notify handing is not optimal, because it'll
- cause sending of multiple SIGNOFF notify's instead of the one
- SERVER_SIGNOFF notify that the server received. This should be
- optimized so that the only SERVER_SIGNOFF is sent and not
- SIGNOFF of notify at all (using SIGNOFF takes the idea about
- SERVER_SIGNOFF away entirely).
+lib/silccms
+===========
- o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
- sent to a client if it is on same channel as the client that
- signoffed. However, the entire SERVER_SIGNOFF list is sent to
- the client, ie. it may receive clients that was not on the
- same channel. This is actually against the specs. It must be
- done per channel. It shouldn't receive the whole list just
- because one client happened to be on same channel.
+ o Cryptographic Message Syntax (RFC 3852), the former PKCS #7
- o If client's public key is saved in the server (and doing public key
- authentication) then the hostname and the username information could
- be taken from the public key. Should be a configuration option!
- o Add a timeout to handling incoming JOIN commands. It should be
- enforced that JOIN command is executed only once in a second or two
- seconds. Now it is possible to accept n incoming JOIN commands
- and process them without any timeouts. THis must be employed because
- each JOIN command will create and distribute the new channel key
- to everybody on the channel.
+lib/silcsmime
+=============
- o Related to above. If multiple JOINs are received in sequence perhaps
- new key should be created only once, if the JOINs are handeled at the same
- time. Now we create multiple keys and never end up using them because
