-TODO/bugs in Irssi SILC client
+TODO for 1.2 And Beyond
+=======================
+
+NOTE: Any item that doesn't have (***DONE) in it, isn't done yet. The
+(***TESTING NEEDED) means that the item has been done but not yet properly
+tested.
+
+NOTE: A TODO entry does not mean that it is ever going to be done. Some
+of the entries may be just ideas, good, bad or ugly. If you want to work
+on some of the TODO entries simply let us know about it by dropping a note
+to silc-devel mailing list or appear on 'silc' channel on SILCNet.
+
+
+SKR Library, lib/silcskr/
+=========================
+
+ o Add fingerprint as search constraint.
+
+ o Add OpenPGP support. Adding, removing, fetching PGP keys. (Keyring
+ support?)
+
+ 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 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:
+
+ 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);
+
+ NULL argument would be ignored and skipped.
+
+ o Add OR logical rule in addition of the current default AND, eg:
+
+ // 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);
+
+ // 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 SilcStack to SKR API.
+
+
+Crypto Library, lib/silccrypt/
==============================
- o add --with-iconv
+ 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
+ library. It should not be necessary anymore to separately register
+ default ciphers, HMACs, etc, the _init would do that. However, if
+ user after _init calls silc_pkcs_register, for example, it would take
+ preference over the default once, ie. user can always dictate the
+ order of algorithms. (***DONE)
- o UTF-8 encode/decode WHOIS userinfos, topic, etc.
+ o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h, and
+ possibly to silcpkcs.h.
- o Testing
+ /* 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)
-TODO/bugs In SILC Client Library
-================================
+ 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.
- o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
- though). This should be added and perhaps new client operation
- should be added to notify application that it was received and
- set the key only if application wishes to set (accept the key) it
- (Do this to 0.9.x).
+ o Change PKCS Algorithm API to take SilcPKCSAlgorithm as argument to
+ encrypt, decrypt, sign and verify functions. We may need to for exmaple
+ check the alg->hash, supported hash functions. Maybe deliver it also
+ to all other functions in SilcPKCSAlgorithm to be consistent. (***DONE)
- o Testing
+ o Add DSA support to SILC public key.
+ o Add DSS support. (***DONE)
-TODO/bugs In SILC Server
+ 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 ECDSA support.
+
+ o Add ECDH support.
+
+ o AES CBC is missing proper alignment code (see silc_1_1_branch).
+
+ o All cipher, hash, hmac etc. allocation routines should take their name
+ in as const char * not const unsigned char *. (***DONE)
+
+
+SILC Accelerator Library
========================
- o Implement the <Requested Attributes> and the Attribute Payload to
- the core library, client and server. Maybe implementations of
- RFC 2425 and RFC 2426 to make it complete.
+ 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 Implement software accelerator. It is a thread pool system where the
+ public key and private key operations are executed in threads.
+ (***DONE)
+
+ 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:
+
+ typedef struct SilcAcceleratorOptionStruct {
+ const char *option; /* Option name */
+ const char *display_name; /* Option displayable name */
+ SilcParamType type; /* Option data format */
+ void *default_value; /* Option's default value */
+ SilcUInt32 default_value_len; /* Default value length */
+ } *SilcAcceleratorOption;
+
+ For software accelerator it could be for example:
+
+ { "min_threads", "Minimum threads", SILC_PARAM_UINT32, (void *)2, 4 },
+ { "max_threads", "Maximum threads", SILC_PARAM_UINT32, (void *)4, 4 },
+
+ o Diffie-Hellman acceleration
+
+ (o Symmetric key cryptosystem acceleration? They are always sycnhronouos
+ even with hardware acceleration so the crypto API shouldn't require
+ changes.) maybe
+
+
+lib/silcmath
+============
- o Add special handling in router and server for "connection timed out"
- error. Be optimistic.
+ 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 Backup router related issues (Fix this to 0.9.x):
+ SilcBool silc_mp_init_size(SilcMPInt *mp, SilcUInt32 bit_size);
+ SilcBool silc_mp_sinit_size(SilcStack stack, SilcMPInt *mp,
+ SilcUInt32 bit_size);
- o Complete backup router support with standalone router
+ 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 Make the backup router work even if not all servers in the
- cell use it. When primary goes down, also those that are
- not using it (are not connected locally) are signoffed.
+ o Add AND, OR and XOR support to TFM or ask Tom to do it.
- o When primary goes down and removing clients of non-backup
- aware server the SERVER_SIGNOFF includes the router's ID
- not the server's ID, which it should include. The notify
- is sent by backup.
+ o The SILC MP API function must start returning indication of success
+ and failure of the operation.
- o Testing
+ 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.
- 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 (Fix this to 0.9.x).
+ o Prime generation progress using callback instead of printing to
+ stdout.
- 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 All utility functions should be made non-allocating ones.
- o Testing
+lib/silcasn1
+============
-TODO/bugs In SILC Libraries
-===========================
+ o Negative integer encoding is missing, add it.
- o WIN32 silc_net_create_connection_async does not work the same way
- than on Unix. Do it with threads on WIN32. The function works but
- is not actually async currently (Fix this to 0.9.x).
+ o SILC_ASN1_CHOICE should perhaps return an index what choice in the
+ choice list was found. Currently it is left for caller to figure out
+ which choice was found. (***DONE)
+ o SILC_ASN1_NULL in decoding should return SilcBool whether or not
+ the NULL was present. It's important when it's SILC_ASN1_OPTIONAL
+ and we need to know whether it was present or not. (***DONE)
-TODO in Toolkit Documentation
-=============================
-Stuff that needs to be done in order to complete the Tooolkit Reference
-Manual (Do these to 0.9.x).
+lib/silcpgp
+===========
- o ROBOdoc documenting missing from lib/silcutil/silcbuffer.h.
+ o OpenPGP certificate support, allowing the use of PGP public keys.
- o ROBOdoc documenting missing from lib/silcutil/silcdlist.h.
- o ROBOdoc documenting missing from lib/silcutil/silcfileutil.h.
+lib/silcssh
+===========
- o ROBOdoc documenting missing from lib/silccrypt/silccipher.h.
+ o SSH2 public key/private key support, allowing the use of SSH2 keys.
+ RFC 4716. (***DONE)
- o ROBOdoc documenting missing from lib/silccrypt/silcpkcs.h.
- o Write "Programming with Toolkit" document, describing how to build
- Toolkit, how the build system works, where is everything, how
- new (external) projects can be glued into Toolkit (use irssi as an
- example), and how external projects can use Toolkit without gluing into
- it (how to link etc), debugging, architecture, types, etc.
+lib/silcpkix
+============
- o Write "Platform Implementations" document to describe what platforms
- Toolkit support, what has been implemented, what has not been, what
- works differently etc.
+ o PKIX implementation
