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. -lib/silcclient, The Client Library ***PARTLY DONE**** -================================== +Crypto Library, lib/silccrypt/ +============================== - o silcclient.h clean up and API rewrites. (***DONE) + o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h, and + possibly to silcpkcs.h. - o silcclient_entry.h finishing, all entry relates APIs to this header. - (***DONE) + /* 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 SilcChannelEntry, SilcServerEntry, SilcChannelUser, allocating, - freeing, finding, etc. rewrite. Also making them reference counted for - multi threads use. (***DONE) + 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 Rewrite silc_client_get_clients_by_channel. + o Global RNG must be changed to use SILC Global API. - o Rewrite client side WHOIS command (for whois -details). (***DONE) + o Global cipher, hash, mac, and pkcs tables must use SILC Global API. - o Finish all the missing SILC packet processings, rewrites. (***DONE) + o Add FIPS compliant RNG. - o The client_notify.c rewrite. (***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 Resuming to client_register.c (remove client_resume.c) (***DONE) + o Add Elgamal. - o Rekey rewrite. (***DONE) + o Add ECDSA support. - o Remove protocol.[ch]. (***DONE) + o Add ECDH support. - o File transfer rewrite. (***DONE) + o Add PKCS#1 RSAES-OAEP and RSASSA-PSS. - o File transfer API documentation. (***DONE) + o Add GCM mode. - o Connection auth request. (***DONE) + o Do GCC vs ICC benchmarks of all key algorithms. - o Password auth test, public key auth test. (***TESTING NEEDED) + o Add DSA support to SILC public key. - o Starting key exchange directly, rewrite. (***DONE) + 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 Channel messages, channel private keys, channel entires, channel - search, etc. rewrite. (***TESTING NEEDED) + o AES CBC is missing proper alignment code. (***DONE) - o For many APIs leave the hash context allocations to the caller instead - of using client->sha1hash and client->md5hash, or some kind of thread - safe (no locking) concept. (***DONE) + o silc_pkcs_public_key_alloc should accept also SILC_PKCS_ANY as argument + and try all supported PKCS until one succeeds. (***DONE) - o Key agreement rewrite. (***TESTING NEEDED) + 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 Connecting to remote client (***DONE) + o Document all cipher names, hash names, mac names, pkcs names. (***DONE) - o Private message waiting API (in threads) (***TESING NEEDED) + 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) - o client_attrs.c, attributes rewrite. (***TESTING NEEDED) - - o No SilcBuffer lists back to application in command_reply operations. - Convert them all to real lists and/or structures for easier use. - (***DONE) + o Change the DSA implementation to support FIPS186-3.

(***TESTING NEEDED) - - -lib/silcsftp ****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 + 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 Porting to use the new util library. (***DONE) + 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) + 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) -lib/silccore/silcpacket.[ch] ****PARTLY DONE**** -============================ + o Add DSS support. (***DONE) - o SilcPacketEngine.

(***DONE, TESTING NEEDED) -lib/silccore/silcid.[ch] ****DONE**** -======================== + o Add OpenPGP support. Adding, removing, fetching PGP keys. (Keyring + support?) - o Add silc_id_str2id to accept the destination buffer as argument - and thus not require any memory allocation. Same will happen - with silc_id_payload_* functions. (***DONE) + 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_id_str2id, silc_id2str to non-allocating routines. (***DONE) + o Add find rule AND and OR. The default is always AND. Add + silc_skr_find_set_rule. + 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. -lib/silcskr ****DONE**** -=========== + 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. - o Removing key from the repository is not possible currently. It should - be. (***DONE) + o SilcStack to SKR API. -lib/silcske/silcske.[ch] ***PARTLY DONE**** +SILC Accelerator Library ======================== - o Responder rekey (***TESTING NEEDED) - - o IV Included flag support in SKE (***DONE) + o Diffie-Hellman acceleration to SILC Accelerator API. - o UDP transport changes; retransmission support by using exponential - backoff algorithm. (***DONE) + o Diffie-Hellman software acceleration. - o SilcConnAuth header file documentation. (***DONE) + 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/silccrypt ****PARTLY DONE**** -============= + o Implement GCM software acceleration. - o Implement PKCS #1 sign/verify with hash OID. (***TESTING NEEDED) + o Add hash function acceleration to SILC Accelerator API. - o Implement SILC Public Key Version 2 handling in sign/verify. Implement - Version (V) identifier (***DONE) + 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 SILC PKCS (silcpkcs.h) reorganizing when other PK supports added. - Move the SILC Public Key routines away from the crypto library into - the core library (silccore). silc_pkcs_public/private_key_* routines - to silc_public/private_key_* routines. The silc_public_key_* routines - should also automatically handle SILC Public Keys, and other keys - and certificates as well. Add fe. silcpk.h into silccore. It should - also include the Public Key Payload encoding and decoding routines. + o Implement software accelerator. It is a thread pool system where the + public key and private key operations are executed in threads. (***DONE) - o Assembler AES (***DONE) + 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) -lib/silcutil ****PARTLY DONE**** +lib/silcmath ============ - o The regex code from lib/contrib might compile fine on all platforms. - No need to make it silcutil/unix/ specific. Add them to generic - silcutil.c. (***TESTNG NEEDED) + o Prime generation progress using callback instead of printing to + stdout. - o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h) (***TESTING NEEDED) + o All utility functions should be made non-allocating ones. - o bool -> SilcBool (***DONE) + 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) + o Add AND, OR and XOR support to TFM. (***DONE) -lib/silcutil/silcbuffer.h ****DONE**** -========================= - - o Remove the `truelen' field from SilcBuffer as it is entirely - redundant since we can get the true length of the buffer by - doing buffer->end - buffer->header. Add silc_buffer_truelen - macro instead. Consider also removing `len' field too since - it effectively is buffer->tail - buffer->data, and adding - silc_buffer_len macro can do the same. These would save - totally 8 bytes of memory per buffer. (***DONE) + o The SILC MP API function must start returning indication of success + and failure of the operation. (***DONE) + o Do SilcStack support for silc_mp_init and other MP function + (including utility ones) that may allocate memory. (***DONE) -lib/silcutil/silcbuffmt.[ch] ****DONE**** -============================ - o SilcStack aware silc_buffer_unformat (***DONE) - - o SilcStack aware silc_buffer_format (***DONE) - - o silc_buffer_format reallocates automatically (***DONE) - - o SILC_STR_OFFSET (***DONE) - - -lib/silcutil/silcstack.[ch] ****DONE**** -=========================== - - o Data stack implementation (***DONE) - - -lib/silcutil/silcstream.[ch] ****DONE**** -============================ - - o Add abstract SilcStream. (***DONE) - - -lib/silcutil/silcsocketstream.[ch] ****PARTY DONE**** -================================== - - o Add SilcSocketStream (***DONE) - - o Add SilcSocketStream for WIN32 (***TESTING NEEDED) - - o Test QoS after the changes made to socket stream - - -lib/silcutil/silcschedule*.[ch] ****PARTLY DONE**** -=============================== - - o Scheduler can be optimized for FD tasks by changing the fd_queue - to SilcHashTable instead of using linked list. We need to do - one-to-one mapping of FD to task and hash table is more efficient - for this usage. - - Also redefine the silc_select to perhaps return a separate - structure of the events that actually occurred, instead of - returning the events in the fd_list which is then traversed - in the generic code to find the changed events. This can be - made faster by having own struct which includes only the - changed events, thus the tarversing is faster since the whole - fd_list is not traversed anymore (it is still traversed in the - silc_select but at least it removes one extra tarversing later - for the same list). - - Other task queues should be changed to use SilcList. (***DONE) - - o Add SILC scheduler's internal routines into a table of implementation - function pointers, that the generic code then takes as extern from - implementation. These are the silc_schedule_internal_* routines. - (***DONE) +lib/silcasn1 +============ - o Change SILC_TASK_CALLBACK to non-static, and remove the macro - SILC_TASK_CALLBACK_GLOBAL. (***DONE) + o Negative integer encoding is missing, add it. - o SILC Schedule API changes to WIN32. (***TESTING NEEDED) + 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) -lib/silcutil/silcasync.[ch] ****DONE**** -=========================== - o Add SilcAsyncOperation to utility library. Any function that takes - callback as an argument must/should return SilcAsyncOperation. - (***DONE) +lib/silcpgp +=========== + o OpenPGP certificate support, allowing the use of PGP public keys and + private keys. -lib/silcutil/silctime.[ch] ****DONE**** -=========================== + o Signatures for data, public keys and private keys (Signature packet). - o SilcTime. (***DONE) + o Signature verification from public keys, private keys and other signed + data (Signature packet). - o system time, universal, generalized. (***DONE) + o Encryption and decryption support (Packet tags 8 and 18 most likely). + o Retrieval of User ID from public key and private key (Used ID packet + and User Attribute packet). -lib/silcutil/silcfsm.[ch] ****DONE**** -========================= + o Creation of OpenPGP key pairs. - o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE) + o Trust packet handling (GNU PG compatible) from public and private keys. + o Add option that the signature format doesn't use the OpenPGP format + but whatever is the default in SILC crypto library. -lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE**** -=============================================== - o Add UDP interface (***DONE) +lib/silcssh +=========== - o Add UDP interface for WIN32 (***TESTING NEEDED) + 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. - o New network interfaces (***DONE) + o SSH2 public key/private key support, allowing the use of SSH2 keys. + RFC 4716. (***DONE) -lib/silcmath ****PARTLY DONE**** +lib/silcpkix ============ - o Test on x86_64. - - o Change LTM and TFM function names when importing to SILC tree to avoid - rare linking problems on system that has same named symbols already in - the system. (***DONE) - - -lib/silcutil/symbian/ ****PARTLY DONE**** -===================== + o PKIX implementation - o lib/silcutil/symbian routines missing or not completed. - (****TESTING NEEDED) - - 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. +lib/silccms +=========== -lib/silcasn1 ****DONE**** -============ + o Cryptographic Message Syntax (RFC 3852), the former PKCS #7 - o ASN.1 library (***DONE) - o Header documentation missing. (***DONE) +lib/silcsmime +============= - o Some string encodings missing (copy/paste matter). (***DONE) + o S/MIME (RFC 3851)
