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. + + +Crypto Library, lib/silccrypt/ ============================== - o Testing - See test plan: - http://silcnet.org/docs/silc-client-1.0-test.pdf - http://silcnet.org/docs/silc-client-1.0-test.ps + 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 Add CMAC and maybe others. Change needs rewrite of the internals of + the SILC Mac API, currently it's suitable only for HMACs. + + o Global RNG must be changed to use SILC Global API. + + o Global cipher, hash, mac, and pkcs tables must use SILC Global API. + + o Add FIPS compliant RNG. + + 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. + + o Add ECDSA support. + + o Add ECDH support. + + o Add PKCS#1 RSAES-OAEP and RSASSA-PSS. + + o Add GCM mode. + + o Do GCC vs ICC benchmarks of all key algorithms. + + o Add DSA support to SILC public key. + + 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 AES CBC is missing proper alignment code. (***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 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 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) + + 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 + 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 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) + + o Add DSS support. (***DONE) + + o All cipher, hash, hmac etc. allocation routines should take their name + in as const char * not const unsigned char *. (***DONE) + + +SKR Library, lib/silcskr/ +========================= + + o Add fingerprint as search constraint. + + o Add SSH support. (***DONE, TESTING NEEDED) + + 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 Add find rule AND and OR. The default is always AND. Add + silc_skr_find_set_rule. -TODO for SILC Server 1.0 + 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 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 SilcStack to SKR API. + + +SILC Accelerator Library ======================== - o INVITE and BAN notifys send the entire list as notify, but only the - added/removed info should be sent. + o Diffie-Hellman acceleration to SILC Accelerator API. + + o Diffie-Hellman software acceleration. + + 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. + + o Implement GCM software acceleration. + + o Add hash function acceleration to SILC Accelerator API. + + 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 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/silcmath +============ + + 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) + + o Add AND, OR and XOR support to TFM. (***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/silcasn1 +============ + + o Negative integer encoding is missing, add it. + + 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/silcpgp +=========== + + o OpenPGP certificate support, allowing the use of PGP public keys and + private keys. + + o Signatures for data, public keys and private keys (Signature packet). + + o Signature verification from public keys, private keys and other signed + data (Signature packet). + + 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). + + o Creation of OpenPGP key pairs. + + o Trust packet handling (GNU PG compatible) from public and private keys. - o The CMODE cipher & hmac change problem (#101). + o Add option that the signature format doesn't use the OpenPGP format + but whatever is the default in SILC crypto library. - o Fix CUMODE_CHANGE and CMODE_CHANGE for founder key things. - o 1.2 backup router support +lib/silcssh +=========== - o Testing + 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 SSH2 public key/private key support, allowing the use of SSH2 keys. + RFC 4716. (***DONE) -TODO/bugs In SILC Libraries -=========================== - o Test cases for all cryptographic primitive in lib/silccrypt/ +lib/silcpkix +============ - o Test cases for all payload encoding and decoding routins in lib/silccore/ + o PKIX implementation - o Test cases for math library routines in lib/silcmath/ +lib/silccms +=========== -TODO in Toolkit Documentation -============================= + o Cryptographic Message Syntax (RFC 3852), the former PKCS #7 -Stuff that needs to be done in order to complete the Tooolkit Reference -Manual (Do these to 0.9.x). - 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/silcsmime +============= - o Searching of predefined keywords, exact and partial matches (would be - nice). + o S/MIME (RFC 3851)
