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 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 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 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) + + 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 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 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. -TODO for SILC Server 1.0 + 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 INVITE and BAN notifys send the entire list as notify, but only the - added/removed info should be sent. + 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 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: + + SilcBool silc_mp_init_size(SilcMPInt *mp, SilcUInt32 bit_size); + SilcBool silc_mp_sinit_size(SilcStack stack, SilcMPInt *mp, + SilcUInt32 bit_size); + + 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 Add AND, OR and XOR support to TFM or ask Tom to do it. + + 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. + + o Prime generation progress using callback instead of printing to + stdout. + + o All utility functions should be made non-allocating ones. - o The CMODE cipher & hmac change problem (#101). - o Fix CUMODE_CHANGE and CMODE_CHANGE for founder key things. +lib/silcasn1 +============ - o 1.2 backup router support + o Negative integer encoding is missing, add it. - o Testing + 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/bugs In SILC Libraries -=========================== - o Test cases for all cryptographic primitive in lib/silccrypt/ +lib/silcpgp +=========== - o Test cases for all payload encoding and decoding routins in lib/silccore/ + o OpenPGP certificate support, allowing the use of PGP public keys. - o Test cases for math library routines in lib/silcmath/ +lib/silcssh +=========== -TODO in Toolkit Documentation -============================= + o SSH2 public key/private key support, allowing the use of SSH2 keys. + RFC 4716. (***DONE) -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/silcpkix +============ - o Searching of predefined keywords, exact and partial matches (would be - nice). + o PKIX implementation
