| 2020-05-06 | If a hash core can't restore state, use a soft core instead. | Paul Selkirk | |
| 2018-07-25 | Merge branch 'hashsig' | Paul Selkirk | |
| 2018-07-16 | No-op out core alloc/free when no cores exist. | Rob Austein | |
| 2018-05-20 | Drop <assert.h> now that everything should be using hal_assert() instead. | Rob Austein | |
| 2018-05-20 | Better hal_core_alloc() semantics, assert() and printf() cleanup. | Rob Austein | |
| Various fixes extracted from the abandoned(-for-now?) reuse-cores branch, principally: * Change hal_core_alloc*() to support core reuse and to pick the least-recently-used core of a particular type otherwise; * Replace assert() and printf() calls with hal_assert() and hal_log(), respectively. assert() is particularly useless on the HSM, since it sends its error message into hyperspace then hangs the HSM. | |||
| 2017-10-23 | Cleanup signed/unsigned mismatches, mostly in loop counters | Paul Selkirk | |
| 2017-07-31 | Unconditionally set the allocated flag when initializing a hash state | Paul Selkirk | |
| structure. When running multiple concurrent unit tests, I observed multiple failures in the hmac tests, which I ultimately tracked down to different clients sharing the same hal_hmac_state struct. hal_hash_initialize is called twice in hal_hmac_initialize (once to get the state structure, then again if the supplied key is too long), and is called in hal_hmac_finalize, to hash the digest with the supplied key. In these subsequent cases, the caller supplies the state structure, which hal_hash_initialize zeroes, but it doesn't set the allocated flag. This marks an in-use struct as available, so it gets reassigned and reinitialized, and Bad Things Happen for both clients that are trying to use it. | |||
| 2016-12-19 | Merge branch 'master' into ksng | Rob Austein | |
| 2016-10-25 | Uppercase HAL_DIGEST_ALGORITHM_ symbols for API consistency. | Rob Austein | |
| 2016-09-20 | Clean up the defines around rpc client, software hash cores, etc. | Paul Selkirk | |
| 2016-09-01 | Move in-memory keystore from client to server. Whack with club until compiles. | Rob Austein | |
| Fixes for various minor issues found while integrating with sw/stm32. Moving the in-memory keystore (PKCS #11 session objects, etc) from the client library to the HSM was on the near term to-do list in any case, doing it now turned out to be the easiest way to solve one of the build problems. | |||
| 2016-07-05 | Attempt to add resource management, for multiple cores of the same type. | Paul Selkirk | |
| Find a suitable core, and mark it busy. Don't forget to release it as soon as you're done. This has a knock-on effect of un-const'ing core arguments and struct fields in a lot of places, and it moves some core checks around. | |||
| 2016-06-09 | Typo in SHA-224/SHA-256 software core. | Rob Austein | |
| 2016-05-31 | SHA-224 driver and soft core. | Rob Austein | |
| 2016-05-15 | Silence unused variable warning. | Rob Austein | |
| 2016-05-14 | Trailing whitespace cleanup. | Rob Austein | |
| 2016-03-29 | Enable 'mixed' mode, with client-side hashing. | Paul Selkirk | |
| 2016-03-21 | Merge branch 'master' into rpc | Paul Selkirk | |
| 2016-03-16 | Added serial RPC transport and lots more... | Paul Selkirk | |
| Added RPC function to get server version number. Substantially reworked GNUMakefile with conditionals. Renamed rpc_*() and xdr_*() to hal_*() for consistency. Moved hal_io_fmc.c from stm32 repo. | |||
| 2016-03-09 | Tweak handling of byte swapping in software hash cores to get rid of | Rob Austein | |
| some unnecessary data copying. | |||
| 2016-03-09 | Optional (compile time conditional) software hash cores. At the | Rob Austein | |
| moment this is all-or-nothing, but could easily be tweaked to allow compile-time selection of particular hashes. | |||
| 2015-12-23 | RPC interface to TRNG and (incomplete) PIN code. | Rob Austein | |
| 2015-12-13 | Merge Paul's copyright updates. | Rob Austein | |
| 2015-12-13 | whack copyrights | Paul Selkirk | |
| 2015-12-13 | Add rpc_hash.c. Convert dynamic allocator in hash.c to use private | Rob Austein | |
| pool of pre-configured state blocks, suitable for an embedded system. | |||
| 2015-11-13 | Merge branch 'config_core_selector' | Paul Selkirk | |
| 2015-10-29 | Remove unused includes. | Paul Selkirk | |
| 2015-10-04 | Whack libhal API to use current configure_core_selector mechanism. | Rob Austein | |
| Compiles, not yet tested. | |||
| 2015-10-04 | off_t => hal_addr_t. | Rob Austein | |
| 2015-09-08 | Merge branch 'master' into ecdsa | Rob Austein | |
| This required a bit of manual cleanup in hal.h, hash.c, and rsa.c. No intended changes to functionality provided by parent comments, just a few tweaks to track API changes beyond git's ken. | |||
| 2015-09-06 | Add ECPoint I/O functions. ASN.1 cleanup. | Rob Austein | |
| 2015-09-02 | Clean up excessively complicated handling of opaque types in hash and | Rob Austein | |
| RSA code; use simpler model (pointer to incomplete structure) used in ECDSA code. Refactor RSA code to use shared ASN.1 routines. | |||
| 2015-07-18 | Add support for dynamic allocation of hash and HMAC state, for cases | Rob Austein | |
| where it's unavoidable. | |||
| 2015-07-17 | First cut at libhal support for hash cores with ability to save and | Rob Austein | |
| restore internal state. Compiles, not yet tested. | |||
| 2015-06-21 | libcryptech -> libhal, doh. | Rob Austein | |
| 2015-06-21 | Add digest algorithm IDs. | Rob Austein | |
| 2015-06-05 | HMAC for truncated SHA-512 digests would probably work better if we | Rob Austein | |
| used the right digest length constants. Doh. | |||
| 2015-06-04 | First cut at PBKDF2. | Rob Austein | |
| 2015-06-04 | Disable HMAC-SHA-384 tests as neither my implementation nor PyCrypto | Rob Austein | |
| passes them. Add missing copyright notices, other trivial cleanup (whitespace, etc). | |||
| 2015-06-04 | Whoops, we're supposed to hash an entire block for the key regardless | Rob Austein | |
| of how long the key is. With this fix, HMAC passes tests on Novena. | |||
| 2015-06-04 | HMAC implementation and test vectors. | Rob Austein | |
| 2015-06-04 | Refactor hash code prior to adding HMAC (which we need for PBKDF2). | Rob Austein | |
| Main changes: moving the ten zillion core-related constants from closures into a driver structure, rework API to the more common initialize/update/finalize because it's easier to understand, particularly with HMAC. | |||
| 2015-05-25 | Cleanup: names of *_core_present() functions, Makefile. | Rob Austein | |
| 2015-05-24 | Debug hash-testing code. | Rob Austein | |
| 2015-05-20 | Add AES Key Wrap using Cryptech AES core. | Rob Austein | |
| 2015-05-20 | Add csprng and hash modules. Add real error codes instead of magic | Rob Austein | |
| numbers, and propegate error codes up from lower layers. Whack C++-isms, add parenthesese to a lot of macro expressions for evaluation safety, other minor cleanup. | |||
