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.
