v0.90 -- new ROL/ROR for x86 GCC
-- Jochen Katz submitted a patch to the makefile to prevent "make" from making the .a library
when not required.
== By default the KR code is not enabled [it's only a demo anyways!]
-- changed the "buf" in ecc_make_key from 4KB to 128 bytes [since the largest key is 65 bytes]
-- hmac_done() now requires you pass it the size of the destination buffer to prevent
buffer overflows. (API CHANGE)
-- hmac/hash filebased routines now return CRYPT_NOP if NO_FILE is defined.
-- I've removed the primes from dh.c and replaced them with DR safe primes suitable for the default
configuration of LibTomMath. Check out these comparisons on a 1.3Ghz Athlon XP, optimized for size,
768-bit, 4 vs. 10
1024-bit, 8 vs. 18
1280-bit, 12 vs. 34
1536-bit, 20 vs. 56
1792-bit 28 vs. 88
2048-bit, 40 vs. 124
2560-bit, 71 vs. 234
3072-bit, 113 vs. 386
4096-bit, 283 vs. 916
Times are all in milliseconds for key generation. New primes times on the left. This makes the code binary
incompatible with previous releases. However, this addition is long overdue as LibTomMath has supported DR
reductions for quite some time.
-- Added RIPE-MD 128 and 160 to the list of supported hashes [10 in total].
-- The project has been released as public domain. TDCAL no longer applies.
July 15th, 2003
v0.89 -- Fix a bug in bits.c which would prevent it from building with msvc
-- Merged in LibTomMath v0.24 [and I used the alloc/free macros this time!]

``hmac'' is the HMAC state you are working with. ``hashOut'' is the array of octets where the HMAC code should be stored. You must
set ``outlen'' to the size of the destination buffer before calling this function. It is updated with the length of the HMAC code
produced (depending on which hash was picked)
There are two utility functions provided to make using HMACs easier todo. They accept the key and information about the
message (file pointer, address in memory) and produce the HMAC result in one shot. These are useful if you want to avoid
