For 1.06
For 1.07
1. [3 hours] ASN.1 SET and T61String [punishment, add UTF8 to the list!]
1. export ECC functions globally [e.g. mulmod and the sets]
- goal is tv_gen module and test vectors
2. ASN.1 SET and T61String
3. phase out DH code [RSA/ECC/DSA is enough]
4. Some ASN.1 demo programs [for now read the source code!]
5. Start working towards making the bignum code plugable
6. Look into other ECC point muls and consider a "precomp" interface
7. Add OID for ciphers and PRNGs to their descriptors

v1.06 -- Fixed rand_prime() to accept negative inputs as a signal for BBS primes. [Fredrik Olsson]
-- Added fourth ARGCHK type which outputs to stderr and continues. Useful if you trap sigsegv. [Valient Gough]
-- Removed the DH code from the tree
-- Made the ECC code fully public (you can access ecc_mulmod directly now) useful for debuging
-- Added ecc test to tv_gen
-- Added hmac callback to hash descriptors.
-- Fixed two doxy comment errors in the UTCTIME functions
-- rsa_import() can now read OpenSSL format DER public keys as well as the PKCS #1 RSAPublicKey format.
Note that rsa_export() **ONLY** writes PKCS #1 formats
-- Changed MIN/MAX to only define if not already present. -- Kirk J from Demonware ...
-- Ported tv_gen to new framework (and yes, I made ecc vectors BEFORE changing the API and YES they match now :-))
-- ported testing scripts to support pluggable math. yipee!
-- Wrote a TFM descriptor ... yipee
-- Cleaned up LTC_FAST in CBC mode a bit
-- Merged in patches from Michael Brown for the sparc/sparc64 targets
-- Added find_hash_oid() to search for a hash by its OID
-- Cleaned up a few stray CLEAN_STACKs that should have been LTC_CLEAN_STACK
-- Added timing resistant ECC, enable by defining LTC_ECC_TIMING_RESISTANT then use ECC API as normal
-- Updated the ECC documentation as it was a bit out of date
June 27th, 2005
v1.05
-- Added Technote #6 which covers the current PK compliance.

You can disable whole classes of algorithms on the command line with the LTC_NO_* defines. From there you can manually turn on what you want to enable.
The following build with GCC 3.4.3 on an AMD64 box gets you AES, CTR mode, SHA-256, HMAC, Yarrow, full RSA PKCS #1, PKCS #5, ASN.1 DER and MPI in
roughly 80KB of code.
The following build with GCC 3.4.4 on an AMD64 box gets you AES, CTR mode, SHA-256, HMAC, Yarrow, full RSA PKCS #1, PKCS #5 and ASN.1 DER in
roughly 40KB of code (49KB on the ARMv4) (both excluding the math library).
CFLAGS="-DSC_RSA_1 -DLTC_NO_CIPHERS -DLTC_NO_HASHES -DLTC_NO_PRNGS -DLTC_NO_MACS -DLTC_NO_MODES -DLTC_NO_PK -DRIJNDAEL -DCTR -DSHA256 \

Obviously this won't get you performance but if you need to pack a crypto lib in a device with limited means it's more than enough...
Neato eh?
