However, during the operation [e.g. CCM] if the descriptor has been altered the results will be + undefined. + -- Minor updates to the manual to reflect recent changes + -- Added a catch to for an error that should never come up in rsa_exptmod(). Just being thorough. + +June 15th, 2005 +v1.04 + -- Fixed off by one [bit] error in dsa_make_key() it was too high by one bit [not a security problem just inconsistent] + -- ECC-224 curve was wrong [it was an ok curve just not NIST, so no security flaw just interoperability]. + -- Removed point compression since it slows down ECC ops to save a measly couple bytes. + This makes the ecc export format incompatible with 1.03 [it shouldn't change in the future] + -- Removed ECC-160 from timing and added the other curves + +June 9th, 2005 +v1.03 + -- Users may want to note that on a P4/GCC3.4 platform "-fno-regmove" greatly accelerates the ciphers/hashes. + -------------------------------------------------------------------------------------------------------------- + -- Made it install the testing library in the icc/static makefiles + -- Found bug in ccm_memory.c which would fail to compile when LTC_CLEAN_STACK was enabled + -- Simon Johnson proposed I do a fully automated test suite. Hence "testme.sh" was born + -- Added LTC_NO_TEST which forces test vectors off (regardless of what tomcrypt_custom.h has) + -- Added LTC_NO_TABLES which disables large tables (where possible, regardless of what tomcrypt_custom.h has) + -- New test script found a bug in twofish.c when TABLES was disabled. Yeah testing! + -- Added a LTC_FAST specific test to the testing software. + -- Updated test driver to actually halt on errors and just print them out (useful for say... automated testing...) + -- Added bounds checking to Pelican MAC + -- Added BIT and OCTET STRING to the ASN.1 side of things. + -- Pekka Riikonen pointed out that my ctr_start() function should accept the counter mode. + -- Cleaned up warnings in testprof + -- Removed redundant mu and point mapping in ecc_verify_hash() so it should be a bit faster now + -- Pekka pointed out that the AES key structure was using 32 bytes more than it ought to. + -- Added quick defines to remove entire classes of algorithms. This makes it easier if you want to build with just + one algorithm (say AES or SHA-256). Defines are LTC_NO_CIPHERS, LTC_NO_MODES, LTC_NO_HASHES, LTC_NO_MACS, + LTC_NO_PRNGS, LTC_NO_PK, LTC_NO_PKCS + -- As part of the move for ECC to X9.62 I've changed the signature algorithm to EC DSA. No API changes. + -- Pekka helped me clean up the PKCS #1 v2.1 [OAEP/PSS] code + -- Wrote new DER SEQUENCE coder/decoder + -- RSA, DSA and ECDSA now use the DER SEQUENCE code (saves a lot of code!) + -- DSA output is now a DER SEQUENCE (so not compatible with previous releases). + -- Added Technote #5 which shows how to build LTC on an AMD64 to have a variety of algorithms in only ~80KB of code. + -- Changed temp variable in LOAD/STORE macros to "ulong32" for 32-bit ops. Makes it safer on Big endian platforms + -- Added INSTALL_GROUP and INSTALL_USER which you can specify on the build to override the default USER/GROUP the library + is to be installed as + -- Removed "testprof" from the default build. + -- Added IA5, NULL and Object Identifier to the list of ASN.1 DER supported types + -- The "no_oops" target (part of zipup) now scans for non-cvs files. This helps prevent temp/scratch files from appearing in releases ;-) + -- Added DERs for missing hashes, but just the OID not the PKCS #1 v1.5 additions. + -- Removed PKCS #1 v1.5 from the tree since it's taking up space and you ought to use v2.1 anyways + -- Kevin Kenny pointed out a few stray // comments + -- INTEGER code properly supports negatives and zero padding [Pekka!] + -- Sorted asn1/der/ directory ... less of a mess now ;-) + -- Added PRINTABLE STRING type + -- Removed ECC-160 as it wasn't a standard curve + -- Made ecc_shared_secret() ANSI X9.63 compliant + -- Changed "printf" to "fprintf(stderr, " in the testbench... ;-) + -- Optimized the GCM table creation. On 1KB packets [with key switching] the new GCM is 12.7x faster than before. + -- Changed OID representation for hashes to be just a list of unsigned longs (so you can compare against them nicely after decoding a sequence) + -- ECC code now uses Montgomery reduction ... it's even faster [ECC-256 make key down from 37.4M to 4.6M cycles on an Athlon64] + -- Added SHORT_INTEGER so users can easily store DER encoded INTEGER types without using the bignum math library + -- Fixed OMAC code so that with LTC_FAST it doesn't require that LTC_FAST_TYPE divides 16 [it has to divide the block size instead] + -- ECC key export is now a simple [and documented] SEQUENCE, the "encrypt_key" also uses a new SEQUENCE format. + -- Thanks goes to the following testers + Michael Brown - Solaris 10/uSPARCII + Richard Outerbridge - MacOS + Martin Carpenter - Solaris 8/uSPARCII [Thanks for cleaning up the scripts] + Greg Rose - ...
