2011-06-13Fixed a pkcs#1 v1.5 flaw regarding leading zero bytesWerner Koch1-1/+3
With these changes the entire new pkcs#1 test suite passes fine. The leading zero bytes used to appear due to mixed signed/unsigned use of our internal representation of the values as MPIs. The changed code also detected another bug in the DSA selftest which used the pkcs1 flag - this was certainly wrong but didn't throw an error. The code in GnuPG does the right thing thus I believe not too many applications got it as wrong as we in our own selftest.

2011-04-11CTR mode may now be used with arbitrary long data chunks.Werner Koch1-0/+2
2011-03-09New function gcry_kdf_deriveWerner Koch1-0/+4
This allows us to factor the S2k code from gpg and gpg-agent out to libgcrypt. Created a bunch of test vectors using a hacked gpg 1.4. The function also implements PBKDF2; tested against the RFC-6070 test vectors.
2011-02-22Use AES-NI insns for CTR mode.Werner Koch1-4/+7
That really boosts the performance of CTR.

2011-02-17Flag the _ac_ functions as deprecated.Werner Koch1-0/+10
The AC functions are deprecated for a long time. How we will even print a warning if they are used. The module register interface is now also deprecated and the use of those functions will yield a warning as well.
2011-02-16Add GCRYCTL_DISABLE_HWFWerner Koch1-0/+1
This option is useful to disable detected hardware features. It has been implemented in benchmark, so that it is now possible to run tests/benchmark --disable-hwf intel-aesni cipher aes aes192 aes256 to compare the use of AES-NI insns to the pure C code.
2011-02-13First take on using AES-NI instructionsWerner Koch1-0/+2
This first naive use of the new Intel AES-NI instructions boosts the performance of AES on CPUs supporting this by 3 to 5 times. Results from running ./benchmark --cipher-repetitions 10 --large-buffers cipher aes on a cpu family : 6 model : 37 model name : Intel(R) Core(TM) i5 CPU 660 @ 3.33GHz stepping : 2 cpu MHz : 3325.494 cache size : 4096 KB cpu cores : 2 yields this: ECB/Stream CBC CFB OFB CTR --------------- --------------- --------------- --------------- --------------- 130ms 110ms 110ms 100ms 110ms 110ms 160ms 150ms 170ms 170ms 40ms 40ms 20ms 30ms 30ms 20ms 70ms 70ms 80ms 80ms The first line is with runtime switched off AES-NI instructions (don't set use_aesni in do_setkey), the second with enabled AES-NI. By fixing the alignment, I hope to squeeze out a little more even with this naive implementation.
2011-02-04Nuked almost all trailing whitespace.Werner Koch1-12/+12
Check and install the standard git pre-commit hook.
2011-02-01Add function gcry_pk_get_param.Werner Koch1-2/+3
Also changed quite some trailing white spaces. I never configured that in Emacs but git diff annoys me with red lines and thus it seems better to use nuke-trailing-whitespace autmatically. Sorry for the extra diff lines. A diff filter should help to not show those changes.
