Manuel Pégourié-Gonnard ea499a7321 Add support for secp192k1 2014-01-17 21:41:39 +01:00
Manuel Pégourié-Gonnard 0a56c2c698 Fix bug in ecdh_calc_secret() 
Only affects curves with nbits != pbits (currently only secp224k1)

Manuel Pégourié-Gonnard 5304812b2d Fix theoretical compliance issue in ECDSA 
The issue would happen for curves whose bitlength is not a multiple of eight
(the only case is NIST P-521) with hashes that are longer than the bitlength
of the curve: since the wides hash is 512 bits long, this can't happen.
Fixing however as a matter of principle and readability.

Paul Bakker 956c9e063d Reduced the input / output overhead with 200+ bytes and covered corner 
case

The actual input / output buffer overhead is only 301 instead of 512.
This requires a proper check on the padding_idx to prevent out of bounds
reads.

Previously a remote party could potentially trigger an access error and
thus stop the application when sending a malicious packet having
MAX_CONTENT_LEN of data, 32 bytes of MAC and a decrypted padlen of .
This would result in reading from in_ctr + 13 + 32 + MAX_CONTENT_LEN - 1 - 1
for 256 bytes (including fake padding check). Or 13 + 32 bytes over the
buffer length.

We now reset padding_idx to 0, if it's clear that it will never be a
valid padding (padlen > msg_len || msg_len + padlen + 256 > buffer_len)
