94 of gcc (bug reported by David Barrett)
95 * Correctly handle the case in padlock_xcryptcbc() when input or
96 ouput data is non-aligned by falling back to the software
97 implementation, as VIA Nehemiah cannot handle non-aligned buffers

114 peer may cause xyssl to loop indefinitely by sending a certificate
115 for which the RSA signature check fails (bug reported by Benoit)
116 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
117 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
