    * Correctly handle the case in padlock_xcryptcbc() when input or
      ouput data is non-aligned by falling back to the software
      implementation, as VIA Nehemiah cannot handle non-aligned buffers

      Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to

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