Expand description

AES-CBC-PKCS7 decryption.

  • pt - Plaintext.
  • pt_len - Plaintext length.
  • ct - Ciphertext.
  • ct_len - Ciphertext length. Must be a multiple of 16.
  • key - AES key.
  • size - Key size (16, 24, or 32).
  • iv - Initial vector.

Returns 0 If the input is properly padded. Returns -1 Otherwise.

@remark * pt - may be same as * ct - . @remark The maximum length of * pt - is * ct_len - - 1.
