Expand description

AES-GCM decryption.

  • pt - Plaintext.
  • tag - Authentication tag.
  • tag_len - Authentication tag length, 0 < * tag_len - <= 16.
  • ct - Ciphertext.
  • ct_len - Ciphertext length, 0 < * ct_len - < 2^36-32 bytes.
  • key - AES key.
  • size - Key size (16, 24, or 32 bytes).
  • iv - Initial vector.
  • aa - Additional authentication data.
  • aa_len - Additional authentication data length, 0 < * aa_len - < 2^61 bytes.

@remark * ct - may be same as * pt - .

Returns 0 If * tag - is valid. Returns -1 Otherwise.
