Expand description

AES-CCM decryption.

  • pt - Plaintext.
  • tag - Authentication tag.
  • tag_len - Tag length (4, 6, 8, 10, 12, 14, or 16).
  • ct - Ciphertext.
  • ct_len - Ciphertext length, 0 <= * ct_len - < 2^(8*(15-n_len)).
  • key - AES key.
  • size - Key size (16, 24, or 32).
  • nonce - Nonce.
  • n_len - Nonce length, 7 <= * n_len - <= 13.
  • aa - Additional authentication data.
  • aa_len - Additional authentication data length.

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

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