◆ ascon80pq_masked_aead_decrypt()

int ascon80pq_masked_aead_decrypt ( unsigned char *  m,
size_t *  mlen,
const unsigned char *  c,
size_t  clen,
const unsigned char *  ad,
size_t  adlen,
const unsigned char *  npub,
const ascon_masked_key_160_t k 
)

Decrypts and authenticates a packet with masked ASCON-80pq.

Parameters
mBuffer to receive the plaintext message on output.
mlenReceives the length of the plaintext message on output.
cBuffer that contains the ciphertext and authentication tag to decrypt.
clenLength of the input data in bytes, which includes the ciphertext and the 16 byte authentication tag.
adBuffer that contains associated data to authenticate along with the packet but which does not need to be encrypted.
adlenLength of the associated data in bytes.
npubPoints to the public nonce for the packet which must be 16 bytes in length.
kPoints to the masked 160-bit key.
Returns
0 on success, -1 if the authentication tag was incorrect, or some other negative number if there was an error in the parameters.
