ascon128_masked_aead_decrypt()

int ascon128_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_128_t *	k
	)

Decrypts and authenticates a packet with masked ASCON-128.

Parameters

m	Buffer to receive the plaintext message on output.
mlen	Receives the length of the plaintext message on output.
c	Buffer that contains the ciphertext and authentication tag to decrypt.
clen	Length of the input data in bytes, which includes the ciphertext and the 16 byte authentication tag.
ad	Buffer that contains associated data to authenticate along with the packet but which does not need to be encrypted.
adlen	Length of the associated data in bytes.
npub	Points to the public nonce for the packet which must be 16 bytes in length.
k	Points to the masked 128-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.
