gnutls_cipher_decrypt2 - API function
#include <gnutls/crypto.h>
int gnutls_cipher_decrypt2(gnutls_cipher_hd_t handle, const void *
ctext, size_t ctext_len, void * ptext, size_t ptext_len);
gnutls_cipher_hd_t handle
is a gnutls_cipher_hd_t type
const void * ctext
the data to decrypt
size_t ctext_len
the length of data to decrypt
void * ptext
the decrypted data
size_t ptext_len
the available length for decrypted data
This function will decrypt the given data using the algorithm
specified by the context. For block ciphers the ctext_len must be a
multiple of the block size. For the supported ciphers the plaintext
data length will equal the ciphertext size.
Note that in AEAD ciphers, this will not check the tag. You will need
to compare the tag sent with the value returned from
gnutls_cipher_tag().
Zero or a negative error code on error.
