NAME
gnutls_cipher_encrypt3 - API function
SYNOPSIS
#include <gnutls/crypto.h>
int gnutls_cipher_encrypt3(gnutls_cipher_hd_t handle, const void *
ptext, size_t ptext_len, void * ctext, size_t * ctext_len, unsigned
flags);
ARGUMENTS
gnutls_cipher_hd_t handle
is a gnutls_cipher_hd_t type
const void * ptext
the data to encrypt
size_t ptext_len
the length of data to encrypt
void * ctext
the encrypted data
size_t * ctext_len
the length of encrypted data (initially must hold the maxi-
mum available size)
unsigned flags
flags for padding
DESCRIPTION
This function will encrypt the given data using the algorithm specified
by the context. For block ciphers, ptext_len is typically a multiple of
the block size. If not, the caller can instruct the function to pad the
last block according to flags . Currently, the only available padding
scheme is GNUTLS_CIPHER_PADDING_PKCS7.
If ctext is not NULL, it must hold enough space to store resulting ci-
pher text. To check the required size, this function can be called with
ctext set to NULL. Then ctext_len will be updated without performing
actual encryption.
RETURNS
Zero or a negative error code on error.

3.7.7
