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
maximum 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 cipher 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.
SINCE
3.7.7
