SYNOPSIS
#include <gnutls/crypto.h>int gnutls_aead_cipher_encrypt(gnutls_aead_cipher_hd_t handle, const void * nonce, size_t nonce_len, const void * auth, size_t auth_len, size_t tag_size, const void * ptext, size_t ptext_len, void * ctext, size_t * ctext_len);
ARGUMENTS
- gnutls_aead_cipher_hd_t handle
- is a gnutls_aead_cipher_hd_t type.
- const void * nonce
- the nonce to set
- size_t nonce_len
- The length of the nonce
- const void * auth
- the data to be authenticated
- size_t auth_len
- The length of the data
- size_t tag_size
- The size of the tag to use (use zero for the default)
- 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, including space for tag)
DESCRIPTION
This function will encrypt the given data using the algorithm specified by the context. The output data will contain the authentication tag. This function requires that gnutls_aead_cipher_set_nonce() is called before it.RETURNS
Zero or a negative error code on error.SINCE
