NAME

       gnutls_aead_cipher_encrypt - API function

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.
