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
                   additional 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 including authentication tag

       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.

RETURNS
       Zero or a negative error code on error.

SINCE
       3.4.0
