@var{handle}: is a @code{gnutls_aead_cipher_hd_t}  type.

@var{nonce}: the nonce to set

@var{nonce_len}: The length of the nonce

@var{auth_iov}: additional data to be authenticated

@var{auth_iovcnt}: The number of buffers in  @code{auth_iov} 

@var{tag_size}: The size of the tag to use (use zero for the default)

@var{iov}: the data to be encrypted

@var{iovcnt}: The number of buffers in  @code{iov} 

@var{ctext}: the encrypted data including authentication tag

@var{ctext_len}: the length of encrypted data (initially must hold the maximum available size, including space for tag)

This function will encrypt the provided data buffers using the algorithm
specified by the context. The output data will contain the
authentication tag.

@strong{Returns:} Zero or a negative error code on error.

@strong{Since:} 3.6.3
