NAME         top

       gnutls_aead_cipher_encrypt - API function

SYNOPSIS         top

       #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         top

       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         top
