10
11       int  gnutls_aead_cipher_encrypt(gnutls_aead_cipher_hd_t  handle,  const
12       void * nonce, size_t nonce_len, const void  *  auth,  size_t  auth_len,

14       size_t * ctext_len);
15

ARGUMENTS

17       gnutls_aead_cipher_hd_t handle
18                   is a gnutls_aead_cipher_hd_t type.
19
20       const void * nonce
21                   the nonce to set
22
23       size_t nonce_len
24                   The length of the nonce
25
26       const void * auth
27                   additional data to be authenticated
28
29       size_t auth_len
30                   The length of the data
31
32       size_t tag_size
33                   The size of the tag to use (use zero for the default)
34
35       const void * ptext
36                   the data to encrypt
37
38       size_t ptext_len
39                   The length of data to encrypt
40
41       void * ctext
42                   the encrypted data including authentication tag
43
44       size_t * ctext_len
45                   the length of encrypted data (initially must hold the maxi‐
46                   mum available size, including space for tag)
47
