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)


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