**const gnutls\_cipher\_algorithm\_t * gnutls\_cipher\_list( void);**

# [ARGUMENTS](#ARGUMENTS)

[void](#void)

# [DESCRIPTION](#DESCRIPTION)

Get a list of supported cipher algorithms. Note that not necessarily all ciphers are supported as TLS cipher suites. For example, DES is not supported as a cipher suite, but is supported for other purposes (e.g., PKCS**8** or similar).

This function is not thread safe.

# [RETURNS](#RETURNS)

a (0)-terminated list of **gnutls\_cipher\_algorithm\_t** integers indicating the available ciphers.
