+/**
+ * gnutls_random_art:
+ * @type: The type of the random art (for now only %GNUTLS_RANDOM_ART_OPENSSH is supported)
+ * @key_type: The type of the key (RSA, DSA etc.)
+ * @key_size: The size of the key in bits
+ * @fpr: The fingerprint of the key
+ * @fpr_size: The size of the fingerprint
+ * @art: The returned random art
+ *
+ * This function will convert a given fingerprint to an "artistic"
+ * image. The returned image is allocated using gnutls_malloc(), is
+ * null-terminated but art->size will not account the terminating null.
+ *
+ * Returns: On success, %GNUTLS_E_SUCCESS (0) is returned, otherwise
+ *   an error code is returned.
