+ * @defgroup Algos Cryptographic Algorithms
+ *
+ *
+ * This library provides several different cryptographic algorithms,
+ * each of which can be selected by using the cipher_type_id_t and
+ * auth_type_id_t.  These algorithms are documented below.
+ *
+ * Authentication functions that use the Universal Security Transform
+ * (UST) must be used in conjunction with a cipher other than the null
+ * cipher.  These functions require a per-message pseudorandom input
+ * that is generated by the cipher.
+ * 
+ * The identifiers STRONGHOLD_AUTH and STRONGHOLD_CIPHER identify the
+ * strongest available authentication function and cipher,
+ * respectively.  They are resolved at compile time to the strongest
+ * available algorithm.  The stronghold algorithms can serve as did
+ * the keep of a medieval fortification; they provide the strongest
+ * defense (or the last refuge).
