+ * @brief Represent a cryptographic suite, a set of corresponding hash and signing/MAC/CRC algorithms.
+ *
+ * A cryptographic suite encapsulates the method by which (public key) digital signatures and
+ * (private key) MACs. For example, a digital signature suite might combine SHA-256 as the hash
+ * digest algorithm and RSA as the signature generation/verification algorithm. Such a suite
+ * would would have the PARCCryptoSuite value PARCCryptoSuite_RSA_SHA256.
