/**
 * An SSL/TLS CipherSuite. Constants for the standard key exchange, cipher,
 * and mac algorithms are also defined in this class.
 *
 * The CipherSuite class and the inner classes defined in this file roughly
 * follow the type safe enum pattern described in Effective Java. This means:
 *
 *  . instances are immutable, classes are final
 *
 *  . there is a unique instance of every value, i.e. there are never two
 *    instances representing the same CipherSuite, etc. This means equality
 *    tests can be performed using == instead of equals() (although that works
 *    as well). [A minor exception are *unsupported* CipherSuites read from a
 *    handshake message, but this is usually irrelevant]
 *
 *  . instances are obtained using the static valueOf() factory methods.
 *
 *  . properties are defined as final variables and made available as
 *    package private variables without method accessors
 *
 *  . if the member variable allowed is false, the given algorithm is either
 *    unavailable or disabled at compile time
 *
