/**
* 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
*
