-/**
- * A wrapper class for the most commonly used encoding and

- * and decoding input using base64, uu and the quoted-printable
- * specifications.
- *
- * \b Usage:
- *
- * \code
- * TQCString input = "Aladdin:open sesame";
- * TQCString result = KCodecs::base64Encode(input);
- * cout << "Result: " << result.data() << endl;
- * \endcode
- *
- * <pre>
- * Output should be
- * Result: QWxhZGRpbjpvcGVuIHNlc2FtZQ==
- * </pre>
- *
- * The above example makes use of the convenience functions
- * (ones that accept/return null-terminated strings) to encode/decode
- * a string. If what you need is to encode or decode binary data, then
- * it is highly recommended that you use the functions that take an input
- * and output TQByteArray as arguments. These functions are specifically
- * tailored for encoding and decoding binary data.

-/**
- * @short An adapted C++ implementation of RSA Data Securities MD5 algorithm.
- *
- * The default constructor is designed to provide much the same
- * functionality as the most commonly used C-implementation, while
- * the other three constructors are meant to further simplify the
- * process of obtaining a digest by calculating the result in a
- * single step.
- *
- * KMD5 is state-based, that means you can add new contents with
- * update() as long as you didn't request the digest value yet.
- * After the digest value was requested, the object is "finalized"
- * and you have to call reset() to be able to do another calculation
- * with it. The reason for this behavior is that upon requesting
- * the message digest KMD5 has to pad the received contents up to a
- * 64 byte boundary to calculate its value. After this operation it
- * is not possible to resume consuming data.
- *
- * \b Usage:
- *
- * A common usage of this class:
- *
- * \code
- * const char* test1;
- * KMD5::Digest rawResult;
- *
- * test1 = "This is a simple test.";
- * KMD5 context (test1);
- * cout << "Hex Digest output: " << context.hexDigest().data() << endl;
- * \endcode
- *
- * To cut down on the unnecessary overhead of creating multiple KMD5
- * objects, you can simply invoke reset() to reuse the same object
- * in making another calculation:
- *
- * \code
- * context.reset ();
- * context.update ("TWO");
- * context.update ("THREE");
- * cout << "Hex Digest output: " << context.hexDigest().data() << endl;
- * \endcode
