+/**
+ * Key Conversion, primarily "Base64"
+ *
+ * Base64 is required for "Basic Authorization", which is an important part of the overall CADI Package.
+ *
+ * Note: This author found that there is not a "standard" library for Base64 conversion within Java.
+ * The source code implementations available elsewhere were surprisingly inefficient, requiring, for
+ * instance, multiple string creation, on a transaction pass. Integrating other packages that might be
+ * efficient enough would put undue Jar File Dependencies given this Framework should have none-but-Java
+ * dependencies.
+ *
+ * The essential algorithm is good for a symmetrical key system, as Base64 is really just
+ * a symmetrical key that everyone knows the values.
+ *
+ * This code is quite fast, taking about .016 ms for encrypting, decrypting and even .08 for key
+ * generation. The speed quality, especially of key generation makes this a candidate for a short term token
+ * used for identity.
+ *
+ * It may be used to easily avoid placing Clear-Text passwords in configurations, etc. and contains
+ * supporting functions such as 2048 keyfile generation (see keygen). This keyfile should, of course,
+ * be set to "400" (Unix) and protected as any other mechanism requires.
+ *
+ * However, this algorithm has not been tested against hackers. Until such a time, utilize more tested
+ * packages to protect Data, especially sensitive data at rest (long term).
