/// <summary>
/// Blowfish is a keyed, symmetric block cipher, designed in 1993 by Bruce Schneier and included in a large
/// number of cipher suites and encryption products. Blowfish provides a good encryption rate in software and no
/// effective cryptanalysis of it has been found to date. However, the Advanced Encryption Standard now receives
/// more attention. Schneier designed Blowfish as a general-purpose algorithm, intended as an alternative to the
/// aging DES and free of the problems and constraints associated with other algorithms. Schneier has stated that,
/// "Blowfish is unpatented, and will remain so in all countries. The algorithm is hereby placed in the public
/// domain, and can be freely used by anyone." The implementation type in use is CFB64.
