!!! Overview
[{$pagename}]  is a [Symmetric Key] [Block Cipher], designed in [1993|Year 1993] by [Bruce Schneier] and included in a large number of cipher suites and [encryption] products. 

[{$pagename}] provides a good encryption rate in software and no effective cryptanalysis of it has been found to date. However, the [Advanced Encryption Standard] ([AES]) now receives more attention.

[{$pagename}] was designed as a general-purpose algorithm, intended as an alternative to the aging [DES] and free of the problems and constraints associated with other algorithms. At the time Blowfish was released, many other designs were proprietary, encumbered by patents or were commercial or government secrets. [Bruce 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."[citation needed]

Notable features of the design include key-dependent S-boxes and a highly complex key schedule.

However, the [Advanced Encryption Standard] ([AES]) now receives more attention.
