The Data Encryption Standard (DES), also known as Data
|
|
Encryption Algorithm (DEA) is a semi-strong encryption and
|
|
decryption algorithm.
|
|
The module is 100 % compatible to Crypt::DES but is implemented
|
|
entirely in Perl. That means that you do not need a C compiler
|
|
to build and install this extension.
|
|
The module implements the Crypt::CBC interface. You are
|
|
encouraged to read the documentation for Crypt::CBC if you
|
|
intend to use this module for Cipher Block Chaining.
|
|
The minimum (and maximum) key size is 8 bytes. Shorter keys will
|
|
cause an exception, longer keys will get silently truncated.
|
|
Data is encrypted and decrypted in blocks of 8 bytes.
|
|
The module implements the Ultra-Fast-Crypt (UFC) algorithm as
|
|
found for example in the GNU libc. On the Perl side a lot has
|
|
been done in order to make the module as fast as possible
|
|
(function inlining, use integer, ...).
|
|
Note: For performance issues the source code for the module is
|
|
first preprocessed by m4. That means that you need an m4 macro
|
|
processor in order to hack on the sources. This is of no concern
|
|
for you if you only want to use the module, the preprocessed
|
|
output is always included in the distribution.
