Crypt::GOST_PP - Pure Perl implementation of the GOST encryption algorithm
use Crypt::GOST_PP;
$ref = Crypt::GOST_PP->new( $passphrase );
$encrypted = $ref->encrypt( $plaintext );
$ref2 = Crypt::GOST_PP->new( $passphrase );
$decrypted = $ref2->decrypt( $encrypted );
GOST is a 64-bit symmectric block cipher with a 256-bit key, from the former
Soviet Union.
It is important to note that there are (or have been) several
other GOST encryption modules for perl. This version is in no way intended
to supersede any other such implementations, specifically Crypt::GOST. The
purpose for writing this module was that I do a great deal of work on Win32
systems, and I have been unsuccessful in my attempts to get Crypt::GOST to
install correctly in that environment. A previous version of Crypt::GOST,
v0.41, was also a pure perl implementation, but it lacked documentation, and
as such it was more difficult to use than one would prefer. As a result of
these two things, I wanted to write a pure perl implementation, with
requisite documentation, that will run regardless of the OS.
Much of the core logic of Crypt::GOST_PP was originally based on
Vipul Ved Prakash's "GOST in 417 bytes of Perl"
<http://www.vipul.net/gost/>. The code contained herein has undergone
numerous revisions and modifications since that original diminutive
implementation.
