NAME
Crypt::Cipher::RC2 - Symmetric cipher RC2, key size: 40-1024 bits
SYNOPSIS
### example 1 use Crypt::Mode::CBC; my $key = '...'; # length has to be valid key size for this cipher my $iv = '...'; # 16 bytes my $cbc = Crypt::Mode::CBC->new('RC2'); my $ciphertext = $cbc->encrypt("secret data", $key, $iv); ### example 2 (slower) use Crypt::CBC; use Crypt::Cipher::RC2; my $key = '...'; # length has to be valid key size for this cipher my $iv = '...'; # 16 bytes my $cbc = Crypt::CBC->new( -cipher=>'Cipher::RC2', -key=>$key, -iv=>$iv ); my $ciphertext = $cbc->encrypt("secret data");
DESCRIPTION
This module implements the RC2 cipher. Provided interface is compliant with Crypt::CBC module.
BEWARE: This module implements just elementary "one-block-(en|de)cryption" operation - if you want to encrypt/decrypt generic data you have to use some of the cipher block modes - check for example Crypt::Mode::CBC, Crypt::Mode::CTR or Crypt::CBC (which will be slower).
METHODS
new
$c = Crypt::Cipher::RC2->new($key); #or $c = Crypt::Cipher::RC2->new($key, $rounds);
