Crypt::TripleDES
NAME Crypt::TripleDES - Triple DES encyption. SYNOPSIS my $des = new Crypt::TripleDES; my $cyphertext = $des->encrypt3 ( $plaintext, $passphrase ); my $plaintext = $des->decrypt3 ( $cyphertext, $passphrase ); DESCRIPTION This module implements 3DES encryption in ECB mode. The code is based on Eric Young's implementation of DES in pure perl. It's quite slow because of the way Perl handles bit opera
