Encrypt Data in Counter Mode The Crypt::Ctr module offers generic counter mode implementation in pure Perl. The Counter Mode module constructs a stream cipher from a block cipher or cryptographic hash funtion and returns it as an object.Any block cipher in the Crypt:: class can be used, as long as it supports the blocksize and keysize methods. Any hash function in the Digest:: class can be used, as long as it supports the add method.SYNOPSIS use Crypt::Ctr; my $cipher = new Crypt::Ctr $key, 'Crypt::Rijndael'; my $ciphertext = $cipher->encrypt($plaintext); my $plaintext = $cipher->decrypt($ciphertext); my $cipher2 = new Crypt::Ctr $key, 'Digest::MD5'; $ciphertext = $cipher->encrypt($plaintext); $plaintext = $cipher->decrypt($ciphertext); Requirements: · Perl
