NAME Crypt::TripleDES::CBC - Triple DES in CBC mode Pure implementation VERSION version 0.004 SYNOPSIS use Crypt::TripleDES::CBC; my $key = pack("H*" , "1234567890123456" . "7890123456789012"); my $iv = pack("H*","0000000000000000"); my $crypt = Crypt::TripleDES::CBC->new( key => $key, iv => $iv, ); say unpack("H*",$crypt->encrypt(pack("H*","0ABC0F2241535345631FCE"))); # Output F64F2268BF6185A16DADEFD7378E5CE5 say unpack("H*",$crypt->decrypt(pack("H*","F64F2268BF6185A16DADEFD7378E5CE5"))); # Output 0ABC0F2241535345631FCE0000000000 DESCRIPTION Most Modules on CPAN don't do a standards compliant implementation, while they are able to decrypt what they encrypt. There are corner cases where certain blocks of data in a chain don't decrypt properly. This is (almost)a pure perl implementation of TripleDES in CBC mode using Crypt::DES to encrypt individual blocks. ATTRIBUTES cipher1 First Crypt::DES Cipher object generated from the key. This is built automatically. Do not change this value from your program. cipher2 second Crypt::DES Cipher object generated from the key. This is built automatically. Do not change this value from your program. key Encryption Key this must be ascii packed string as shown in Synopsis. iv Initialization vector, default is a null string.
