Hello everyone
I am using Crypt::CBC module
I have written two programs 1 is for crypting string
Other is for decrypting into string


CBC encryption code
#!/usr/bin/perl use Crypt::CBC; my $cipher = Crypt::CBC->new( -key => '1234Ffg!7645', -cipher => 'Blowfish' ); $plaintext = $ARGV[0]; $ciphertext = $cipher->encrypt($plaintext); $ciphertext = unpack("H16",$ciphertext); print "$ciphertext\n";

CBC Decryption code
#!/usr/bin/perl use Crypt::CBC; my $cipher = Crypt::CBC->new( -key => '1234Ffg!7645', -cipher => 'Blowfish' ); $ciphertext = pack("H16",$ARGV[0]); $plaintext = $cipher->decrypt($ciphertext); print "$plaintext\n";
Execution of programs
. 1) cryptCBC.pl "This is CBC"
output == 53616c7465645f5f
2) cryptCBC_dc.pl 53616c7465645f5f
Ciphertext does not begin with a valid header for 'salt' header mode at cryptCBC_dc.pl line 9
can any explain me about the error .....
