PHP Encryption

[Anon]

Hi, All.
We have an existing perl application which encrypts data into hex string using Crypt::CBC, DES.
I am wondering if I can use php to decrypt the data that are passed along though URL. Below is my perl code:

use Crypt::CBC;
my $cypher = new Crypt::CBC("Secret Key", "DES");
my $text = "How are you doing?";
$enc_text = $cypher->encrypt_hex($text);
$text = $cypher->decrypt_hex($enc_text);

For example, the $enc_text might be sth like:
52616e646f6d4956df1e2f07c9d53
I want to pass this to php and have it decrypt it back into "How are you doing?"

Any idea?
Thanks.

manuals are your friend:

Or you might want to reimplement the DES algorithm in PHP. I'm almost sure it has already been done. RC4 and some others are available.

Use mcrypt:

http://www.php.net/mcrypt-cbc

$text = mcrypt_cbc(MCRYPT_DES, "Secret Ket", $enc_text, MCRYPT_DECRYPT);

And you are done. Just remember that you will probably have to compile mcrypt and mcrypt support into php.

hope that helps!
