Hi there,
I would like to encrypt some info and later be able to decrypt it. As I saw there is only one way encryption possible with encrypt.
Has anybody an idea how to do a 2 way encrypten?
Thank you for any help,

Hi,
that requires to install another module?! It does not have to be that
secure. Is there an easier way to encrypt an 8 digit ID without going through the
hastle of updating the system? That sounds like a standard function to me.
There are pure software solutions available. There was a 3 kb class included with Horde for instance, which could be used very nicely. It was called HCEMD5 and could do encryption/decryption with a secret and a public key (which were simple strings).
You can also look in pear.php.net and see if any packages are good for you. I think this may do what you want: http://pear.php.net/package/Crypt_RC4
You can use PEAR packages without needing a priviledged user to install them on the server.
Hi, I tryed the Pear package, and it encryptes well. However the encrypten is not URL friendly. My goal is to encrypt a 8 digit ID into a URL. Can this be that hard?`I bet there are hundreds of people wanting to make a similar encrypten with php.
