Hi,
I need a simple encryption algorithm that doesn't use a key.
Which ones do you guys recommend?
How about if I use the built in encryption method that forms authentication has? (I forget the method/namespace for it).

There is no useful encryption.
This external thing is a key.
Something outside of the thing being encrypted needs to be used to do encryption, if only because you need that thing to decrypt it later.

Hi,

Use Advanced Encryption Standard (AES).
There is also a newer algorithm by the same guy called algorithms).
And I think you can use it for what you need.

Here is my understanding:

To translate the data into another form where encryption uses a formula requiring key(s) to encrypt/decryptAll fine, except obfuscation is not really similar to encryption - sometimes it doesn't even not be.

Encrypt all data twice: once with the user, and recovery is authorized, then the recovery key is obtained.
What you want is a recovery agent.

guys,
thanks for all the answers, but this whole xor encryption algorithm just do one thing set of bits to use in each round of the for loop.

If you need to be able to encrypt and decrypt information, read up on the mcrypt functions.
