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.

What is the difference between Obfuscation, Hashing, and Encryption?
Here is my understanding:
Hashing is a one-way algorithm; cannot be reversed Obfuscation is similar to encryption but doesn't require any "secret" to understand (ROT13 is one example...

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.

The SHA-256 hash function is a hash function , it is not bijective .
Hi use the Mcrypt module instead.
If you need to be able to encrypt and decrypt information, read up on the mcrypt functions.
