This is not about security. It is also not to make it hard to break. I'm looking for a simple algorithm to change a string (a url) in a way it does not resemble the original. The encryption will be done with javascript. Then I want to feed the encrypted string to a PHP function to change it back to the original. Both ends could share a secret key, or the conversions could be key-less and rely on just logic.The ideal solution[*]will be simple[*]will use available javascript functions for encryption[*]will use available php functions for decryption[*]will produce encrypted string in way not to resemble the plain text at all[*]will only use lower-case alphabet characters and numbers in the encrypted string[*]is not a method widely used like Base64-ing as encryption.Edit: The last requirement was added after shamittomar's answer.
