In this article I will explain how to create a PHP Class that will encrypt and decrypt any data with a given password. It is object programmed and uses existing PHP algorithms.
Excerpt :
Think about what we might need a class like this for? We want to encrypt important data with a password for security reasons. We also want, as already mentioned, to be able to decrypt that data when necessary. Why should you use symmetric algorithms? It’s easy; when you’re offering a password sent via email or something like that, you need the password to be sent in plaintext. The hash algorithms are not reversible. Once you have hashed a string you can’t decipher the original text from the hash.
