Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. It does *not* require the mcrypt extension, or any other extention be compiled into PHP, it uses 100% PHP, and is fully FIPS 197 Compliant. AES uses a transformation schema, where it first using a substitution table, then shifts data rows, then mixes columns to finally do a simple XOR. aes-256-cbc is the encryption cipher to be used. The attached java files have AES 256 algorithm with some modifications. Encrypt any plain string value (text) For encryption or decryption you need to know only "salt" other words - password or passphrase After encryption you will see base64 encoded string as output, so you may safely send it to someone who already know the password, or send a link (use "store" option) to encrypted text. The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. Everyone should have stopped using the PHP Mcrypt extension for new work already and should be planning to move their existing apps off it too because libmcrypt was abandoned in 2003 and is unmaintained.
