Currently there are no functions in a default build of PHP to carry out two way encryption, there is the mcrypt extension but it is not build in PHP by default. Secrypt is a class written in PHP to fill that gap and allow secure, customizable and most importantly, understandable two way encryption for PHP. If you have the zlib extension your data can be compressed/decompressed.

This class can be used to hide encrypted data in images using steganography which is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message. It reads a given image in GIF, JPEG or PNG formats, encrypts data supplied by the user (a message, a file, a collection of both) and hides the encrypted data in the image by making subtle colour changes to certain pixels to store the data in the image symbolically. The resulting image is generated in PNG format (because PNG is lossless). The advantage of steganography over cryptography alone is that messages do not attract attention to themselves, to messengers, or to recipients. An unhidden coded message, no matter how unbreakable it is, will arouse suspicion and may in itself be incriminating, as in some countries encryption is illegal.

You can generate a password of any length, and decide if want or not to use uppercase, lowercase, numbers or any special character. Plug and play funcion.

Scripthash is a PHP extention which enables you securely hide passwords or execute programs as a different user when using PHP as an Apache Module or as a RedHat RPM. During module initialization a shared memory segment is created and initialised with a randomly generated secret. This segment remains attached across the subsequent forks which create the Apache children and thus the children have access to the secret. The module implements a single function scripthash() which when called returns an MD5 hash of the secret and various attributes of the call. This hash can be used by external programs to securely return privileged information to the caller.
