What is it all about?
MCrypt arrived instead the old Unix crypt and crypt(1) functions, with extensions. It offers developers to use a vrious of encryption application and commends such as AES(Advanced Encryption Standard), without making a significant change to their code.
* It allows developers to use a wide range of encryption functions, without making drastic changes to their code. * It allows users to encrypt files or data streams without having to be cryptographers. * It allows you to have some really neat code on your machine. * The companion to MCrypt is Libmcrypt, which contains the actual encryption functions themselves, and provides a standardized mechanism for accessing them.
