MCrypt replaces the old crypt() package and the crypt(1) command, with add-ons. MCrypt is a file encryption method. It uses secure techniques to exchange data. It enables users to encrypt files or data streams without the need for cryptography. It allows developers to use a wide range of encryption features, with no drastic changes to their code. It also gives a really neat code on your machine. 

Features of mcrypt

Some important features of mcrypt are:

  • Provides an algorithmic vulnerability.
  • Compression before encryption provides efficiency, faster encryption, and safety of data.
  • Error Recovery: The CFB mode used in MCrypt will retrieve deleted files from the file or stream in BCE, CBC, and OFB modes. MCrypt also utilizes a 32-bit CRC to verify errors in encrypted files.
  • It ensures that no important data are written to disk.
