Cipherlok is a data security product that provides easy to use yet highly secure encryption of files on your PC or notebook. Once files have been encrypted using Cipherlok's Blowfish algorithm and 160 bit key it is virtually impossible to crack the security. Cipherlok can work either with traditional passphrases or Cipherlok USB Tokens. Cipherlok adds functions to encrypt, decrypt and secure delete to the right click menu of Windows Explorer allowing files or folders to be encrypted in just two mouse clicks. Also AutoCipher, a system tray utility, can automatically decrypt user defined files at startup and ensure they are encrypted at shutdown. This product contains the Cipherok software only.
