Cryptic Disk provides a simple and affordable way to protect disks and disk partitions by encrypting them. The encrypted data cannot be accessed without entering the password, even if a hacker gets access to a PC or the hard drive is stolen. The program uses the AES 256-bit encryption algorithm, the same type of encryption that NASA, the FBI and the Department of Defense use to protect their data. Encrypting and decrypting takes one click and does not require a PhD in mathematics or computer science. Cryptic Disk can be used either at home or in the office. The program supports multiple users with different degrees of access privileges, as set by the system administrator. Each user will then have access to the encrypted data that he or she has the access rights to, but not to the data of others.
