DriveCryptPlusPack 1.0c (Shareware, $149.95)

DCPP allows you to secure your disk(s)(including removable media) with a powerful and proven encryption algorithm(AES-256) at the sector level, ensuring that only authorized users access it. The encryption algorithm is a trusted,validated algorithm chosen by the National Institute of Standards and Technology(NIST) and slated to be the cryptographic standard for years to come. AES-256 is a FIPS-approved symmetric encryption algorithm that may be used by U.S.Government organizations(and others) to protect sensitive information.DCPP is automatic and completely transparent to the user.Not only does this decrease user involvement and training requirements, but it creates the foundation for enforceable security. The careful integration of boot protection and automatic encryption provides a high degree of security with minimal impact on users. Boot protection prevents subversion of the operating system (via floppy bootup, for example) or the introduction of rogue programs while sector by sector encryption makes it i

StrongDisk Pro 3.0 (Shareware, $89.95)

StrongDisk Pro protects sensitive data on your notebook or PC. It creates virtual encrypted disks, which work as common disks. All content of these disks is encrypting on-the-fly with strong crypto-algorithms. To mount disk a password and an external key is required. Any files, documents and databases can be kept on and opened directly from encrypted disks. The content of disk is physically stored in a common file. Thus backup can be made easily. You may store this file on hard disk, floppy, CD or any other location.
