  FIPS 46-2 - (DES), Data Encryption Standard
Data that is considered sensitive by the responsible authority, data that has a high value, or data that represents a high value should be cryptographically protected if it is vulnerable to unauthorized disclosure or undetected modification during transmission or while in storage.
The algorithm is designed to encipher and decipher blocks of data consisting of 64 bits under control of a 64-bit key.** Deciphering must be accomplished by using the same key as for enciphering, but with the schedule of addressing the key bits altered so that the deciphering process is the reverse of the enciphering process.
Protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data.

 Data Security File Encryption and Audit Software
R-Guard 2.2 is a reliable data security tool for advanced access right control, encryption and audit, which extends them much beyond the scope of the standard Windows security services.
Such protection level cannot be achieved by the standard Windows security services because they control access to files basing on the user's access rights, which the trojan can easily obtain, whereas R-Guard controls the access rights individually for each program.
R-Guard's easy-to-use, but uncrackable Data Encryption System encrypts file objects and keeps them encrypted on any hard disk regardless of the file system including FAT and even on a virtual hard drive on a remote file server.

 Brute Force: Cracking the Data Encryption Standard — Ergo Sum
Brute Force: Cracking the Data Encryption Standard is the story of how the global standard for data encryption was broken by a group of hobbyists, cryptographers, and civil libertarians in 1997, even as Congress debated whether to relax or to increase restrictions on the use of cryptography by American companies and private citizens.
The book is worthy in showing some of the personalities involved in this struggle...It puts flesh on what are otherwise often just journal papers describing breakthroughs, but which often give little information about what it takes in people to discover or invent such things.
John Gilmore has a recording of Whitfield Diffie and Martin Hellman arguing the need for a larger key in the data encryption standard and has made it available online.
