this is the original DES specification: https://csrc.nist.gov/CSRC/media/Public ... ps46-3.pdf,
but it was withdrawn on May 19, 2005, for related information, you can see:
(1) Special Publication 800-131A, Transitions: Recommendations for Transitioning the Use of Cryptographic Algorithms and Key Lengths,
http://csrc.nist.gov/publications/PubsSPs.html#800-131A
(2) Special Publication 800-67 Rev. 1,Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher,
http://csrc.nist.gov/publications/PubsSPs.html#800-67
