  • July 3, 2019: NIST invites comments on Draft NIST Special Publication (SP) 800-175B Revision 1, Guideline for Using Cryptographic Standards in the Federal Government: Cryptographic Mechanisms, which is part of a series of documents that provides recommendations for protecting sensitive, unclassified digitized information using cryptography and NIST’s cryptographic standards. The document discusses cryptographic methods and services and refers to the recently published strategy for deprecating the Triple Data Encryption Algorithm (TDEA). Additional changes are listed in Appendix B.

    Public comment period is closed.
