Cryptographic Standards and Guidelines

Project Overview

Users of the former "Crypto Toolkit" can now find that content under this project. It includes cryptographic primitives, algorithms and schemes are described in some of NIST's Federal Information Processing Standards (FIPS), Special Publications (SPs) and NIST Internal/Interagency Reports (NISTIRs).

Guideline for Using Cryptography in the Federal Government

  • Directives, mandates and policies (SP 800-175A)
  • Cryptographic mechanisms (SP 800-175B)
    • 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.
