    Hi All,

    NIST has released an initial public draft (ipd) revision of Special Publication (SP) 800-131A, Transitioning the Use of Cryptographic Algorithms and Key Lengths.
     
    NIST provides cryptographic key management guidance for defining and implementing appropriate key-management procedures, using algorithms that adequately protect sensitive information, and planning for possible changes in the use of cryptography because of algorithm breaks or the availability of more powerful computing techniques. This publication provides guidance on transitioning to the use of stronger cryptographic keys and more robust algorithms.
     
    This revision proposes a) the retirement of ECB as a confidentiality mode of operation and the use of DSA for digital signature generation and b) a schedule for the retirement of SHA-1 and the 224-bit hash functions. This draft also discusses the transition from a security strength of 112 bits to a 128-bit security strength and to quantum-resistant algorithms for digital signatures and key establishment.
     
    The public comment period is open through December 4, 2024. See the publication details for a copy of the draft and instructions for submitting comments.
