Digital signature standard

“

The Digital Signature Standard is a U.S. federal government standard for appropriate digital signature algorithms. The standard is published by the National Institute for Standards and Technology, NIST, and the current version of the standard came out in 2023. It's published as Federal Information Processing Standard or FIPS 186-5. Here's a quick look at the table of contents for this 86-page document. As you can see, it contains great detail on the acceptable implementations of digital signatures in the federal government. What you need to know about the digital signature standard is that it supports three different digital signature algorithms for use in the U.S. government. The first is the Rivest-Shamir-Adleman or RSA algorithm. The Digital Signature Standard endorses the use of RSA for digital signatures that are described in American National Standard X 9.31 and Public Key Cryptography Standard or PKCS Number 1. The second endorsed algorithm is the Elliptic Curve Digital…
