[PATCH 1/6] x509: Add OIDs for FIPS 202 SHA-3 hash and signatures

From: Dimitri John Ledkov
Date: Sun Oct 22 2023 - 14:22:38 EST


Add OID for FIPS 202 SHA-3 family of hash functions, RSA & ECDSA
signatures using those. Limit to 256 or larger sizes, for
interoperability reasons. 224 is too weak for any practical uses.
