BLAKE2 Algorithms and Identifiers for use in the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile

This document describes the conventions for using the BLAKE2b-512 hash function with each of the following algorithms: RSA Encryption Scheme - Optimal Asymmetric Encryption Padding (RSAES-OAEP), RSA Probabilistic Signature Scheme (RSASSA-PSS), RSA Public-Key Cryptography Standards #1 version 1.5 (RSASSA PKCS#1 v1.5), Digital Signature Algorithm (DSA), Elliptic Curve Digital Signature Algorithm (ECDSA), and Edwards-curve Digital Signature Algorithm (EdDSA). This specification applies to the Internet X.509 Public Key Infrastructure (PKI) when digital signatures are used to sign certificates and certificate revocation lists (CRLs). This document also specifies the object identifiers for the combinations of the BLAKE2b-512 hash function with the aforementioned algorithms.
