    abstract =  {This document describes a method of embedding alternative sets of cryptographic materials into X.509v3 digital certificates, X.509v2 Certificate Revocation Lists (CRLs), and PKCS \#10 Certificate Signing Requests (CSRs). The embedded alternative cryptographic materials allow a Public Key Infrastructure (PKI) to use multiple cryptographic algorithms in a single object, and allow it to transition to the new cryptographic algorithms while maintaining backwards compatibility with systems using the existing algorithms. Three X.509 extensions and three PKCS \#10 attributes are defined, and the signing and verification procedures for the alternative cryptographic material contained in the extensions and attributes are detailed.},
