A system and method for verifying a cryptographic access code is provided. If a set of cryptographic access components are quantum-aware, the system can obtain a post-quantum encryption and/or decryption algorithm from a context-specific non-critical extension in a private OID namespace, such as SABER, Kyber, Enhanced McEliece, or RLCE. If the set of cryptographic access components are quantum-aware, the system can obtain a post-quantum signature or verification algorithm from the private OID namespace. The system can validate a root of trust specified in a TAL record; confirm that a respective certificate, CRL, or TAL is specified in at least one Manifest record; confirm that a hash of the respective certificate, CRL, or TAL matches a recorded hash in a respective Manifest listing the respective certificate, CRL, or TAL; and confirm that a respective CRL or Manifest is fresh.
