Post-Quantum-Cryptography as property

Background

As a result of restructuring the list (cryptoClass and CryptoSubClass values), effort tracked in #68 the Cryptography Group took the decision on 2026-04-22 to consider Post-Quantum-Cryptography (PQC) a new property, instead of a cryptoSubClass

Rationale

PQC follows a logic that does not fit in the cryptoClass structure. It would require us to challenge the current values of cardinality we follow in cryptoClass and cryptoSubClass, among other considerations. Pre and Post Quantum Cryptography tits better as a different dimension in the algorithms categorizations

Description

Discuss and reach a consensus on the description of this new property, related with PQC. Evaluate which algorithms are currently affected and use the existing candidates to the list #43 to check if the proposed property make sense.

Actions

• Define a proposal for the new property. Include
  • The changes in the list properties description
  • Algorithms affected and the new description for each one of them
  • how would potential candidates be described based on this proposal
• Reach consensus about this proposal wirthin the Cryptography Group
• Create and submit a PR
• Review and merge the PR

DoD

• Link to the proposal: https://github.com/spdx/cryptographic-algorithm-list/issues/73#issuecomment-5267793501
• Consensus reached within the Cryptography Group?
  • Link: https://hackmd.io/@toscalix/Bym7YorOze
• Link to PR
• Link to the new version of the list property description file including the new property description
• Link to the description of the affected algorithms

Review the proposal in the linked issue comment, the Cryptography Group consensus in HackMD, and the existing candidates from #43, while checking the restructuring context in #68. The work is already represented by open PR #91; completion requires the PR and the new property description and affected-algorithm descriptions to be linked in the issue DoD.
