Interoperability test
CH-J Keys2 (keys2.ch-j.de) — Interoperability test, 8 November 2026: 30/30 certificates from CH-J Tools, GnuPG, rPGP and Sequoia PGP uploaded through VKS and retrieved by fingerprint in full, including subkeys.
Migration from keys.ch-j.de
The transition includes a planned migration of public keys from keys.ch-j.de to keys2.ch-j.de so they remain available to users. Missing signatures and subkeys in incomplete PQ certificates will need to be restored from a complete public certificate.
Status and limitations
Development version · The PQC backend is experimental. The certificate preservation test is neither a security certification nor verification of every server feature.
