From 977bcac2d56a8793ed93b4aac7016ef36b51a07f Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Fri, 12 Jun 2026 19:34:27 +0200 Subject: irmd: Add issuer and digest pinning to OAP A peer certificate that verifies against the CA store could have been issued by any trusted CA, and a peer could pick any supported digest for its signature. Tighten the authentication contract with two local policies. cacert= pins the issuing CA: a peer certificate, if presented, must chain through the pinned CA. Whether a certificate is mandatory at all remains controlled by auth= alone. digest= now also pins the signature digest: a classical peer must sign with the locally configured digest, and may not omit the digest NID to fall back to the key's default digest. PQC signatures (ML-DSA, SLH-DSA) have an intrinsic digest and may be NID_undef.
