Project needs immediate Windows trust for a public open source release so code signing certificate choice and hardware tokens matter. Certificate arrives on a USB token in a plain envelope, vendor names (SafeNet/Gemalto/Thales) and CA docs mismatch, and signing requires Windows signtool or workarounds. Practical fixes: use OpenSC and PKCS#11 to talk to tokens, fix timestamp server calls, prefer YubiKey attestation or cloud HSMs for distributed signing, and favor regular code‑sign certs after the June FIPS mandate.
