Hi, The key is available (gpg --list-keys --fingerprint 2D51AAC6), but I don't think that will solve the issue. It seems that I might have generated the signature incorrectly.
I checked and, yes, there are binaries that were signed correctly. Verification worked for jspwiki-portable-2.12.2-woas.zip with jspwiki-portable-2.12.2-woas.zip.asc. Best regards,
