ascii armor is just a standard header and footer, wrapped around base64-encoded data plus a checksum: https://tools.ietf.org/html/rfc4880#section-6 If you have perl installed, you can use the attached script to convert from a binary version to an ascii-armored version. Invoke it like: openpgp-armor-convert < foo.sig > foo.asc hth, --dkg
