since 1.0.4, gnupg comes with a tool named gpgv which does exactly what you want. It is smaller than gpg but still quite large. If you need a really slim verification tool, have a look at SFSV ( This is a tool to OpenPGP sign an ELF file and embed the signature in the ELF file. The library part then can be used by the ELF loader to check that signature. It is not very fast but the memory footprint is about 18k. useful for embedded systems to check. It is GPLed; if you have problems with this, please contact me privately. Werner -- Archive is at - Unsubscribe by sending mail with a subject of "unsubscribe" to
