To guarantee that a downloaded GnuPG version has not been tampered with by malicious entities we provide signature files for all tarballs. Instructions on how to verify a signature can be found at integrity checking page.

The used signature keys are reported below. The keys are also signed by the long term keys of the respective owners. A document with the same information and a qualified digital signature of the project's founder is also available: https://gnupg.org/signature-key.pdf

Current releases are signed by one or more of these keys:
