 Gitea signs all binaries with a [GPG key](https://pgp.mit.edu/pks/lookup?op=vindex&fingerprint=on&search=0x2D9AE806EC1592E2) to prevent against unwanted modification of binaries. To validate the binary download the signature file which ends in `.asc` for the binary you downloaded and use the gpg command line tool.
