Thanks Justin!

Would be great if you could in addition provide .asc signatures for the
files using security/gnupg.

1. Create key: gpg --gen-key

2. Export public key (put on website): gpg --export --armor youremailaddress > mykey.asc

3. Sign file: gpg --armor --detach-sign snapshot.tar.gz

4. Upload snapshot.tar.gz.asc

Then, everyone who trusts your public key can verify that these binaries
were actually signed by you using:

gpg --verify snapshot.tar.gz.asc snapshot.tar.gz

Given that your private key stays secured this adds another layer of
security. Right now, even using SHA256 checksums would be no more secure
in case you download the checksum file (md5.txt or sha256.txt) from the
same mirror server as the file itself.

If you need help setting this up, please let me know.
