Verifying the Download

Before executing anything downloaded from, it’s important to verify the cryptographic signature and integrity of the file.


Note that is not a website that we control, and you should not trust it.

Before we can verify the authenticity of the BusKill app, it’s necessary to download gpg and the BusKill release key. For information on how to obtain these dependencies, see PGP Keys.

Once the BusKill Releases Signing Key is in your gpg keyring, execute the following to verify the BusKill app downloaded from

user@host:~/Downloads$ ls
buskill-linux-x86_64.v0.1.0.tar.bz2  SHA256SUMS  SHA256SUMS.asc

user@host:~/Downloads$ gpg --verify SHA256SUMS.asc
gpg: assuming signed data in 'SHA256SUMS'
