How to verify...

How do I know the file I downloaded is from you?

GPG:

gpg --keyserver pgp.mit.edu --recv-key 0x61FB04EF

gpg --verify Asteroids.exe.sig

Powershell:

get-filehash Asteroids.exe -a sha512 | % { $_.hash }

get-filehash Asteroids.exe -a md5 | % { $_.hash }

Bash:

sha512sum Asteroids.exe
md5sum Asteroids.exe
