Verifying Signatures

The sha512 and asc files are signature files and can be used to verify the integrity of the downloaded distribution package.

Use the following commands to verify the integrity:

  • gpg --print-md sha512 fileName.tar.gz

  • gpg --verify fileName.tar.gz.asc

It might be necessary to import the KEYS file to verify the integrity of the asc files.

That can easily be done with:

  • gpg --import KEYS

More information about release signing and verifying signatures can be found here.
