Verify the Integrity of Downloads
It is essential that you verify the integrity of the downloaded files using the ASC signature or SHA checksum.
The ASC signatures can be verified using PGP or GPG. Begin by following these steps:
- Download the KEYS file.
- Download the
.ascsignature for the relevant distribution file. - Verify the signature.
- If using GPG:
$ gpg --import KEYS $ gpg --verify <file-name>.asc <file-name> - If using PGP:
$ pgp -ka KEYS $ pgp <file-name>.asc
- If using GPG:
Alternatively you can [also] verify the SHA-512 checksum of the file. For example, using the sha512sum command:
$ sha512sum -c <file-name>.sha512
