##Verifying a release It is essential that you verify the integrity of the downloaded files using the PGP signatures or SHA512 checksums. Please read How to verify downloaded files for more information on why you should verify our releases.
The PGP signatures can be verified using PGP or GPG. First download the KEYS file as well as the .asc signature files for the relevant release packages. Make sure you get these files from the main distribution directory, rather than from a mirror. Then verify the signatures using:
% gpg --import KEYS % gpg --verify downloaded_file.asc downloaded_file
% pgpk -a KEYS % pgpv downloaded_file.asc
% pgp -ka KEYS % pgp downloaded_file.asc
Alternatively, you can verify the hash on the file.
Hashes can be calculated using GPG:
% gpg --print-md SHA256 downloaded_file
The output should be compared with the contents of the SHA256 file. Similarly for other hashes (SHA512, SHA1, MD5 etc) which may be provided.
Windows 7 and later systems should all now have certUtil:
% certUtil -hashfile pathToFileToCheck
HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512
Unix-like systems (and macOS) will have a utility called md5, md5sum or shasum.
