This directory contains release candidates for testing. The versions found here are unsupported, although feedback is greatly appreciated.
In various directories there is a file SHA256SUM which contains the sha256 checksum of the files in that directory. This SHA256SUM file is signed using the key of which the public part is available in the file MonetDB-GPG-KEY. This key is also available from keyservers:
gpg --recv-key 0x0583366F
You can then download the SHA256SUM file and check that it hasn't been tampered with:
gpg --verify SHA256SUM
Among other output, you should see the message
gpg: Good signature from "MonetDB Database System Packager <monet@cwi.nl>"
You should also see the message that the signature was made using the DSA key ID 0583366F (same number as mentioned above).
After this, you can verify that the downloaded files are correct:
sha256sum --check SHA256SUM
For all files you downloaded, you should see the name of the file followed by the work "OK".
In addition, all RPM files and DEB packages are also signed with this key. See the Fedora, epel (for Enterprise Linux), and deb (for Debian and Ubuntu) directories for more details.
