Verify Releases

It is essential that you verify the integrity of the downloaded files using the PGP, and/or SHA signatures. published with every Flagon release. Please read Verifying Apache HTTP Server Releases for more information on why you should verify our releases. We strongly recommend you verify your downloads with at least PGP. Guidance for doing so is provided below.

PGP Signatures

The PGP signatures can be verified using PGP or GPG. First download the KEYS as well as the asc signature file for the relevant distribution. N.B. Make sure you get these files from the main distribution directory, rather than from a mirror. Then verify the signatures using the following example

$ gpg --import KEYS

$ gpg --verify apache-flagon-{product}-{version}

SHA512 Signatures

Alternatively, you can verify the SHA512 signatures on the files. A unix program called md5 or md5sum is included in many unix distributions. Use the following example

$ sha512sum apache-flagon-{product}-{version}

... output should match the string in apache-flagon-{product}-{version}
