snapaid

This is a utility that will make it easier to find and download the correct snapshot. It will also fetch and verify the GPG signature and hash of the snapshot to ensure that you are getting the correct file.

Screen shot of snapaid.sh find

Quick Start

The only file needed for this is the snapaid.sh script. The other files are used for generating the index.

$wget https://raw.githubusercontent.com/jmgurney/snapaid/master/snapaid.sh
$chmod 755 snapaid.sh
$./snapaid.sh find

Notes

This repository will be signed by my FreeBSD GPG key. It is available at: [https://www.freebsd.org/doc/en_US.ISO8859-1/articles/pgpkeys/pgpkeys-developers.html]

You will NOT see the verified tag on github, because if I upload my key to github, github will mark edits done on the website as verified even though it was not authenticated by my GPG key. This destroys the point of signing commits, as anyone who is able to take over my github account and not my GPG key, could now impersonate me, and make malicious changes.

NOTE: The xz vs non-xz versions of some of the images are not able to be differentiated. Currently shorting rules should always put the xz version before the non-xz version.

NOTE: Only snapshots that have SHA512 hashes are included. This excludes most snapshots from 2015 and before. The tool could be updated to include SHA256, but not a priority currently.

NOTE: Not all of the snapshots are in the database. Some snapshot names, like 11.0-RC1, don’t contain all the info others do, and are not included. In the future, hopefully this will be fixed.

backend

The backend is just a simple text file the indexes all the published snapshots. It is built from the emails to the freebsd-snapshot list. After verification of the email’s signature, the SHA512 entry lines are extracted, the file name is parsed, and added to the complete index. The message-id of the email is in the index so that the frontend can d/l the original email, verify the GPG signature locally. The complete index is used for verifying a snapshot that has already been downloaded. Another index is also maintained which only contains the currently available to d/l snapshots.
