Basics
This is a PGP-signed list of all resources on this website alongside with their integrity hashsums.
Line format: <sha256> <path>.
Update subkeys (optionally), download index file, extract it and check the signature.
curl https://yrz.am/gpg | gpg --import --import-options=merge-only
curl https://yrz.am/index.sig | gpg --decrypt -o "$LIST_FILE"
Verification
Every file on this website is inherently signed by my PGP key. To verify some resource, download it, compute sha256 and simply check if it is on the list.
temp=$(mktemp)
if curl -sSL "$URL" -o "$temp"; then
sha=$(sha256sum "$temp" | awk '{print $1}')
grep $sha "$LIST_FILE"
fi
Dumps
It is trivial to download the entire website or any part of it. Site is static and you have a file with all existing paths (and even hashes for incremental downloads). grep what you need, loop through lines, on each iteration create local directory and download item there.
Note: index.html is redirected to /, so the code needs either to perform static replacement or to follow redirect.
