title: "Download Integrity"

categories: bits

Some FLOSS provide md5 hashes to verify the integrity of the what we are about to download (installers, source code, etc.). On macOS, using ZSH, we can validate the integrity of our file with:

$ [ "$(md5 -q /path/to/file)" = "c7537c3cf1d5d2fc2b744af8025c0cf3" ] && (echo "valid")

Where c7537c3cf1d5d2fc2b744af8025c0cf3 would be the md5 hash provided by the developers.
