# A PowerShell script that checks the checksum of one or more linux ISO files for four common Linux distros.
# Supports: POP!_OS, Mint, Manjaro and Ubuntu

# - It's faster and more accurate than manually checking.
# - Be sure to download the ISO files solely from the official sites!
# - To be clear this DOES NOT also check GPG signatures.
