Questions
Which hash should I use?
Use SHA-256 or stronger. MD5 and SHA-1 are broken for security purposes, but are still fine for spotting accidental file corruption.
How do I verify a downloaded file?
Choose the file, then paste the checksum from the download page into Compare. A green match means the file is exactly the same.
Can a hash be reversed?
No — hashes are one-way. But short or common passwords can be guessed, which is why passwords must be stored with slow salted algorithms like bcrypt or Argon2, not plain SHA-256.
