Generate a checksum (MD5 or SHA-256) of any file — useful for verifying a download wasn't corrupted or tampered with.
Frequently asked questions
Comparing a file's hash against a publisher-provided checksum confirms the file downloaded completely and wasn't corrupted or tampered with in transit.
Use whichever the publisher provided a checksum for — SHA-256 is the more modern, collision-resistant standard, but MD5 is still commonly published for basic integrity checks.
