MD5 Master

Drop a file. Calculate its MD5. Check it against the original.

Check a download, compare a backup or share a checksum with a file. Drop a file onto MD5 Master, or open it with ⌘O, to calculate its MD5. Copy the result, save it as text or compare it with a checksum on your clipboard. Everything runs on your Mac.

How do I check a downloaded file?

Drop the downloaded file onto MD5 Master. Copy the publisher's MD5 checksum on its own, then click Verify with Clipboard. Leading and trailing spaces are ignored, as is letter case.

Can it calculate checksums for folders or several files?

MD5 Master works with one file at a time. It does not calculate a combined checksum for a folder.

Does it support SHA-256 or other algorithms?

No. MD5 Master calculates MD5 checksums. The reference checksum you compare it with must also be MD5.

Is MD5 suitable for security checks?

Use MD5 to spot accidental corruption or incomplete downloads. MD5 is not secure against deliberate tampering, and a matching checksum does not prove that a file is safe or authentic.
