Checksum Utility

Checksum Utility calculates and compares single checksums (also known as hash values) on your Mac.

 

 

Why checksums are useful

• Is my backup working? Compare a file with it’s backup.
• Is my harddisk damaged? Compare a file with it’s checksum from a year ago.
• Is my RAM corrupt? Compare an important file with it’s duplicate.
• Is this downloaded file compromised? Compare a file with it’s checksum on a webpage.

Features

• Supported checksum algorithms:
  CRC 32, MD5, SHA 1 and MD2, MD4, SHA 2: SHA 224, SHA 256, SHA 384 and SHA 512.
• Save a calculated checksum as .checksum file.
• Compare a file on disk, a .checksum file and a manually entered checksum in any combination.
• Guesses what algorithm a given checksum might be created with.
• You can test the correctness of Checksum Utility with zero-length checksums on your own.
• Substantial in-app help to let you know, what to do.
• Supports drag and drop.
• Checksums can be copied and pasted.
• 100% hand crafted native Mac application.

Checksum Utility is made to calculate single checksums. If you need to calculate the checksums of a whole folder or want to compare two folders, then Checksum Folders is for you.

New in this version (1.1.0)

• New and very efficient computation model.
• Very low memory usage for most algorithms.
• Shows the progress during the calculation of large files.
• Calculation of large files can now be interrupted.
• Several bugfixes.
• The usage with Yosemite has been optimized.
