hashSum (Free GPL license)

A program to compare files and to calculate hash sums. MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512, SHA3_224, SHA3_256, SHA3_384, SHA3_512, KECCAK_224, KECCAK_256, KECCAK_384 and KECCAK_512 are supported.

What is a hash function?

More Screenshots (And a good manual, too.)

Possibilities

• Choose whether you want to calculate the hash sums, or compare two files
• You can choose the calculation algorithm. (MD4, MD5, SHA1, SHA224, SHA256, SHA384, SHA512, SHA3_224, SHA3_256, SHA3_384, SHA3_512, KECCAK_224, KECCAK_256, KECCAK_384 and KECCAK_512)
• You can create lists of checksums that are stored as a text file.
• You can recursively create lists of hash sum files.
• You can compare against a selected hash sum.
• You can check which files have changed, who's
  new and what has been lost since the last time you checked.
• You can choose the operating system's "Open" and "Save" dialogues, or the program's own
• lists of checksums can be auto saved. li>
• You can calculate and compare hashsummor for text strings. li>
• You can choose a default filename to save the checksum lists. li>
• Swedish, Greek and English menus
• The program can check for updates.
• The program supports "Drag and Drop".

The program can handle four languages
