Use checksums to compare file content rather than relying only on filenames

A checksum is a digest calculated from file data. Two files with matching filenames can still contain different bytes, while a checksum comparison can help detect whether content changed.

The usefulness of a digest depends on the algorithm and the purpose. Integrity checking and security-sensitive cryptographic verification are not always the same requirement.

Practical checksum uses

  • Compare downloaded and expected file digests.
  • Check whether a file changed between two points in a workflow.
  • Create reference hashes for controlled archives or test files.

What to verify

  • Compare using the same checksum algorithm.
  • A checksum does not identify who created a file.
  • Use a modern algorithm where collision resistance matters.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
