When you deliver an investigation report, your client needs to trust that the evidence you present is exactly what you found — unaltered, complete, and authentic. Hashing makes that trust verifiable.
SHA-256 hashing creates a unique fingerprint for any file. Change a single pixel in an image or a single character in a document, and the hash changes completely. This means anyone can verify that evidence hasn't been tampered with.
We include hash values in every forensics deliverable, along with chain-of-custody documentation showing who handled each piece of evidence and when.
