Trusted Hashing for Digital Evidence Integrity
FileToHash helps investigators, cybersecurity teams, and forensic professionals generate, verify, and document cryptographic hash values for files and folders.
Built for evidence, not just files
FileToHash is a Windows desktop hashing utility designed for digital evidence integrity verification. It allows users to select files or folders, generate cryptographic hash values, and export results into professional reports. The tool is built for forensic workflows where documentation, repeatability, and integrity verification matter.
Every hashing session can be exported as a structured record — so the value you generate today can be reproduced, reviewed, and cross-checked later, by anyone on your team.
Explore all features →FileToHash supports forensic workflows — it does not guarantee legal admissibility on its own. Outcomes depend on your process, chain of custody, and jurisdiction.
Its audit logging is tamper-evident, built to help detect changes — not an unbreakable, tamper-proof guarantee. No local desktop tool can honestly claim that.
Hashing runs entirely on your machine. FileToHash does not upload your files anywhere.
Everything a hashing workflow needs
From a single file to a full evidence folder, FileToHash keeps the process fast, repeatable, and documented.
Fast file & folder hashing
Hash single files or entire directory trees, with results returned quickly even on large evidence sets.
MD5, SHA-1 & SHA-256
Generate values using the algorithms most requested in forensic and compliance workflows.
Batch hashing workflow
Queue multiple files or folders in one session and work through evidence sets in a consistent order.
Professional PDF reports
Export hashing results as clean, structured PDF reports suitable for case files and documentation.
CSV export
Send hashing results to CSV for further review, spreadsheets, or integration with other case tools.
Integrity status warning
Get alerted when a file changes while it's being hashed, so you know exactly when to re-verify.
Tamper-evident audit logs
Session logs are signed using HMAC-SHA256, helping surface unexpected edits to the record.
Security event logging
Key application and hashing events are recorded, giving you a clear timeline of what happened, when.
Dark & light theme
Work comfortably in the lab, the field, or the office with a theme that suits your environment.
