Everything built around one job: verifiable integrity
FileToHash covers the full loop of a hashing task — generate a value, watch for change, and leave a record someone else can check.
Fast, accurate, and repeatable
Fast file & folder hashing
Select a single file, a batch of files, or a full folder tree. FileToHash walks the directory structure and hashes each item in sequence, so nothing gets skipped.
MD5, SHA-1 & SHA-256 support
Choose the algorithm your case or policy requires, or generate more than one value for the same file in a single pass.
Batch hashing workflow
Queue a whole evidence set and work through it in one session, with results kept in the order you added them.
Results you can hand to someone else
Professional PDF reports
Export a clean, structured PDF for each hashing session — file names, paths, algorithms, digest values, and timestamps laid out for a case file or internal review.
CSV export
Send the same results to CSV when you need to sort, filter, or pull hashing data into a spreadsheet or another case-management tool.
Know when something changed
These features are designed to support forensic workflows and help detect tampering — they describe FileToHash's own safeguards, not a guarantee about legal outcomes.
Integrity status warning
If a file is modified while it is being hashed, FileToHash flags the session so you know the result may not reflect the file's original state — and can re-run it.
Tamper-evident audit logs (HMAC-SHA256)
Session logs are signed with HMAC-SHA256. If a log entry is altered after the fact, the signature will no longer match — helping you notice, not preventing every possible attack.
Security event logging
Application-level events — such as sign-ins to settings, report exports, and configuration changes — are recorded with a timestamp for later review.
Local-only processing
Hashing happens entirely on your Windows machine. Files and folders you select are never uploaded anywhere by FileToHash.
Built for mixed technical teams
Dark & light theme support
Switch between a dark theme for lab and field conditions and a light theme for bright offices or shared screens.
Simple interface
Clear labels, a straightforward hashing flow, and plain-language results — designed so both forensic specialists and non-technical reviewers can use it confidently.
