About this tool
Verifying a download's checksum is the simplest defense against corrupted or tampered files. Drop a file here and it is hashed in your browser with streaming reads — nothing is uploaded, and files of any size work.
Paste the published checksum into the compare field and the tool highlights a match or mismatch instantly, whatever the algorithm.
Like everything on encrypt.tools, this runs entirely in your browser — nothing you enter is transmitted or stored.
Do the same in a terminal
Reproduce or cross-check this tool with standard command-line utilities. For deterministic operations like hashing and encoding, the output matches exactly.

Is my file uploaded?+
No — the file is read and hashed entirely in your browser. Nothing is sent to a server, so files of any size and sensitivity are safe to check.
How do I verify a download?+
Drop the file here, then paste the checksum the publisher listed into the compare field. A match confirms the file is intact and untampered.
Which algorithm should I compare?+
Use whatever the publisher provided — usually SHA-256. The tool computes SHA-256, SHA-1, SHA-512, and MD5 so you can match any of them.
