ToolbitHash Generator for MD5 and SHA
Produce a checksum for a string or a file and compare it against the one you were given. Hashing happens with the Web Crypto API in your tab, so the file never leaves your disk.
What the Hash Generator does
- MD5, SHA-1, SHA-256, and SHA-512 in one pass.
- Hash text input or drop a file to checksum it.
- Compare against an expected value with a match indicator.
- Uppercase and lowercase hex output.
How to use it
- Paste text or drop a file onto the input panel.
- Read the digest for each algorithm.
- Paste the expected checksum to confirm a match.
Why it runs locally
Toolbit has no backend. The Hash Generator is implemented with standard browser APIs, so your input is processed in the tab and never uploaded, logged, or retained. That is what makes it safe to paste real data into — and it is also why the tool keeps working with the network disconnected, once you have installed Toolbit as an app.
Frequently asked questions
- Is MD5 still safe to use?
- Not for security. MD5 and SHA-1 are broken for collision resistance and should only be used for non-adversarial integrity checks. Use SHA-256 or better for anything that matters.
- Are my files uploaded to hash them?
- No. Files are read locally and hashed with the browser's Web Crypto API. Nothing is transmitted.
- Can I hash a large file?
- Yes. Files are streamed in chunks, so multi-hundred-megabyte files hash without exhausting memory.
