Details and limitations

Everything runs in your browser; text, files and keys are not uploaded.

Input is limited to 100,000 characters per field. Cancel stops the worker and discards the pending result.

Hashing is one-way. Encoding and obfuscation do not keep data secret.

FAQ

Are my keys or files uploaded?

No. Calculation happens locally in a Web Worker. Clearing or leaving the page discards its working state.
