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.

Compatibility algorithms such as DES, RC4, MD2, MD4, SHA-1 and Type 7 are retained for existing systems; choose a modern algorithm for new designs.

FAQ

Are my keys or files uploaded?
