How to use Argon2id & scrypt Password KDF

Derive interoperable password hashes with bounded Argon2id or scrypt parameters in a dedicated local worker.

What to provide

Enter the password or passphrase to derive. It is treated as sensitive and never included in presets.

Use at least eight bytes and a fresh unpredictable salt for each stored password.

  1. Paste, type, or drag and drop a supported text file into the input area.
  2. Place the second value or file in the adjacent panel. Sensitive fields are masked by default.
  3. Choose the options that match your intended result.
  4. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

Use “Swap inputs” to reverse the comparison without copying either value.

What the result means

An encoded Argon2id PHC string or a labeled scrypt derivation with the selected parameters.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

  • All input and output remains in this browser tab and is never uploaded or saved. Browser benchmarks differ from production servers; calibrate memory and time cost on the system that verifies passwords.
