What Is Argon2d?

Argon2d is the data-dependent variant of Argon2 where memory access depends on the password, providing maximum resistance to GPU attacks but vulnerable to side-channel attacks, making it ideal for cryptocurrency proof-of-work.

How to Generate a Argon2d derived value

  1. Choose UTF-8, Hex, Base64 input mode.
  2. Enter the text or encoded bytes you want to process.
  3. Adjust the Argon2d options if your use case requires non-default settings.
  4. Click Generate Argon2d Derived Value and copy the result.

Example Input

Sample input:

abc

Use this sample input, then copy the generated derived value from the result panel.

When Not to Use Argon2d

  • Do not use it where data-dependent memory access could expose side-channel risk.
  • Do not use heavy browser-side settings when JavaScript responsiveness matters.
