What Is Argon2i?

Argon2i is the data-independent variant of Argon2 where memory access patterns are predetermined, providing resistance to side-channel attacks at the cost of some GPU resistance, making it suitable for password hashing in shared environments.

Use Cases

  • Password hashing in shared environments
  • Side-channel attack resistance required
  • Cloud password storage
  • Virtualized environments
  • Where timing attack resistance is critical
!

Security Notice

Argon2i has lower GPU resistance than Argon2d. Argon2id provides the best balance for most password hashing scenarios.

How to Generate a Argon2i derived value

  1. Choose UTF-8, Hex, Base64 input mode.
  2. Enter the text or encoded bytes you want to process.
  3. Adjust the Argon2i options if your use case requires non-default settings.
  4. Click Generate Argon2i 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 Argon2i

  • Do not choose it when maximum GPU resistance is the main requirement; prefer Argon2id or Argon2d.
