Argon2 Digest Calculator

Calculate or verify a digest with Argon2. Enter the data, choose the digest options, then copy the calculated value.

Tool workspace

Your input stays in this browser.

Add the required input to continue.

Needs input

Run the tool when your input is ready.

Defaults use Argon2id with 19456 KiB, 2 iterations, and parallelism 1. Each blank salt creates a new random salt.

Options

Leave blank for a new random salt on each run. Explicit salts must decode to 8–1024 ASCII bytes.

Argon2 Digest Calculator uses Argon2 password derivation for the supplied input. The operation returns an encoded password hash or derived key string. The digest or checksum format is specific to Argon2 Digest Calculator.

The operation returns an encoded password hash or derived key string. The digest or checksum format is specific to Argon2 Digest Calculator. This result runs in the browser for this catalog category. Processing runs in the browser.

Password hashing or derivation protects stored verification data; it does not provide authentication controls by itself.

Instructions

  1. Provide text or data for this tool.
  2. Use a non-production password and salt for the fixture. This applies to Argon2 Digest Calculator.
  3. Record cost settings with the output because they affect verification. This applies to Argon2 Digest Calculator.
  4. Use a dedicated password-hashing policy before production deployment. This applies to Argon2 Digest Calculator.

Example

Input: Password "correct horse" with the operation defaults and a public salt such as "somesalt". Algorithm operation: Argon2 Digest Calculator.

Settings: Argon2 Digest Calculator: Use the documented salt, cost, memory, parallelism, rounds, or output-length controls. Keep the password and salt in text input fields. Use the operation's encoded text output.

Result: The operation returns an encoded password hash or derived key string. The digest or checksum format is specific to Argon2 Digest Calculator.

Limits

  • Argon2 Digest Calculator: A hash output is not reversible encryption.
  • Argon2 Digest Calculator: Security depends on cost settings, secret handling, and independent password policy.
  • Argon2 Digest Calculator: This local result does not configure account lockout or rate limiting.
