Derive Cryptographic Keys & Hashes with PBKDF2

Compute memory-hard key derivations using PBKDF2 with up to 600,000 iterations, custom salts, and SHA-512.

About This Tool

PBKDF2 (Password-Based Key Derivation Function 2) applies a pseudorandom function to input passwords along with a cryptographic salt, repeating the process hundreds of thousands of times to thwart brute-force attacks.

Key Features

Configurable iterations (10k to 600k)
Supports SHA-512 and SHA-256
256-bit and 512-bit key lengths
Hexadecimal and Base64 export

How to Use

  1. 1Enter the password to derive.
  2. 2Set your custom salt or click 'Random Salt'.
  3. 3Choose iteration count (100,000+ recommended) and key length (256 or 512 bits).
  4. 4Click 'Derive Cryptographic Key' to view the output in Hex or Base64.

Why Use ToolSnippet PBKDF2 / Password Key Hasher?

Complies with OWASP Password Storage Guidelines (100,000+ iterations for SHA-512).
Used in password managers (Bitwarden, 1Password) and encrypted storage systems.

Tips for Best Results

  • OWASP recommends at least 100,000 iterations of PBKDF2-SHA512 for modern applications

Frequently Asked Questions

What is PBKDF2 used for?

PBKDF2 is used to turn weak human passwords into strong, cryptographically secure keys for AES encryption and password storage.
