PBKDF2 Password Hash

Generate PBKDF2-derived keys locally using the Web Crypto API.

PBKDF2 (SHA-256) of (empty)
Click Generate...
Use a random salt (16+ bytes recommended).
Typical: 100,000 or more.
Your input never leaves your device; hashing is done locally using Web Crypto.

How to Use

01

Enter Base Secret

Input the password or passphrase you want to strengthen. This serves as the initial key material.

02

Provide a Salt

Enter a random string (salt) of at least 16 bytes. This prevents attackers from using precomputed tables.

03

Set Iterations

Choose the number of iterations. A higher count makes the derivation slower and more secure against brute-force.

Frequently Asked Questions

What is PBKDF2?

PBKDF2 (Password-Based Key Derivation Function 2) is a standard method for deriving cryptographic keys from a password. It applies a hash function many times to make the process slow enough to thwart attackers.

Why use the Web Crypto API?

Using the Web Crypto API allows for hardware-accelerated, secure cryptographic operations directly in your browser. It's faster and more secure than traditional JavaScript implementations.

What is a recommended iteration count?

The OWASP recommendation for PBKDF2 with SHA-256 is at least 600,000 iterations. Our tool defaults to 100,000, but you can increase it for enhanced security.
