About PBKDF2 Key Derivation

PBKDF2 Key Derivation implements the Password-Based Key Derivation Function 2 (RFC 2898, PKCS#5 v2.0), transforming a password and a cryptographic salt into a derived key by iterating an HMAC pseudorandom function hundreds of thousands of times. This key-stretching process makes brute-force and dictionary attacks computationally expensive, since an attacker must repeat the entire iteration count for every password guess. PBKDF2 with HMAC-SHA-256 is a NIST-recommended algorithm used in WPA2 Wi-Fi authentication, iOS data protection, and many database password hashing implementations. This browser tool computes PBKDF2-derived keys using the Web Crypto API for trustworthy in-browser computation without sending your password anywhere.

How to Use

Enter your password in the password field and provide a cryptographic salt, or click the random salt button to generate a secure 16-byte random salt. Select the HMAC hash algorithm, choosing SHA-256 for general use or SHA-512 for a higher security margin. Set the iteration count following NIST guidance of at least 600,000 iterations for HMAC-SHA-256, and specify the output key length in bytes such as 16 for AES-128 or 32 for AES-256. Click Derive to compute and display the result in hexadecimal or Base64, then copy the output for cross-implementation testing or compliance documentation.

Common Use Cases

Deriving AES-256 encryption keys from user-supplied passwords for encrypting files or sensitive application data stored at rest
Testing and tuning PBKDF2 iteration counts and salt lengths during the security design phase of new authentication systems
Verifying that a given password and salt reproduce the expected derived key stored in a legacy database or configuration archive
Comparing derived key outputs across HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512 to select the right algorithm for compliance requirements
Demonstrating key stretching and salting concepts interactively in applied cryptography courses and developer security workshops
