PBKDF2 Hash Generator & Verifier
Generate PBKDF2 hashes from passwords with configurable salt, iterations, and algorithms. Verify passwords against existing PBKDF2 hashes. PBKDF2 is the industry standard for secure password storage and key derivation, providing protection against brute force and rainbow table attacks.
Salt should be random and unique for each password. Minimum 16 hex characters recommended.
Higher = more secure but slower
✅ Password Security Standard
- • Industry standard: PBKDF2 is recommended by NIST and used by major platforms
- • Brute force protection: Configurable iterations make attacks computationally expensive
- • Salt protection: Unique salts prevent rainbow table and dictionary attacks
- • Time-tested: Proven security record in production systems worldwide
- • Perfect for: Password storage, key derivation, and authentication systems
About PBKDF2
- • Algorithm: Password-Based Key Derivation Function 2 (RFC 2898)
- • Purpose: Derives cryptographic keys from passwords using iteration and salt
- • Security: Computational cost increases exponentially with iteration count
- • Salt requirement: Random salt prevents identical passwords from having same hash
- • Iteration count: Higher values increase security but reduce performance
- • Key length: Output size can be configured based on security requirements
- • Hash algorithms: Supports SHA-1, SHA-256, SHA-384, and SHA-512
- • This tool uses the browser's native Web Crypto API for optimal security
PBKDF2 Security Best Practices
Iteration Count: Use at least 100,000 iterations (OWASP recommendation 2023)
Salt Generation: Always use cryptographically random salt, minimum 16 bytes
Salt Storage: Store salt alongside hash, but separate from passwords
Hash Algorithm: Prefer SHA-256 or SHA-512 over SHA-1 for new implementations
Key Length: Use 32 bytes (256 bits) minimum for strong security
Migration: Consider migrating to Argon2 or scrypt for new applications
⚠️ Security Considerations
Client-Side Processing: This tool runs in your browser - passwords never leave your device
Salt Uniqueness: Never reuse salts - each password must have a unique random salt
Iteration Tuning: Balance security vs performance based on your system capabilities
Storage Security: Store hashes and salts securely in your database
Pepper Addition: Consider adding a server-side pepper for additional security
Modern Alternatives: For new projects, consider Argon2 or scrypt over PBKDF2
Common Use Cases
User Authentication: Secure password storage for web applications and services
Key Derivation: Generate encryption keys from user passwords
Database Security: Protect stored passwords in user databases
API Authentication: Create secure tokens from passwords or secrets
File Encryption: Derive file encryption keys from user passwords
Legacy Migration: Upgrade from weaker hash functions to PBKDF2
