💡 Security Tips

Use SHA-256 with 310,000+ iterations for new applications
Use SHA-512 with 210,000+ iterations for high security
Always use a random salt of at least 16 bytes
Test performance on your production hardware
Store the complete formatted hash including all parameters
Avoid MD5 and SHA-1 for new applications

ℹ️ About PBKDF2 Generator

PBKDF2 (Password-Based Key Derivation Function 2) derives a cryptographic key from a password, salt, iteration count, and pseudorandom function. It is specified in RFC 8018 as part of PKCS #5 and is still widely supported in platform APIs, password-hash migration tooling, encrypted file formats, and authentication systems that need standards-based compatibility.

Why PBKDF2?

Industry standard: referenced by NIST password guidance in SP 800-63B and available in many runtimes.
Configurable iterations: increases attacker cost by repeating HMAC many times.
Salt support: unique salts prevent precomputed rainbow-table reuse across accounts.
Verification mode: compare a candidate password against stored parameters during migration or testing.
Compatibility: useful when a system cannot move to memory-hard schemes yet.

Algorithm Support:

SHA-256: good default for modern PBKDF2 deployments.
SHA-512: common on 64-bit systems and sensitive-data workflows.
SHA-384: supported for compatibility with specific policies.
SHA-1: legacy compatibility only; avoid for new designs unless required by an existing format.
MD5: not recommended for password storage; included only when analyzing old data.

Parameter Guidelines:

Iterations: tune on your production hardware so verification is slow enough to resist guessing but fast enough for sign-in traffic.
Hash length: 32 bytes (256 bits) is a practical default for many applications.
Salt: use a random 16-byte or longer salt for each password.
Modern alternatives: prefer memory-hard algorithms such as Argon2 from RFC 9106 when compatibility allows.
Privacy: use sample passwords in this web tool; do not paste production secrets.
