Password-Based Key Derivation Function 2 (PBKDF2), standardized in RFC 2898 / PKCS #5 v2.0, applies a pseudorandom function (like HMAC-SHA256) to an input password along with a cryptographic salt, repeating the process hundreds of thousands of times to produce a strong key.

What is the OWASP recommendation for PBKDF2 iterations?

As of 2024, OWASP Password Storage Cheat Sheet recommends at least 600,000 iterations for PBKDF2-HMAC-SHA256, or 210,000 iterations for PBKDF2-HMAC-SHA512 to protect against GPU brute-force attacks.

Why PBKDF2 Thwarts Password Cracking Clusters

Standard cryptographic hash functions (such as MD5 and SHA-256) are engineered to be extremely fast for data integrity verification, allowing attackers using specialized GPU arrays to compute billions of guesses per second.

PBKDF2 is intentionally designed to be computationally expensive (slow). By forcing a computer to calculate 100,000+ sequential rounds of HMAC, it elevates the cost of brute-forcing to make large-scale offline dictionary attacks economically unfeasible.
