What does PBKDF2 do?
PBKDF2 repeatedly applies a pseudorandom function to a password and salt to derive key material.

About this Tool
Use this PBKDF2 generator for compatibility testing, key derivation experiments and migration work. Configure the salt, iteration count, digest and output length while keeping all inputs local.
Examples
- PBKDF2 with SHA-256
- Derive a 256-bit key
- Test 600000 PBKDF2 iterations
Frequently Asked Questions
Why are iterations important?
A higher iteration count makes each password guess more expensive for attackers.
Should the salt be secret?
No. The salt may be stored with the derived value, but it should be random and unique for each password.
