PBKDF2 key derivation
ClientRun PBKDF2 with your password, salt, iterations, and desired key length—uses Web Crypto locally.
How to use
Enter password, salt, iterations, hash, and key length; click Derive.
About PBKDF2 key derivation
Derive keys with PBKDF2 (SHA-256/512) in the browser—hex and Base64 output for crypto workflows. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.
How to use this page
Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.
Limits and safety
Utilities here are for development and inspection—do not paste live production keys, PANs, or recovery codes into any browser tab you do not control.

Common use cases
- Verify KDF parameters match another implementation.
- Generate derived keys for test fixtures.
Common mistakes to avoid
Low iteration counts
Production passwords should use high iterations (e.g. 100k+ for SHA-256)—this tool does not enforce a minimum.
FAQ
Is my password sent to a server?
No—derivation runs entirely in your browser via Web Crypto.
