PBKDF2 Key Derivation

PBKDF2 demo; choose high iterations. Consider Argon2/scrypt for stronger resistance.
PBKDF2 derives keys from passwords. Use large iteration counts and unique, random salts. Consider Argon2 or scrypt for stronger resistance.

About PBKDF2

PBKDF2 is a standard password-based key derivation function. Output depends on passphrase, salt, iterations, and hasher. Use high iteration counts and random salts; evaluate Argon2 or scrypt for new systems.

FAQs

What parameters matter most?
Iterations (cost), salt, selected hash, and output length directly affect security.
When to choose Argon2 or scrypt?
For better GPU/ASIC resistance and memory hardness; PBKDF2 is still widely supported.
Does this tool upload my data?
No. Key derivation is computed locally in your browser.
