FAQ
Can this crack passwords?
No. It only parses structure with regex; it never recovers the original password.

RSA Key Pair Generator
RSA Public/Private Key Pair Generator (PEM)
Generate RSA key pairs in the browser with the Web Crypto API at 1024, 2048, or 4096 bits and export standard PEM text. Private keys are not sent over the network. Intended for development, testing, and learning—not as a production key-management system.

Password Strength Tester
Password Strength Tester — Entropy and Crack-Time Estimate
Estimate password entropy, character-pool size, and theoretical offline crack time from length and character classes, with improvement suggestions. Evaluation runs entirely in the browser; passwords are not uploaded. Results are theoretical heuristics, not a guarantee of real-world security.
