Benchmark live Web Crypto Subtle password derivation performance and evaluate GPU brute-force resistance.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Enter a sample password, salt, and desired iteration count.
Click 'Run Live In-Browser Benchmark' to measure hardware execution latency.
Review throughput (hashes/sec), OWASP compliance status, and GPU cracking resistance.
Yes! It uses the browser's native window.crypto.subtle engine to perform true PBKDF2 key derivations.
Argon2id uses memory hardness (e.g. 64MB RAM), making high-speed parallel GPU/ASIC cracking economically infeasible.
Zero-egress companion tools in the Security & Network suite
Measure cryptographic randomness, Shannon entropy (0-8 bits/byte), Chi-square test, and byte distributions.
Brute-force all 256 single-byte XOR keys with automated English frequency & chi-squared scoring.
Audit CSP, HSTS, X-Frame-Options, and security headers with OWASP grading (A+ to F).
Compare memory hardness, GPU ASIC resistance, and security parameters across KDF standards.
