Calculate key derivation rounds, server hashing latency, and GPU crack resistance (OWASP compliant).
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.
Drag the slider between rounds 4 and 20.
Inspect the calculated 2^cost rounds and estimated execution time.
Review the security level and architecture recommendations.
OWASP recommends a minimum work factor of 12 (or 13-14 for high-security applications), targeting 250ms to 1000ms server calculation time.
Bcrypt requires 4 KB of memory per thread with continuous blowfish key expansion, which limits GPU parallel throughput compared to raw SHA-256.
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.
