Benchmark hardware execution times and calculate optimal bcrypt password hashing rounds.
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.
Run the client-side CPU profiler to gauge hardware baseline.
Compare iteration counts, estimated milliseconds, and OWASP security ratings.
Select the cost factor matching your 250ms–500ms server response budget.
OWASP recommends a minimum cost factor of 10 to 12 for web application logins.
Each increment of 1 doubles the required hashing work and CPU execution time (2^cost).
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.
