Inspect PEM private key structures and encryption headers securely.
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.
Paste your -----BEGIN PRIVATE KEY----- block.
Review the format standard (PKCS#8 / PKCS#1), byte length, and encryption status.
Copy diagnostic metadata for deployment debugging.
No. Key parsing operates entirely in browser RAM and is never transmitted.
PKCS#1 is specific to RSA keys (BEGIN RSA PRIVATE KEY), while PKCS#8 is a generic standard supporting RSA, EC, and Ed25519.
Zero-egress companion tools in the Security & Network suite
Audit CSP, HSTS, X-Frame-Options, and security headers with OWASP grading (A+ to F).
Measure cryptographic randomness, Shannon entropy (0-8 bits/byte), Chi-square test, and byte distributions.
Generate secure RFC 6238 Base32 TOTP secret keys and standard otpauth:// URIs for Google Authenticator.
Construct and validate HTTP CSP headers and meta tags.
