Read this before relying on the certificate tools

These tools are provided as-is, for convenience, with no warranty of accuracy or availability. Don't treat any single tool's output as the final word for a production security decision — verify anything important with your certificate authority or your server's own OpenSSL installation.

Certificate and key material

Never paste a private key into a tool you don't control, on any website, including this one. The CSR generator creates a private key in your browser session and shows it to you once — copy it immediately, since it is not stored anywhere on this server after the page is generated.

Server-dependent tools

A few tools (OCSP checker, SSL converter's PKCS#7 support) can give a more complete answer when the hosting account allows PHP's shell_exec to call the system OpenSSL binary. On hosts where that's disabled, those tools fall back to a lighter, clearly-labeled check rather than failing silently.

No data retention

Values submitted to server-side tools are processed for that single request and are not logged or stored.
