PFX/P12 to PEM Converter | JavaInUse Security Tools
Crack open PFX/P12 bundles securely
Upload a password-protected archive, choose how the extracted key should be protected, and decide whether you want just the leaf certificate or the full chain. The tool runs openssl with strict, auditable flags and destroys every workspace after download.

Why operators trust this path
CLI parity. Openssl `pkcs12`, `rsa`, and `x509` are invoked exactly as you would type them, ensuring predictable output.
Workspace cleanup. Uploaded bundles and intermediate DER/PEM files are written to an isolated folder and deleted right after streaming artifacts.
Strict vs. best-effort. Strict mode aborts when multiple keys are present; best-effort trims to the first and logs warnings.
Chain intelligence. Toggle whether you want leaf-only downloads or full CA bundles; the UI surfaces when a chain is missing.
