What this tool is good for
This converter helps you move RSA public and private keys between PEM and XML formats. XML-formatted RSA keys are especially common in older C# and .NET workflows.
All conversion happens locally in the browser, so no uploaded key material is sent to the server.
Typical use cases
- Move RSA keys from OpenSSL-style PEM files into XML expected by a .NET system.
- Convert XML-formatted keys back into PEM for broader tooling compatibility.
- Inspect whether a given key is public, private, or password-protected before deployment.
Common mistakes
- Make sure the selected key type matches the actual key content.
- Password-protected private keys require the correct password before they can be converted.
- Malformed XML or incomplete RSA fields prevent XML-to-PEM conversion.
