Frequently Asked Questions

Find Quick Answers

What is a PFX file?

A PFX file (also known as PKCS#12) is a binary format that stores a certificate and its corresponding private key in a single encrypted file, typically used for SSL/TLS certificates and secure authentication.

What formats does this tool support?

The tool supports PEM format for certificates and private keys. Certificate files should be in X.509 PEM format (-----BEGIN CERTIFICATE-----) and private keys should be in PEM format (-----BEGIN PRIVATE KEY----- or -----BEGIN RSA PRIVATE KEY-----).

Is my data secure?

Yes, the tool processes your certificate and private key entirely in your browser using Web Crypto API when possible. For fallback server-side processing, data is transmitted securely and not stored permanently.

Can I use the generated PFX file for SSL certificates?

Yes, PFX files generated by this tool are standard PKCS#12 files that can be used for SSL/TLS certificates, code signing certificates, and other security applications that require certificate and private key bundling.
