Frequently Asked Questions

Find Quick Answers

What is a PKCS12 file?

PKCS12 (Public Key Cryptography Standards #12) is a file format used to store cryptographic objects like certificates and private keys in a single, password-protected file. It's commonly used for SSL/TLS certificates and is also known as PFX files.

What formats are supported for input?

The tool accepts certificates and private keys in PEM format (text-based with BEGIN/END headers). You can paste the text directly or upload .crt, .pem, or .key files. Other formats like DER are not supported directly—convert them to PEM first.

Is my data secure?

Yes, all processing happens securely on our servers. The generated PKCS12 file is available for download only and is not stored permanently. We use industry-standard OpenSSL libraries for encryption.

Can I use this for code signing certificates?

Yes, this tool can generate PKCS12 files suitable for code signing, as long as you have the appropriate certificate and private key in PEM format.
