About PFX to P12 Conversion

The .pfx and .p12 extensions both refer to the same PKCS#12 binary format - they are effectively interchangeable. This tool re-exports your archive so you get a fresh .p12 file and can optionally change the protection password in the process. It runs openssl pkcs12 on the server to unpack the bundle and repackage it, which is useful when a tool strictly expects a .p12 extension or when you need to rotate the keystore password.

Convert and package keys for SSH, TLS, and keystore workflows.
