Summary
The public key encryption technology, standard 12th (Cryptography Standards #12, PKCS#12) specifies a portable format for storing and transporting user or server private keys, public keys, and certificates. It is a binary format, and these files are also called PFX files. Developers often need to convert PFX files into some different formats, such as PEM
