How to convert .pfx certificate format into .key and .crt files, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

I didn't know what .pfx was before, so let's briefly explain several formats of certificates:

1. Certificate with private key

Defined by Public Key Cryptography Standards # 12 (Standard 12 of Public key encryption Technology), the PKCS#12 standard, it contains certificates in binary form of public and private keys, with pfx as the suffix name of the certificate file.

two。 Binary coded certificate

There is no private key in the certificate, and DER encodes the certificate file in binary format, with cer as the suffix of the certificate file.

3.Base64-encoded certificate

There is no private key in the certificate, and the certificate file in BASE64 format also uses cer as the suffix of the certificate file.

Now let's explain how to transfer .key and .crt files in .pfx certificate format:

Take the Linux system as an example (of course, if the openssl command is installed on Windows, it can be used normally):

Execute the following command under Linux:

(1) convert the certificate in .pfx format to .pem file format:

Openssl pkcs12-in xxx.pfx-nodes-out server.pem

(2) Export the private key server.key from the .pem file:

Openssl rsa-in server.pem-out server.key

(3) Export certificate server.crt from .pem file

Openssl x509-in server.pem-out server.crt
