Let's start from PEM files, which are your digital certificates written in form encoded in only basic ASCII characters, they can be easily copy&pasted, e-mailed, printed. 让我们从PEM文件开始，它们是您的数字证书，仅以基本ASCII字符编码的形式编写，可以轻松地复制，粘贴，通过电子邮件发送，打印。 More about them: 有关它们的更多信息：

The file with .crt extension is PEM or DER, which is just binary encoded certificate. 扩展名为.crt的文件是PEM或DER，它只是二进制编码的证书。 This extension is recognized by Windows, while PEM or DER aren't. Windows可以识别此扩展名，而PEM或DER无法识别此扩展名。

The file with .key extension is just your private key. 扩展名为.key的文件只是您的私钥。 It's stored in separate file. 它存储在单独的文件中。 Format not standardized. 格式不规范。

You will find more information about all these formats in the answer on serverfault: What is a PEM file and how does it differ from other OpenSSL generated key file formats? 您可以在serverfault的答案中找到有关所有这些格式的更多信息：什么是PEM文件，它与其他OpenSSL生成的密钥文件格式有何不同？
