pfx-表示个人交换格式。它用于在单个文件中交换公共和私有对象。可以从.cer文件创建pfx文件。也可以用来创建软件发行商证书。

，但是没有人说何时应该使用CERT文件以及何时应该使用PFX文件。如果可能的话，请讨论我们应该何时使用CERT文件的情况。什么时候应该去找PFX文件。

but nobody is saying when we should use CERT file and when we should use PFX file. If possible please discuss the situation when we should go for CERT file & when we should go for PFX file. Thanks.

推荐答案

.pfx包含相关证书的公钥和私钥（切勿在组织外部共享）；它可用于网站上的TLS / SSL，对消息或授权令牌进行数字签名，或用于对伙伴系统进行身份验证。 .cer文件仅具有公共密钥（这是您通常与集成合作伙伴交换的密钥）；它可以用来验证令牌或客户端身份验证请求，它是HTTP客户端通过SSL握手从服务器接收到的内容。

A .pfx includes both the public and private key for the associated certificate (NEVER share this outside your organization); it can be used for TLS/SSL on web site, for digitally signing messages or authorization tokens, or for authenticating to a partner system. A .cer file only has the public key (this is what you typically exchange with integration partners); it can be used to verify tokens or client authentication requests, and it is what is received by an HTTP client from a server in the SSL handshake.
