问题描述

是否可以将证书从智能卡复制到计算机并用它登录到特定站点.

Is it possible to copy a certificate from a smart card to the computer and use it to login to a certain site.

在Mac上，这些证书会显示在钥匙串"中，并且可以保存到磁盘，但是我不确定如何强制网站提示对话框以选择证书.连接智能卡后，将以某种方式出现提示，并要求选择证书.

On mac, those certificates appear in Keychain and they can be saved to disk, but I'm not sure how to force a site to prompt a dialog screen to choose the certificate. When the smart card is connected, the prompt somehow appears and asks to choose a certificate.

推荐答案

智能卡包含一个密钥对，该密钥对由包裹在X509证书中的私钥和公钥组成.

The smartcard contains a key pair composed by a private key and a public key wrapped into a X509 certificate.

可以将证书导出并复制到笔记本电脑，但是要识别，签名或解密，必须使用私钥.私钥通常在智能卡上生成，并且不可提取.这是卡提供的安全性的一部分:所有操作都在卡内部执行

It is possible to export the certificate and copy to your laptop but to identify, sign or decrypt it is necessary to use the private key. The private key is usually generated on the smartcard and is not extractable. This is part of the security that the card provides: All operations are performed inside the card
