[英]smartcard and p12 file creation
I'm trying to create a p12 file (pkcs12). 我正在尝试创建一个p12文件(pkcs12)。 I know that i need a certificate and a private key to create it.
我知道我需要创建证书和私钥。 I read the certificate from smart card, but i have problems with private key.
我从智能卡读取了证书,但是私钥有问题。 I know that in smart card there is a private key, but i cannot extract it...is it true?
我知道智能卡中有一个私钥,但是我无法提取它……是真的吗? There is another way to use the private key stored in smart card and use it to create the p12 file?
还有另一种方法来使用存储在智能卡中的私钥并使用它来创建p12文件吗?
I want to use this code: 我想使用以下代码:
KeyStore store = KeyStore.getInstance("PKCS12");
store.load(null, null);
store.setKeyEntry("Eric's Key", privKey, null, certificate);
FileOutputStream fOut = new FileOutputStream("id.p12");
store.store(fOut, passwd);
Any suggestion please? 有什么建议吗? Thanks
谢谢
No, you generally cannot extract the private key from a Smart Card. 不,您通常无法从智能卡中提取私钥。 Sometimes there are backup or key wrapping functions available, but you would require special access for that.
有时有备份或密钥包装功能可用,但是您需要特殊的访问权限。 PKCS#12 is a binary format for storing keys and certificate, so you do require access to the private key to create one.
PKCS#12是用于存储密钥和证书的二进制格式,因此您确实需要访问私钥才能创建密钥。
