转换的关键对象专用密钥

Question

我需要使用下面的方法从KeyStore类：

public Key getPrivateKey(String alias)

但在最后，我需要专用密钥对象，而不是重点。我如何将Key对象转换为PrivateKey？ 谢谢！

Answer 1

后，您从您的密钥存储 密钥的密钥创建密钥对，然后得到一对密钥的酒吧和私法重点如下：

Key prvkey = keyStore.getKey(_alias,_keypass.toCharArray()); 
PublicKey pubkey = certificate.getPublicKey(); 
KeyPair keypair = new KeyPair(pubkey, (PrivateKey)prvkey); 
PrivateKey privKewy = keypair.getPrivate(); 

Answer 2

//get keystore 
//jks for type "JKS", 
//.p12 or .pfx for type "PKCS12" 
//specification name is PKCS#12, but the # is not used in the Java keystore type name 
KeyStore keystore = KeyStore.getInstance("pkcs12"); 
//load keystore - is FileImputStream to location of your pfx/jks file   
keystore.load(is, password); 
//get private key   
PrivateKey privateKey = (PrivateKey)keystore.getKey(alias, password);
