轉換的關鍵對象專用密鑰

Question

我需要使用下面的方法從KeyStore類：

public Key getPrivateKey(String alias)

但在最後，我需要專用密鑰對象，而不是重點。我如何將Key對象轉換爲PrivateKey？ 謝謝！

Answer 1

後，您從您的密鑰存儲 密鑰的密鑰創建密鑰對，然後得到一對密鑰的酒吧和私法重點如下：

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);
