我有一个服务器端代码加载 keystore 的应用程序 -
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream(keyStoreFile), "password".toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, "privatepassword".toCharArray());
SSLContext sslCtx = SSLContext.getInstance("TLS");
sslCtx.init(kmf.getKeyManagers(), null, null);
当我在 keystore 中只有一个私钥时，这工作得很好。当我向 keystore 添加另一个私钥(使用不同的密码)时，出现此错误
java.security.UnrecoverableKeyException: Cannot recover key
at sun.security.provider.KeyProtector.recover(KeyProtector.java:311)
at sun.security.provider.JavaKeyStore.engineGetKey(JavaKeyStore.java:121)

然后我尝试按照下面的链接创建自定义 key 管理器
@布鲁诺 我尝试了你给出的建议。但是，这不起作用。我的自定义 key 管理器工厂看起来像这样 -
class CustomKeyManager implements X509KeyManager {
private final KeyStore ks;
private final String alias;
public CustomKeyManager(KeyStore ks, String alias) {
this.ks = ks;
this.alias = alias;
}
@Override
public String[] getClientAliases(String paramString,
Principal[] paramArrayOfPrincipal) {
return new String[]{alias};
}
@Override
public String chooseClientAlias(String[] paramArrayOfString,
Principal[] paramArrayOfPrincipal, Socket paramSocket) {
// TODO Auto-generated method stub
return alias;
}
@Override
public String[] getServerAliases(String paramString,
Principal[] paramArrayOfPrincipal) {
// TODO Auto-generated method stub
return new String[] {alias};
}
@Override
public String chooseServerAlias(String paramString,
Principal[] paramArrayOfPrincipal, Socket paramSocket) {
// TODO Auto-generated method stub
return alias;
}
@Override
public X509Certificate[] getCertificateChain(String paramString) {
// TODO Auto-generated method stub
return null;
}
@Override
public PrivateKey getPrivateKey(String paramString) {
PrivateKey pk = null;
try { //have hardcoded this to the key i am working with
pk = (PrivateKey) ks.getKey("mykey", "privatepassword".toCharArray());
} catch (UnrecoverableKeyException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (KeyStoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return pk;
}
在我创建 CustomKeyManager 对象后，如果我调用 getPrivateKey，我会得到一个非空私钥 -
Sun RSA CRT 私钥，1024 位 modulus: 117260821110864021601500037071432398877761428124640545232618906306796101075244931231861318133902594657774603548686479580347869030216483422242066483203953111970007516384847036243243010603169399491545560497255823475630452314709747201644535089867367118834303975042348737995500693672037616900410158764770570813729 …………
这告诉我我的 getPrivateKey 正在工作。
我按以下方式使用 CustomKeyManager
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream(keyStoreFile), "password".toCharArray());
SSLContext sslCtx = SSLContext.getInstance("TLS");
CustomKeyManager ck = new CustomKeyManager(ks, "mykey");
KeyManager[] kms = new KeyManager[1];
kms[0] = ck;
System.out.println(ck.getPrivateKey("mykey")); //returns a non null value
sslCtx.init(kms , null, null); //throws an exception
我得到的异常是
javax.net.ssl.SSLHandshakeException:没有共同的密码套件
我创建和使用 CustomKeyManager 的方式是否有错误。另一件有趣的事情是，如果我为 CustomKeyManager 中的所有方法入口点设置断点，它们都不会被命中。
