如何从 keystore.pkcs12 文件中获取私钥

Question

我正在尝试从密钥库文件中获取私钥，

    keyStore.load(KeyStoreinputStream, "keystorepass".toCharArray());

PrivateKey key = (PrivateKey) keyStore.getKey(alias, new char[0]);

new char[0] --> 我在生成的时候没有给私钥密码

低于异常：

java.security.UnrecoverableKeyException: Get Key failed: Given final block not properly padded
    at java.security.KeyStore.getKey(KeyStore.java:792)
Caused by: javax.crypto.BadPaddingException: Given final block not properly padded

Answer 1

new char[0] 不正确。如果没有密钥密码，使用null.
