比较java中的PublicKey对象 [英] Compare PublicKey object in java

问题描述

我有两个PublicKey对象。我想比较两者的相等性或使用java安全API或弹性城堡API来检查哪个是最新对象。我怎么能实现这个目标？

I have two PublicKey object.I want to compare both for equality or to check which is latest object using java security API or bouncy castle API.How can i achieve this?

推荐答案

您可以使用等于

if (!key.equals(copyKey)){
    System.out.println("not equals!");
}

或检查密钥的哈希码

if (key.hashCode() != copyKey.hashCode())
{
    System.out.println("public key hashCode check failed");
}

或比较两个公钥的十六进制字符串

or compare the hex string of the two public keys

String encodedKey1 = new String(Hex.encode(key1.getEncoded()));
String encodedKey2 = new String(Hex.encode(key2.getEncoded()));

if (!encodedKey1.equals(encodedKey2)){
    System.out.println("not equals!");
}

您在Bouncy Castle Tests进行了大量的重要比较和检查样本，查看一些代码的 org.bouncycastle.jce.provider.test 包。 BC不是严格必要的，你可以与默认的java安全类进行比较。

You have a lot of key comparision and check samples at Bouncy Castle Tests, take a look at the org.bouncycastle.jce.provider.test package for some code. BC is not strictly necesary you can do the comparision with the default java security classes.
