如何使用Java生成电子邮件以获取公钥和私钥

Question

I want to get public key like this. 我想要这样的公钥。 Is java can do it? 是Java可以做到吗？ for example i input name, email, and password. 例如，我输入名称，电子邮件和密码。 so java generate it's to public and private key. 因此，java生成了它的公共和私有密钥。 this example of public key 此公钥示例

You can do this with the Bouncy Castle Crypto APIs, https://www.bouncycastle.org . 您可以使用Bouncy Castle Crypto API（ https://www.bouncycastle.org）进行此操作。

KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA");
keyGen.initialize(1024);
KeyPair key = keyGen.generateKeyPair();
PrivateKey priv = key.getPrivate();
PublicKey pub = key.getPublic();
String privateKey = new String(Base64.encode(priv.getEncoded(), 0,priv.getEncoded().length, Base64.NO_WRAP));
String publicKey1 = new String(Base64.encode(pub.getEncoded(), 0,pub.getEncoded().length, Base64.NO_WRAP));
String publicKey = new String(Base64.encode(publicKey1.getBytes(),0, publicKey1.getBytes().length, Base64.NO_WRAP));

As far as adding things like name, email and password, you are referring to generating a certificate, which requires that a key pair is generated. 至于添加名称，电子邮件和密码之类的内容，您指的是生成证书，这要求生成密钥对。 Certificate types vary depending on usage, as does the means to generate them. 证书类型取决于用法，生成方法也不同。

If you wish to truly secure communications, http://www.amazon.com/Applied-Cryptography-Protocols-Algorithms-Source/dp/0471117099/ is an important read, since poorly generated certificate and key exchanges are worse than no cryptography at all. 如果您希望真正保护通信安全，请阅读http://www.amazon.com/Applied-Cryptography-Protocols-Algorithms-Source/dp/0471117099/ ，因为生成不良的证书和密钥交换比没有加密时更糟所有。
