java生成RSA公私钥字符串，简单易懂

解决方法：

1.下载bcprov-jdk16-140.jar包，参考：http://www.yayihouse.com/yayishuwu/chapter/1537

2.java代码

KeyPairGenerator keyPairGenerator = KeyPairGenerator

.getInstance("RSA");

keyPairGenerator.initialize(2048);

KeyPair keyPair = keyPairGenerator.generateKeyPair();

RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();

RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();

System.out.println("公钥："+new BASE64Encoder().encodeBuffer(publicKey.getEncoded()));

System.out.println("私钥："+new BASE64Encoder().encodeBuffer(privateKey.getEncoded()));
