JS端RSA加密，JAVA端RSA解密

最近做项目走的是http协议，密码明文暴露有些不安全，如是自己加密再传输

首先利用openssh生成rsa钥匙对，然后 

JS端核心代码，公匙加密，此处钥匙代头尾

var encrypt = new JSEncrypt();
//encrypt.setPrivateKey('-----BEGIN RSA PRIVATE KEY-----'+PRIVATE_KEY+'-----END RSA PRIVATE KEY-----');
encrypt.setPublicKey(pub_key);
		
var encrypted = encrypt.encrypt(a);
		
//console.log(encrypted);

JAVA端核心代码，私匙解密 （privateKey不带RSA钥匙的头尾）,此处用的是PKCS8格式

public static String decrypt(String str, String privateKey) throws Exception{
		//64位解码加密后的字符串
		byte[] inputByte = Base64.decodeBase64(str.getBytes("UTF-8"));
		//base64编码的私钥
		byte[] decoded = Base64.decodeBase64(privateKey);  
        RSAPrivateKey priKey = (RSAPrivateKey) KeyFactory.getInstance("RSA").generatePrivate(new PKCS8EncodedKeySpec(decoded));  
		//RSA解密
		Cipher cipher = Cipher.getInstance("RSA");
		cipher.init(Cipher.DECRYPT_MODE, priKey);
		String outStr = new String(cipher.doFinal(inputByte));
		return outStr;
}
