前端node-rsa公钥加密 java私钥解密有没有做过的大神，找了好久，没有找到资料，求源码

[Eric.CHEN]

JAVA加密：

	private static String encryptString(String valPair, String yY_KEY1) {

		byte[] ciphterText = null;
		
		byte[] keyBytes = null;
		try {
			keyBytes = (new BASE64Decoder()).decodeBuffer(yY_KEY1);
		} catch (IOException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}

		X509EncodedKeySpec spec = new X509EncodedKeySpec(keyBytes);
		KeyFactory kf;
		try {
			Cipher cipher = Cipher.getInstance("RSA");

			kf = KeyFactory.getInstance("RSA");
			RSAPublicKey pubKey = (RSAPublicKey) kf.generatePublic(spec);
			cipher.init(Cipher.ENCRYPT_MODE, pubKey);
			byte[] valPairBytes = valPair.getBytes();
			if(valPairBytes.length >= 254){
				byte[] limitedBytes = new byte[254];
				System.arraycopy(valPairBytes, 0, limitedBytes, 0, 254);
				ciphterText = cipher.doFinal(limitedBytes);
			}else{
				ciphterText = cipher.doFinal(valPairBytes);
			}
		} catch (NoSuchAlgorithmException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InvalidKeySpecException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalBlockSizeException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (BadPaddingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InvalidKeyException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (NoSuchPaddingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		return Base64.encodeBase64String(ciphterText);
	}

NodeJS解密：

if(private_key == "NA"){
			private_key = new NodeRSA(fs.readFileSync(__dirname + "/key.pem"));
			private_key.setOptions({encryptionScheme: 'pkcs1'});
		}
		
		var mac_address = private_key.decrypt(req.body.MACAddress, 'utf8');
		var computer_name = private_key.decrypt(req.body.ComputerName, 'utf8');
		
		console.log(mac_address);
		console.log(computer_name);
