AES加密传输密文密码

1.高级加密标准(AES,Advanced Encryption Standard)为最常见的对称加密算法。对称加密算法也就是加密和解密用相同的密钥。

package cn.com.test;

import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.spec.SecretKeySpec;

import org.apache.commons.codec.binary.Base64;

import sun.misc.BASE64Decoder;

public class AES {
	private static final String KEY = "a1b2c3d4e5f6g7h8";
	private static final String ALGORITHMSTR = "AES/ECB/PKCS5Padding";

	public static void main(String[] args) throws Exception {
		String content = "123456";
		String s = aesEncrypt(content, KEY);
		System.out.println("sagfasdgfasd" + s);
		String decrypt = aesDecrypt(s, KEY);
		System.out.println("解密后：" + decrypt);
	}

	public static String base64Encode(byte[] bytes) {
		return Base64.encodeBase64String(bytes);
	}

	public static byte[] base64Decode(String base64Code) throws Exception {
		return new BASE64Decoder().decodeBuffer(base64Code);
	}

	public static byte[] aesEncryptToBytes(String content, String encryptKey) throws Exception {
		KeyGenerator kgen = KeyGenerator.getInstance("AES");
		kgen.init(128);
		Cipher cipher = Cipher.getInstance(ALGORITHMSTR);
		cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(encryptKey.getBytes(), "AES"));
		return cipher.doFinal(content.getBytes("utf-8"));
	}

	public static String aesEncrypt(String content, String encryptKey) throws Exception {
		return base64Encode(aesEncryptToBytes(content, encryptKey));
	}

	public static String aesDecryptByBytes(byte[] encryptBytes, String decryptKey) throws Exception {
		KeyGenerator kgen = KeyGenerator.getInstance("AES");
		kgen.init(128);
		Cipher cipher = Cipher.getInstance(ALGORITHMSTR);
		cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(decryptKey.getBytes(), "AES"));
		byte[] decryptBytes = cipher.doFinal(encryptBytes);
		return new String(decryptBytes);
	}

	public static String aesDecrypt(String encryptStr, String decryptKey) throws Exception {
		return aesDecryptByBytes(base64Decode(encryptStr), decryptKey);
	}
}

2.前台加密方法，需要下载一个crypto-js.min.js：

    //AES加密
    function encryptByAES(message) {
        var key = 'a1b2c3d4e5f6g7h8';
        var keyHex = CryptoJS.enc.Utf8.parse(key);
        var encrypted = CryptoJS.AES.encrypt(message, keyHex, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        return encrypted.toString();
    }
