使用场景
- 使用接口时，业务参数需要通过本文指定的加密形式进行加密传输，接口回调结果亦按照相同的加密方式反馈。
- 加密方法为Base64编码，使用CBC模式256位的AES加密
- 需要使用平台分配给商户的秘钥AccessKeySecret，一个IV向量值ivStr,向量值可增加加密算法的强度
- 参与加密的JSON字符串不能包含换行符（/n）,空格（/t）,涉及到url的参数请注意不要包含转义字符，否则解密可能发生异常
- 加密生成的字符格式默认使用UTF-8，先做Base64.encode，然后再做URLEncoder.encode，最终得到加密字符串
- 加密向量值 iv 默认为：0000000000000000（16个阿拉伯数字0）
示例
- 加密代码示例
try {
//指定加密计算方式
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
String jsonParam = WorkerSassVerifyUtil.buildMapToSign(params);
byte[] raw = secret.getBytes();
SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
IvParameterSpec iv = new IvParameterSpec(ivStr.getBytes());
cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
//获取加密字符
byte[] encrypted = cipher.doFinal(jsonParam.getBytes("UTF-8"));
//先进行Base64Encode
String enString = Base64.encode(encrypted);
//最后URLEncode
return URLEncoder.encode(enString);
} catch (Exception e) {
System.out.println("AES加密异常" + e);
}
return "";
- 解密代码示例
try {
byte[] raw = secret.getBytes("ASCII");
SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
IvParameterSpec iv = new IvParameterSpec(ivStr.getBytes());
cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);
String tempStr = URLDecoder.decode(aesData);
byte[] encrypted1 = Base64.decode(tempStr);
byte[] original = cipher.doFinal(encrypted1);
String jsonParam = new String(original, "UTF-8");
return jsonParam;
} catch (Exception e) {
System.out.println("AES解密异常" + e);
}
return "";
