 采用md5(32位小写)算法生成签名
 appKey(则一提供) + appSecret(则一提供) + timestamp(当前时间戳毫秒) + nonce(6位随机码大小写字母数子组合) + data(请求数据)
 
+### 生成签名示例
+
+```java
+public static String getMD5Lower(String input) {
+    MessageDigest md = MessageDigest.getInstance("MD5");
+    byte[] digest = md.digest(input.getBytes());
+    StringBuilder sb = new StringBuilder();
+    for (byte b : digest) {
+        String hex = Integer.toHexString(b & 0xff);
+        if (hex.length() == 1) {
+            sb.append("0");
+        }
+        sb.append(hex);
+    }
+    return sb.toString();
+}
+```
+
 ## 数据加密
 
 数据加密采用AES算法
 加密模式： CBC
 填充方式：PKCS5Padding
 偏移量：iv(则一提供)
-加密内容：appKey(则一提供) + timestamp(当前时间戳毫秒) + nonce(6位随机码大小写字母数子组合) + data(加密数据)
-密钥： appSecret(则一提供)
+加密内容：data(加密数据)
+密钥：appSecret(则一提供)
 输出：base64
 字符集：utf-8
 注：无敏感数据则无需加密
 
+### 数据加密示例
+
+```java
+public static String aesEncrypt(String source, String secret) {
+    Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
+    SecretKeySpec keySpec = new SecretKeySpec(secret.getBytes(), "AES");
+    IvParameterSpec ivSpec = new IvParameterSpec(IV_BYTES);
+    byte[] byteContent = source.getBytes("UTF-8");
+    cipher.init(1, keySpec, ivSpec);
+    byte[] result = cipher.doFinal(byteContent);
+    return Base64.getEncoder().encodeToString(result);
+}
+```
