# 解密操作指南
> WaaS API 响应数据的解密操作指南
### c. 解密操作指南
本指南详细说明了如何解密从 WaaS API 获取的加密响应数据。
#### i. 解密流程步骤说明
以下是解密操作的步骤说明：
1. 从 API 响应中获取 加密数据
2. 对数据进行 Base64 解码
3. 使用 RSA公钥 进行解密
4. 将解密结果解析为 业务对象
#### ii.解密代码实例
```java DecryptionExample.java theme={null}
class DecryptionExample {
class AddressVO {
private String tenantUserId;
private String chainName;
private String address;
// TODO: Add getter and setter methods
}
public static void main(String[] args) {
try {
// ===================== 1. 获取API响应 =====================
// 发送API请求并获取响应
APIResult response = restTemplate.postForObject(
"https://waas2-out-api.powersafe-rel.cc/api/v1/api/user/getUserAddress",
httpEntity,
APIResult.class
);
// 提取加密数据（确保响应格式与API一致）
String encryptedData = response.getData();
// ===================== 2. Base64解码 =====================
// 使用Base64工具类进行解码（具体实现参考工具类）
byte[] decodedBytes = Base64Util.decodeString(encryptedData);
// ===================== 3. RSA公钥解密 =====================
// 使用与请求相同的公钥
String publicKey = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQ...";
// 执行RSA解密
byte[] decryptedBytes = RSAUtils.decryptByPublicKey(
decodedBytes,
publicKey
);
// ===================== 4. 解析业务对象 =====================
// 将解密后的JSON数据转换为业务对象
AddressVO address = JsonUtils.fromJson(
new String(decryptedBytes, StandardCharsets.UTF_8),
AddressVO.class
);
// ===================== 5. 使用解密数据 =====================
System.out.println("解析得到的地址信息:");
System.out.println("商户用户ID: " + address.getTenantUserId());
System.out.println("链名称: " + address.getChainName());
System.out.println("钱包地址: " + address.getAddress());
} catch (Exception e) {
System.err.println("\n解密过程中发生错误: " + e.getMessage());
e.printStackTrace();
}
}
}
```
