FirmwareKit.OzipReader

NuGet License: MIT

Oppo OZIP 加密固件解析库，支持解密和提取 OZIP 加密固件包内容。

功能特性

  • 元数据读取：解析 OZIP 头部信息、条目数量、密钥标识等
  • 自动解密：检测并使用正确的 AES-128-ECB 密钥解密
  • 条目解析：枚举解密后 ZIP 内部的所有文件条目
  • 数据提取：完整解密并提取固件包内容
  • 内置密钥数据库：支持多种 Oppo 设备的自动解密
  • 密钥暴力破解：支持未知密钥的暴力枚举破解

支持的固件格式

格式 扩展名 加密算法 说明
OZIP .ozip AES-128-ECB Oppo 加密 ZIP 固件

安装说明

dotnet add package FirmwareKit.OzipReader

快速开始

读取固件元数据

using FirmwareKit.OzipReader;

// 从文件读取
var metadata = OzipReader.ReadMetadata("firmware.ozip");
Console.WriteLine($"条目数: {metadata.EntryCount}");
Console.WriteLine($"密钥标识: {metadata.KeyId}");

// 从流读取
using var stream = File.OpenRead("firmware.ozip");
var metadataFromStream = OzipReader.ReadMetadataFromStream(stream);

解析条目列表（自动解密）

using var stream = File.OpenRead("firmware.ozip");
var archive = OzipReader.Parse(stream);

foreach (var entry in archive.Entries)
{
    Console.WriteLine($"{entry.Name} - {entry.Size} bytes");
}

提取固件内容

var options = new OppExtractOptions
{
    OutputDirectory = "./output",
    Overwrite = true
};

var result = OzipReader.Extract("firmware.ozip", "./output", options);
Console.WriteLine($"提取完成: {result.SuccessfullyExtracted}/{result.TotalEntries}");

工作原理

OZIP 文件使用 AES-128-ECB 加密，每 16KB 数据块中：

  • 前 16 字节为加密数据
  • 剩余 0x3FF0 字节为明文

解密过程：

  1. 读取加密数据的前 16 字节
  2. 使用内置密钥数据库尝试解密
  3. 验证解密结果是否以有效魔术字节开头（PK\x03\x04、AVB0 或 ANDR）
  4. 使用正确的密钥解密整个文件

API 参考

核心类

类 说明
OzipReader 静态入口，提供 ReadMetadata、Parse、Extract 等方法
OzipArchive 固件归档对象，包含条目集合
OzipEntry 单个文件条目
OzipMetadata 固件元信息

加密提供者

// 使用内置密钥自动解密
var provider = new OzipFormatCryptoProvider();
var decryptedData = provider.AutoDecrypt(encryptedData);

// 使用指定密钥解密
var decryptedData = provider.Decrypt(encryptedData, "KEY_ID");
