Before sending a ZIP to your device via ADB, compare its cryptographic hash against the download source to guarantee file integrity.

When your Android device receives an OTA update, it doesn't blindly trust it. The RecoverySystem.verifyPackage() API performs a cryptographic handshake: the device's built-in public key (often stored in /system/etc/security/otacerts.zip ) is used to validate the signature in the update's Zip comment. Only after this verification succeeds will the installation process even begin.

If you are building an AOSP image and need to generate the signed file, the command typically run from your build root ( updatesignedzip top

: A pair of private/public keys (usually testkey.pk8 and testkey.x509.pem ) to re-sign the output archive. Step-by-Step Usage Guide

These files are frequently encountered by developers and advanced users in several scenarios:

Android 源码编译时会自动生成签名过的 OTA 包。若你需要手动制作，通用流程如下： : Place update-signed

For engineers building custom Android Open Source Project (AOSP) distributions or system administrators managing corporate IoT devices, compiling a valid update-signed.zip requires specialized build tools. How to sign update.zip - Stack Overflow

Use zip command-line tool to create a package containing only changed or new files.

| 按键 | 作用 | |------|------| | q | 退出 top | | 1 | 展开 / 合并显示每个 CPU 核心的使用情况 | | P | 按 CPU 使用率降序排序（默认） | | M | 按内存占用降序排序 | | T | 按累计运行时间排序 | | c | 显示完整命令路径（不再是短名称） | | k | 终止一个进程（需要输入 PID） | | r | 调整进程的优先级（nice 值） | | u | 只显示某个特定用户的所有进程 | | d | 改变刷新间隔（秒，支持小数点） |

By treating every signed zip not as a casual file but as a critical system update, you protect your device integrity and enjoy a stable, secure Android experience.
