5. Signature Management
5. 签名管理

5.1 Types of Signature
5.1 签名的类型

To download and run an application (APK) on PayDroid terminals, two signature levels are required. The first signature is performed by the application developer. The second signature is performed by PAX systems.
要在 PayDroid 终端上下载并运行应用程序 （APK），需要两个签名级别。第一个签名由应用程序开发人员执行。第二个签名由 PAX 系统执行。

Developer Signature
开发者签名

To publish an APK on Google Play Store, any developer can choose to have the signature keypair stored by Google in its systems, linked to the developer account; or to have a local keystore file containing signature public and private key. To publish an APK on MAXSTORE, the suggested method is to use a local keystore, and let Android Studio sign the APK. All the APK versions should be signed by the same developer signature.
要在 Google Play 商店发布 APK，任何开发人员都可以选择将签名密钥对由 Google 存储在其系统中，并链接到开发人员帐户;或者具有包含签名 public 和 private key 的本地密钥库文件。要在 MAXSTORE 上发布 APK，建议的方法是使用本地密钥库，并让 Android Studio 对 APK 进行签名。所有 APK 版本都应由相同的开发人员签名签名。

PAX Signature

PAX Signature is an additional level of security, specific for PayDroid/Prolin/Monitor devices.The signature relies on a private key (PVK), a public key (PUK) and a certificate, signed by PAX. During manufactory each terminal is prepared to recognize software signed with PAX PVK. Signature can be performed using PAX Partner Network (PPN).
PAX Signature 是 PayDroid/Prolin/Monitor 设备专用的附加安全级别。签名依赖于私有密钥 （PVK）、公有密钥 （PUK） 和由 PAX 签名的证书。在制造过程中，每个终端都准备好识别使用 PAX PVK 签名的软件。可以使用 PAX Partner Network （PPN） 进行签名。

Each PAX customer can request its own signature keypair. An S80 is used as HSM to generate and store the keypair. The Public Key is extracted and sent to PAX to be signed, in order to have the PUK.
每个 PAX 客户都可以请求自己的签名密钥对。 S80 用作 HSM 来生成和存储密钥对。公钥被提取并发送到 PAX 进行签名，以便获得 PUK。

Using PAX SW signature tool, the customer can sign the application using its PVK. The signed APK can run on any terminal where the related PUK has been installed.
使用 PAX SW 签名工具，客户可以使用其 PVK 对应用程序进行签名。签名的 APK 可以在安装了相关 PUK 的任何终端上运行。

In https://ppn.paxengine.com/release/releaseDetail/365588990408841216?type=1, there is a training video showing how to sign an application iwht app sign system.
在 https://ppn.paxengine.com/release/releaseDetail/365588990408841216?type=1 中，有一个培训视频展示了如何对应用程序 iwht 应用程序签名系统进行签名。

Custom PAX signature adoption
采用自定义 PAX 签名

In order to use a custom PAX Signature keypair (PUK/PVK), a signature tool shall be set-up with the custom PVK, and the custom PUK shall be installed in any terminal. There are two signature tool options
为了使用自定义 PAX Signature 密钥对 （PUK/PVK），应使用自定义 PVK 设置签名工具，并且自定义 PUK 应安装在任何终端中。有两个签名工具选项

Local signature tool
本地签名工具

Online signature tool
在线签名工具

Once the marketplace owner choose to switch to a custom signature keypair (Reseller signature), the custom PUK shall be installed in any terminal registered to the marketplace. All apps should be signed by this custom PAX Signature keypair.
一旦 Marketplace 所有者选择切换到自定义签名密钥对（经销商签名），自定义 PUK 应安装在注册到 Marketplace 的任何终端中。所有应用程序都应由此自定义 PAX Signature 密钥对签名。

In https://ppn.paxengine.com/release/releaseDetail/568202830236614656?type=1, it is recommended to use Customer PUK/PVK for application signature verification since other partner’s application also signed with unified PAX PUK can be authenticated and installed on the POS successfully.
https://ppn.paxengine.com/release/releaseDetail/568202830236614656?type=1，建议使用客户 PUK/PVK 进行应用程序签名验证，因为其他合作伙伴的应用程序也使用统一 PAX PUK 签名，可以成功验证并安装在 POS 机上。

5.1.1 How to use Custom PUK/PVK for Signature Verification
