+# 安卓签名
+  每次安装/升级软件必须使用同一个签名，否则会将本地数据全部清空。   
+## 1. 生成密钥库文件
+  使用keytool命令生成
+```cmd
+keytool -genkey -v -keystore android/app/my-release-key.keystore -alias my-key -keyalg RSA -keysize 2048 -validity 10000
+```
+
+  根据提示输入相应信息。   
+  my.keystore为自定义名称。生成后的文件位于android/app/文件夹内
+
+## 2. 配置key.properties
+  在android文件夹内新建key.properties文件，并配置信息
+```properties
+# 密钥库文件的密码
+storePassword=12345678
+# 密钥本身的密码
+keyPassword=12345678
+# 密钥的别名，在密钥库中标识具体的密钥
+keyAlias=my-key
+# 密钥库文件相对于本配置文件的路径
+storeFile=my-release-key.keystore
+```
+
+## 3. 配置build.gradle.kts
+```kts
+import java.util.Properties
+import java.io.FileInputStream
+
+// 从根路径加载密钥属性
+val keystoreProperties = Properties()
+val keystorePropertiesFile = rootProject.file("key.properties")
+if (keystorePropertiesFile.exists()) {
+    keystoreProperties.load(FileInputStream(keystorePropertiesFile))
+}
+```
+
+  在android块内新增签名配置
+```kts
+android {
+  // 签名配置
+    signingConfigs {
+        create("release") {
+            if (keystorePropertiesFile.exists()) {
+                keyAlias = keystoreProperties.getProperty("keyAlias")
+                keyPassword = keystoreProperties.getProperty("keyPassword")
+                storeFile = file(keystoreProperties.getProperty("storeFile"))
+                storePassword = keystoreProperties.getProperty("storePassword")
+            }
+        }
+    }
+
+    buildTypes {
+
+      release {
+          signingConfig = if (keystorePropertiesFile.exists()) {
+              // 使用发布签名
+              signingConfigs.getByName("release")  
+          } else {
+              // 使用默认签名
+              signingConfigs.getByName("debug")
+          }
+      }
+    }
+}
+```
+
+  打包为release包时即可生效签名。     
+> [!CAUTION]
+> 禁止将签名文件上传到Git仓库中。
