获取“原因：无法解密安全内容条目：javax.crypto.BadPaddingException：给定最终块未正确填充”

【问题标题】：Getting "Cause: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded"获取“原因：无法解密安全内容条目：javax.crypto.BadPaddingException：给定最终块未正确填充”

【问题描述】：

我正在尝试测试 LibGDX 开发，但在尝试让最基本的应用程序在我的 android 手机上运行时遇到错误，因为我的密钥库或它的使用方式存在问题，我'不确定到底是什么问题。

在更详细地描述问题和我尝试过的问题之前，我将首先描述一些关于我的环境的事情：

我正在使用：

 - `Android Studio 3.1.4,`              with
 - `Gradle 4.6`                         inside of it, my os is
 - `Linux Mint 18.1 (Serena)            (which is based on...
 -  `Ubuntu 16.04`,                     my kernel is 
 -  `Linux 4.4.0-53-generic`.

为了解决这个问题，我多次生成了一个新的keypasss, sometimes using the command line, and sometimes through Android Studio's "Build" -> "Generate Signed APK" -> "Create New..."选项。

我生成的最新版本是使用“Build" -> "Generate Signed SPK" -> "Create New..."”选项

然后经过一番挣扎，我最终意识到我必须将我的密钥库添加到我的 gradle 文件中，这是我做错的第一件事，我最终偶然发现了 "File" -> "Project Structure" -> "android" -> "Signing" 选项，点击了绿色“ +”号并填写名称、“密钥别名”、“密钥密码”、“存储文件”和“存储密码”，确保它们与我创建的最新密钥密码匹配。

创建签名后，我选择它，然后单击“确定”，然后在我的 gradle 文件中看到它确实已添加到我的 gradle android 模块中

我将 gradle 文件与我的应用重新同步，然后清理了我的应用。

但是，当我尝试重建我的应用程序或运行它并单击通过我插入的 Android 手机运行它的选项时，我收到错误消息：

Cause: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded

我已经进行了一些研究以尝试解决此问题，一种可能是我使用了错误的密码，但此后我一直小心确保我使用了正确的密码，但这并没有解决问题。

我在做一些研究后发现的另一种可能性是，密钥库的密码有一定的规则，我认为不使用特殊字符就是其中之一，所以我确保我遵守了这条规则。

但我也知道有 2 个不同的密码，也许它们有不同的规则，但我不确定这是我的问题，我认为是其他问题。

非常感谢帮助解决此签名问题，非常感谢。

编辑：我将添加一些我的 gradle 文件内容：

【问题讨论】：

  • 另外，如果那个人因为格式问题而否决并投票结束我的问题，那是因为我正在添加一些内容和一些文件内容，这应该是被缩进，最终没有正确缩进，所以我在编辑时返回并修复格式，也许这个人实际上可以等到我完成修复格式问题，然后等待一段时间。跨度>
  • 实际上，我发现了一些东西，尽管我将 gradle 设置为使用我制作的最新密钥库，但我发现它仍在尝试完全使用来自 /home/.android/debug 的不同密钥库。密钥库，我真的不知道为什么，我将另一个 kystore 放在了 android gradle 模块中，而我的 gradle 中的任何地方都没有那个 .android/debug.keystore，所以它不应该使用它。

标签： android android-studio keystore android-keystore badpaddingexception


【解决方案1】：

我的解决方案：

1.- 在 Android Studio 4.0.1 中：构建/生成签名构建/APK 在没有的情况下生成新的密钥库，把所有的参数都放好。

2.- 一旦您已经拥有密钥库，就可以使用与第 1 点相同的密码和别名生成 APK 的签名版本

3.- 我选择调试并启用检查：V2（完整 APK 签名）并按下按钮完成

4.- 最后，在文件/项目结构中，转到模块/签名配置并再次对参数进行数字化，然后确定。

按照 Android Studio 中的这些步骤，我可以毫无问题地将我的应用部署到我的 AVD 中。

问候和快乐的编码伙伴。

    【解决方案2】：

    好吧，我发现了问题，我只是错过了一个额外的步骤，我不得不去“项目属性”下的“构建类型” - >模块：android，然后选择密钥库，我以为我已经选择了，通过在签名下突出显示它。
