用JavaScript通过C++用证书数字签署VBA代码项目

您可以使用Aspose.Cells及其VbaProject.sign(DigitalSignature)方法对VBA代码项目进行数字签名。请按照以下步骤检查您的Excel文件是否已用证书进行数字签名。

从“开发人员”选项卡中单击“Visual Basic”以打开“Visual Basic for Applications IDE”
从“Visual Basic for Applications IDE”中单击“工具” > “数字签名…”

将显示“数字签名表单”，显示文档是否已使用证书进行数字签名。

用JavaScript用证书数字签署VBA代码项目

以下示例代码演示了如何使用VbaProject.sign(DigitalSignature)方法。这是示例代码的输入和输出文件。你可以使用任何Excel文件和任何证书来测试此代码。

用于示例代码的源Excel文件
示例pfx文件用于创建数字签名。请在计算机上安装它以运行此代码。其密码为1234。
