[英]PhpSpreadsheet - Can I add digital signature to xls file in PHP?
I use https://github.com/PHPOffice/PhpSpreadsheet I need to add digital signature to xls document to verify authenticity of document. 我使用https://github.com/PHPOffice/PhpSpreadsheet,我需要向xls文档添加数字签名以验证文档的真实性。 Is it possible with this or maybe other PHP library?
这个或其他PHP库是否可能? Can anyone point me a direction how to do this?
谁能指出我该怎么做的方向?
Digital signatures are not supported in PhpSpreadsheet. PhpSpreadsheet不支持数字签名。
But in case you want macros signed with a certificate, then those are supported in PhpSpreadsheet Xlsx writer. 但是,如果要使用证书签名的宏,则PhpSpreadsheet Xlsx writer支持这些宏。 But that feature is not documented.
但是没有记录该功能。 To understand how to use, refer to the commit that introduced it .
要了解如何使用,请参考引入它的提交 。 It should be something like:
应该是这样的:
$spreadsheet->setMacrosCertificate($certificate); $数据表单> setMacrosCertificate($证书);
