如果您自己生成ZIP，则可以将其创建为包并使用.NET轻松签名。

使用此：

PackageDigitalSignatureManager类（System.IO.Packaging）| Microsoft Docs [ ^ ]

If you generate the ZIP itself, you can create it as a package and easily sign it with .NET.
Use this:
PackageDigitalSignatureManager Class (System.IO.Packaging) | Microsoft Docs[^]

签名不应与ZIP文档合并，它很可能是撤回签名。所以你可以使用拉链并让某人检查信号，这通常只是一个十六进制或base64字符的进程，带有你编写的应用程序带外。

A signature shouldn't be incorporated with the ZIP document, it very well may be a "withdrawn" signature. So you could have the zip and enable somebody to check the sig, which is normally only a progression of hex or base64 characters, out of band with an application you compose.

AsymmetricAlgorithm privateKey = certificate.PrivateKey;
byte[] buffer = Encoding.Default.GetBytes(<data from the zip>);
byte[] signature = privateKey.SignData(buffer, new SHA1Managed());

and verification

AsymmetricAlgorithm privateKey = certificate.PrivateKey;
byte[] buffer = Encoding.Default.GetBytes(<data from the zip>);
byte[] signature = privateKey.SignData(buffer, new SHA1Managed());

希望这有助于你试试这个代码
