我知道摘要是

2ZXt/8T161gL9mW1UlORjjXBvp/v1gaHausPzeQJiWw=

但是我找不到计算摘要的方法。

修改

我只是不知道要应用哪些数据进行哈希处理。

目标是将摘要放在XAdES签名上，并使用python进行。

Answer 1

摘要只是一些数据的哈希值。在您的情况下，我会根据32个字节的长度猜测其为SHA2。

该过程预计将要签名的内容散列到所谓的（消息）摘要中，然后使用证书（在您的情况下为RSA）创建摘要的签名。

要回答您的问题（但我找不到计算摘要的方法。）：对内容数据使用SHA2。

如果您提供更多详细信息-例如您肯定会使用哪种编程语言一定可以为您提供更多帮助。

编辑

我只是不知道要应用哪些数据进行哈希处理。

您要创建签名还是验证签名？听起来好像您想验证签名。那么，您是否有证书，一些数据和签名-或同时存在？你从哪里来的摘要？如果您告诉我们更多信息，我们可以为您提供进一步的帮助...

如何计算XAdES签名的签名证书的摘要？
