I need to record signed acknowledgements that a user has read a file.
I can create an MD5 file that records the hash of the file easily enough. Then I want to have the user apply their digital signature to the md5 hash and store that output in a database. I cannot find how to generate the signed output.
Basically I need something similar to the vbs code signing facility. That actually works if I change the md5 file extension to vbs but that is obviously a very clumsy way to achieve it.
I then also need to check the signature against the original md5 hash to verify that was the document they signed.
Much like signing and verifying a Word document with a digital signature but only signing the md5 hash.
Any advice much appreciated.
