Is there a way to get the file signature of a file inside a document? I tried checking the Embedded Object Class but it seems that there is no function for getting the file signature. Is there a way to get it just by using lotus script?
If not then I believe I'll need to maybe use a java class agent right? Can you provide a link that is doing this function or maybe can you guide me with some codes for this one. I am familiar with java but when it is being used in lotus notes agents I am not much familiar with the class being used.
Basically what I need to do is check the files in the documents and check if they are a valid file with the valid signature. Just checking the extension name is not enough as it might be renamed but the signature of the file is not valid so I'll need to confirm the file signature in checking. Thanks.
You have to write the file to file system and then you can read the file from there. Use a temp directory and delete every file after usage.
Look here for code to write attachments to file system as a starting point. Property EmbeddedObjects is available for documents too in case you want to analyse all attachments of a document.
You can accomplish the same in Java. Just look for Java classes in Language cross-reference in documentation.
