Printing Digital signatures

Post by marshall1727 »

Hello all,

sending and receiveng meggages with personal digital signatures attaches (.pfx .pk12, not pgp style) is working just fine in TB for long time and there is no problem with that. But here is a thing.

We often print email to put them in paper file, expecially when communicating with authorities. Some time back, when such email was printed, it printed a notice, that there is "attachment" in form of signature file like "smime.p7s" or something. But is there a way that TB or some add-on would process an information in the signature and print them? Like a summary saying something like:

Code: Select all

Attached signature of: xxxx@xxxxx.xx
Date : 
Holder :
Organisation : 
Signature is consedered valid / invalid
The part where validating the signature is TB doing anyway and the rest is readable.

Thank you,

I don't know of a way to do that. What is your criteria for whether a signature is valid? That it gets displayed without errors?

A quick search of https://addons.mozilla.org/en-US/thunderbird/ didn't find an add-on to do that.

You might be able to write a message filter that executes some javascript to print the message and then parse and validate the signature , and print some information about it being validated. That would require the FiltaQuilla add-on at https://addons.mozilla.org/en-US/thunde ... ltaquilla/, plus figuring out what javascript to execute .

Messages for each folder are stored in mbox files. For example, all of the messages for the inbox folder are stored in the "inbox." file. Scripts or other programs can parse the contents of the mbox files (they're just 7-bit ASCII text files that follow industry standards for how they store the mail messages) and do stuff to the messages. However, I don't know of any scripts that do what you want.
