[RESOLVED]Digital Certificates

[Mitch_s_s]

Hi,

I am looking to publish a number of books to 5 people using 5 different machines.
i have inserted my digital certificate in the book, and trusted it on my machine
Unfortunatley as this is a self signed cert, it is currently not trusted on the other users machine (which is obvious)

what i am wondering is when i export the cert from my machine, is there anyway to export the keys also
at the moment they are currently greyed out.
out techys in work purchased a cert from verisign, but it looks as though its intended purposes is not for signing code
it is for client auth, and email sending

pricing the code signing cert from verisign i think its £600
as this is only needed for five machines, is there any way to use the self signed certificates?

sorry for the essay, any help would be appreciated

Mitch

yes, it can be done, but i think you have to create the selfcert on each machine you want to use it on, i only have one machine here at present so can't test, but i have done it before on a customers machine, can't remember if i had to sign the macro on each machine

If each workstation has Office installed then you can use each workstations selfcert.exe to create a private certificate. These certs are local to the machine only. They are generated and validated with a hardware alogorithum so moving them to other systems renders them useless.

You may need to install the selfcert utility from the Office CD as you re-run the install and select the option from the tools orcommon options.

There are cheaper certs available from other sources then verisign.

thanks for your help
i wouldnt be able to use the selfcert on each machine as you can only sign the project once
and the 5 machines will all be using the same files
thanks for the link, i will have a look at them now
the cheaper the better!

No, you can sign it multiple times. If your having trouble you can unsing it and then resign it. This must be done on each system where you generate it own local cert.

Sorry to be a pain, Just so i understand this correctly
the project can have multiple certificates attached to it at once?

i'll have a play around now, as in VBA it only seems to allow me to attach one cert :s

[RobDog888]

No, just one cert at a time. If you generate a private local cert on each system with selfcert and then on that system sign the project it will work. Then replicate the process of cert generation and signing on each of the other systems one at a time, each one unique and different cert from the others.

Sorry to resurrect and old topic, I have now purchased a cert from instantssl.com
Is there any way to sign a project programatically?
I am asking as I have over 100 projects that need signing at it will take me some time to add the certs to each one.

If I cant, then no problem - just asking as it will save me some time.

Thanks Mitch

I dont think so. If there is I would think that would be a security issue but cant say I have ever come across any functions for signing projects. Im sure I may have seen it if there was one.

looks like i'm going to get RSI ha!

thanks anyway

try recording a macro to see if there is code to do it
