Need a cert for digitally signing documents

[JaredBusch]

I would like to have the option to use a valid certificate to digitally sign a document.

LibreOffice fully support this, and it is easy to create a self signed certificate for this purpose.

But I was wondering if there was a service out there that let people create certs for this purpose. StartSSL had this, but they are no longer valid to use.

I have heard of CAcert, but the https version of their website fails, so screw that.

Microsoft has some details regarding this, are you only looking for free solutions or are you open to purchasing a cert for your purposes.

They have self signed and partner details on their website.

Comodo used to have a free one; I haven't used them in years though

They have a free S/Mime for email.

Maybe send a request to LetsEncrypt.org to support document signing cert services.

If you have a MS CA going, you can do this easily by adding document signing to your existing user certificate template here:

But for 3rd party stuff, a quick search brought up "Entrust"... but I've never used them and don't know how they are:

I used Identrust back when I had to do things for the government. They have pretty robust solutions. Their technology isn't always cutting edge, but it will be supported by everything: https://www.identrust.com/certificates/trustid.html.

CAcert

I used CAcert in my lab, but that was for ordinary web SSL certificates. From what I know, they offer their free CA, but all web browsers warn about connection not being secure enough or at all.
Comodo offers free email certificates, but I am not 100% sure this is what you are looking for. Just check this https://www.comodo.com/home/email-security/free-email-certificate.php
Ascertia claims to offer free short-time and cheap long-time certificates, including those for signing docs. https://account.ascertia.com/onlineCA/default

Thanks for your suggestions. Taking the results to my client.
