Use for Signing in Reader DC

[Guest]

Hi there,

I have just been issued a Digital Certificate from Exostar FIS, for Digital Signature (as detailed in the KU extension). In the Digital ID and Trusted Certificate Settings menu I can see it, I can view it, but I can't select "Use for Signing". Why not?

Cert details:

Signature algorithm: SHA256 RSA

Validity ends: 2018/03/07

Key usage: Digital Signature

EKU: Client Authentication; 1.3.6.1.5.2.3.4

Public Key: RSA (2048 bits)

Location: Windows Cert Store

Many thanks.

Hi mdunk,

You may have to check with certificate issuer.

There have been some changes in this area.If the certificate has not a particular value the certificate won't be used for signature purposes. You may visit this page A: Changes Across Releases — Digital Signatures Guide for IT

Hi Tariq,

From the link in your response I see no reason the Exostar Certificate would not be allowed for signing. What are the criteria Reader DC uses to determine if a certificate can be used for signing? I can then confirm with the issuer if their certificate meets these requirements.

Many thanks,

Matt

Hi Matt,

Let us know how the certificate issuer respond to your query about the requirements of the certificate with Reader?
