Hi , I have given an ecdsa cert and its corresponding root ca paths full trust in adobe reader dc . However under usage options , i am still unable to select the cert for signing. 

What requirements of a cert is required for it to be able to be selected for signing ? or is ecdsa certs not supported ? 
The key usage for the cert has digital signature enabled and the cert is in a smart card. 

Thank you.

ECDSA certs acceptable to Acrobat must be based on one of a few named curves. What curve is your certificate using?

Here's the Acrobat Digital Signatures Guide to help you answer margueritek's question: https://www.adobe.com/devnet-docs/acrobatetk/tools/DigSigDC/standards.html

 

I would say that, if you're able to see more options from the drop down menu for the "Key Algorithm",  to select ECDSA elliptic curve P256 with digest algorithm SHA256

Is this is just for you or are you trying to isuue out such certificate to many users?

 

Also, are using a governement form?

 

 

It is supported according to this document: 

https://www.adobe.com/devnet-docs/acrobatetk/tools/DigSigDC/standards.html

 

But if you run into configuration issues you may need to do further reading on how to implement them with the Windows Server: https://community.arubanetworks.com/t5/Controller-Based-WLANs/How-to-generate-ECDSA-EC-certs/ta-p/187680

 

And do further research on the supported encryption algorithms and digest creation compatibility found in the first link that I posted above.

 

In any case, first you need to verify and test that your smart card reader works and actually has all drivers and middleware updated for your OS version.

 

Then you need to install your root and intermediate certficates in the appropriate certificate store path for your operating system.  Here is a good thorough article: https://www.thesslstore.com/blog/root-certificates-intermediate/

 

Then you need to  register in Acrobat the Identities and Trusted certificates.

 

To do so got to Edit --> Preferences--> Signatures. Click on the "More" button found in the " Identities & Trusted Certificates" section.

Hi Thank you for the reply . I have done the steps as listed above. 
The root path and intermediate certs are also installed in the respective cert stores. 

The user cert shows up in the "Windows Digital Id" section after i click on edit->preferences->Identities & Trusted Certificates->more but under "Usage Options" i am unable to select this cert for signing . 
There is no option to use it for signing whereas the other certs are able to be selected. 

It also shows that the cert is trusted . So i am not sure what other steps am I missing .

Are all of the other certificates that you can use for signing ECDSA or just the one that you're having issues with?

 

I would say , that just to rule out other trusted certificate issues, go to Edit --->> Preferences--->> "Trust Manager" and update both the "Automatic Adobe Approved Trust Lists(AATL) and the EUTL below that.
