Digital IDs and Certificates

digital signature and certificate match the signer’s digital ID. Adobe Acrobat includes one 
handler that has access to trusted certificates in a number of different locations. The 
locations include Microsoft’s cryptographic store used for Windows security, PKCS#12 
encryption, which is a standard encryption format, and PKCS#11 encryption, which is used 
on smart cards.
Obtaining a Digital ID from a Third Party
In general, digital IDs are issued by a third party for use in any official capacity. Third-party 
providers, such as Entrust, include advanced security features. The provider of digital ID 
certificates is sometimes called a certificate authority or a signature handler. Third-party 
providers verify your identity, issue the private key, protect the public key, and maintain 
system integrity. You may want to obtain more than one digital ID if you sign documents in 
different roles or with different certification methods. See 
 for 
information on using providers with advanced security features. 
Digital IDs and the Acrobat SDK
You can work with digital IDs and certificates from Acrobat JavaScript and from a plug-in 
using the PubSec API (see 
). Using the Acrobat 
SDK, you can:
Create a digital ID (Default Certificate Security).
Save a certificate file to disk.
Use an existing certificate to create a digital ID.
Manage digital IDs (Windows Certificate Security).
Share digital ID certificates.
Build a list of trusted identities.
