Learn how to configure Adobe Acrobat to search and import certificates from the Windows certificate store.
You can set up Acrobat to search for and import digital certificates from the Windows Certificate Store. This allows you to use certificates already stored in Windows to securely sign and encrypt PDF documents directly within Acrobat.
For better security, avoid importing certificates from the Windows store unless your workflow specifically requires it.
