Frequently Asked Question:
Digital Signature: .p7c instead of .pfx file
Question
Do you support (or plan to support) using a .p7c file instead of .pfx file for generating a digital signature?
Answer
We don't currently support .p7c files for generating digital signatures, nor do we currently have plans introduce this in the short-term, but I will add this to the feature wish list and it might be something that we can add in version 8.
