Can Acrobat DC for mobile open pdf documents that were encrypted with a certificate on the desktop version of Acrobat DC?
Currently, the Acrobat/Reader mobile products (for iOS, Android, Windows Phone) do not support encrypted PDF documents with certificates.
Other (non-Adobe) PDF viewers for iOS that I just tried on my iPad were not able to open encrypted PDF documents with certificates, either.
Sorry for the inconvenience.
