Request: PKCS#7/Cryptographic Message Syntax support

[TheGeekPharaoh]

I’d love to see support for PKCS#7/Cryptographic Message Syntax added to Perfect-Crypto. It would allow for things like signed/encrypted iOS profiles to be delivered by a Perfect-based REST endpoint. (https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/iPhoneOTAConfiguration/profile-service/profile-service.html#//apple_ref/doc/uid/TP40009505-CH2-SW37). Additionally, it would allow us to replace a HUGE amount of our existing Java code with server-side Swift. I know this functionality is supported by OpenSSL, so it may be easy to incorporate it into Perfect-Crypto.
