Class: PublicSubkeyPacket

PublicSubkeyPacket(dateopt, configopt)

A Public-Subkey packet (tag 14) has exactly the same format as a Public-Key packet, but denotes a subkey. One or more subkeys may be associated with a top-level key. By convention, the top-level key provides signature services, and the subkeys provide encryption services.

Constructor
