Subject: make-secnet-sites: Prepare for multiple public key types
X-Git-Tag: v0.6.0~102
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=secnet.git;a=commitdiff_plain;h=79b8d68a8b64c76d929d776570afba963ae44647

make-secnet-sites: Prepare for multiple public key types

* Introduce a general base typee for public keys.

* Indirect public key object construction through a function
  which is suitable for passing to listof(), and which will
  despatch appropriately.  This allows a heterogenous list.
