no-ks-modify is a flag that asks keyservers to not accept changes to
your key (i.e. new signatures) unless they came from you.  No public
keyserver actually honors this flag, but it's part of the OpenPGP
standard so we allow setting it.

MDC is a modification detection code.  It protects messages against
certain modification attacks.
