Re: partial packet lengths in PGP 8

2003-04-11 12:10:08

Perhaps it's my flakey memory, but I recall that when Colin and
I were working on PGP3/5, when we were designing what eventually
turned into 2440, we had some packets that required a 2-bit LoL
implementation due to compatibility reasons with PGP 2.x...  I
could be totally off my rocker, here -- this work was done 8 years
ago so it's been a while and I've tried to forget that part of my
life ;)

IIRC signature packets MUST use a determinate length and are limited
to about 8192 bytes (unless this was changed somewhere along the
line).

The current draft does require that they be determinate, but I don't
see a numeric limit.  There are hard limits to the hashed and unhashed
subpackets (2^16-1 each) and (arguably) practical limits to the size of
the MPIs that form the signature, but that comes to well more than 8192.
