Category: Aycryption Group: None >Status: Closed >Resolution: Rejected Priority: 3 Private: No Submitted By: Sean Dague (sdague) Assigned to: Nobody/Anonymous (nobody) Summary: aycryption on large messages Initial Comment: If the messages size is too large (over about 400 characters), then aycryption fails. It just produces either: (null) [Got an uncrypted message with no signature.] or the GPG start header -----BEGIN PGP MESSAGE----- Version: GnuPG v1.2.2 (GNU/Linux) with part of an encrypted message after it I can provide sample text that works and fails if needed, but copying something from any website usually will put it over the edge if its more than 1 paragraph. ---------------------------------------------------------------------- >Comment By: Siddhesh Poyarekar (siddheshp) Date: 2010-10-03 16:58 Message: This is not possible due to service message length limits. ---------------------------------------------------------------------- Comment By: Colin Leroy (colinleroy) Date: 2003-05-31 15:16 Message: Logged In: YES user_id=460566 I enlarged some static buffers. Maybe it'll be better. Still if a message is longer than service-allowed maximum it will fail. Dunno how to fix it cleanly... ---------------------------------------------------------------------- Comment By: Ben Reser (breser) Date: 2003-05-31 11:42 Message: Logged In: YES user_id=35590 The issue is not unique to MSN. AIM does it too. I don't think it's random. ---------------------------------------------------------------------- Comment By: Colin Leroy (colinleroy) Date: 2003-05-31 06:17 Message: Logged In: YES user_id=460566 does it happen when using MSN or other service ? I noticed MSN server seems to randomly truncate messages containing "---- BEGIN PGP MESSAGE". ---------------------------------------------------------------------- Comment By: Ben Reser (breser) Date: 2003-05-31 05:17 Message: Logged In: YES user_id=35590 I'm not sure these are the same issue... The first one is what was displayed when kopete was modifying the message with <br/>'s so if your'e trying to interoperate with kopete you'll need the patch that is in CVS. The issue with size isn't so much about the size of your text but a couple of factors. The amount of text, if you have encryption and/or signing turned on, the size of the person who's key your are sending to if encrypting, and the size of your key if signing. Unfortunately what I believe is happening is that the message when encrypted/signed exceeds the size of the maximum message for the service you are using. Work arounds would be, have users decrease their key lengths, don't use signing but only encryption or vice versa depending on what your requirements are, try to type shorter messages... Ultimately the solution will be to either spit out an error message that the message is too long or find some way of splitting the message and then putting it back together. The latter will likely break interoperability with kopete unless wih cordinate with them. I haven't had a chance to see what they do (if anything) about this problem. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=550744&aid=746397&group_id=77614 |
