[liberationtech] My CPJ blog: Lessons from the Cryptocat debate

Hey all,

  Personal feelings aside, there seem to be some problems with the article.
For one, much of the criticism focused around using a web browser alone
(without a plugin or standalone application). Now that it's served entirely
via plugin, those criticisms are no longer on the table.

  That some people criticize cryptocat for using SSL seems very
disingenuous, as we rely on SSL to help secure everything from bank
accounts to email. On top of that, Cryptocat now uses OTR, which is the
gold standard in real-time communication encryption.  It's only slight
hyperbole to say that everyone uses OTR-encrypted chat, though usually
coupled with Pidgin or Adium.  The much-lauded TextSecure also used OTR for
its encryption process.  Chat is not dramatically more secure when it's
done from a stand-alone application.

  If it seems like I'm nit-picking, it's because there are a lot of nits to
pick.  And it's not just with this piece or with pieces about cryptocat.
 This is a consistent problem with tech journalism as a whole, where apps
are created, audited, patched, audited again, and reworked, making
fact-checking more difficult.  If criticisms ABCD are present in version
1.0, and only criticism D applies in version 1.5, then talking about ABCD
as if they were still active concerns is not only incorrect, but is a very
sensitive topic for developers.

  And frankly, the use of past-tense to describe Cryptocat seems a bit...
harsh (even if that wasn't your intention).  It's still a solid app, still
under development, and still used by a lot of very passionate users.

Best,
Griffin Boyce
