<PRE>Hi Dwayne,
Thanks, that is what I was assuming. If we move import/export to Crypto.IO
it will break backwards compatibility, no? Is that important?
Is anyone working on this issue? If backwards compatibility is important I
say keep what we have there now (2.6) and have a deprecation comment and/or
stderr output?
Also does Pycrypto have deprecation/error transition plan? To ease
transition some packages first do a deprecation warning, second major
release it becomes an error/exception, then third major release the code is
completely removed. Would that work with pycrypto users?
Your thoughts?
Thanks!
Kurt
