[Zope-dev] encrypted _ac_name & _ac_password

[Declan Shanaghy]

I was wondering if my solution to the problem outlined
below
would be a useful inclusion into the main CMF code
tree?


I solved this by encrypting the __ac_name and
__ac_password values in the URL and then hacked
CookieCrumbler.py to decrypt them before it sets the
cookie.


The general idea is that the user would setup the path
to a method called decrypt as a property of the cookie
crumbler.  If this property is non NULL the cookie
crumbler calls it to decrypt the values b4 setting the
cookie, in an instance where the value is not
decrypted the decryption mechanism should return the
value passed to it.
