Description Miloslav Trmač 2008-11-24 14:08:30 EST

Version-Release number of selected component (if applicable):
python-nss-0.1-1.fc10

It would be nice to be able to do the following through python-nss:
* Compute hashes incrementally (using an interface similar to Python's hashlib
  module).  Storing 100MB of data in memory only to hash it is rather wasteful.
* Compute HMAC authentication codes.

Comment 1 John Dennis 2010-04-12 10:44:04 EDT

Since this RFE was first filed python-nss has added more support for hashing, however it did not include a "feed" interface. I'm in the process of adding a number of new features to python-nss which should be available soon. I'll make sure the next release has this functionality. I may ask you to test it before I officially release it :-)

Comment 2 John Dennis 2010-04-14 15:32:23 EDT

Apparently my memory is failing me :-) This functionality was already implemented and has already been pushed out in python-nss-0.8.

see /usr/share/doc/python-nss-0.8/examples/digest_test.py for an example of how to use it.
