Why can't I pickle a md5 object? Is it because md5 algorithm needs to
read 512-bits at a time?
I need to md5() some stream, pause(python.exe quits), and resume
later. It seems that the md5 and hashlib in std module could not be
serialized?
Do I have to implement md5 algorithm again for this special occasion?
Or is there anyway to assige a digest when creating md5 objects?
