[Python-Dev] Base-96

[Kless]

I think that would be very interesting thay Python would have a module
for working on base 96 too. [1]

It could be converted to base 96 the digests from hashlib module, and
random bytes used on crypto (to create the salt, the IV, or a key).

As you can see here [2], the printable ASCII characters are 94
(decimal code range of 33-126). So only left to add another 2
characters more; the space (code 32), and one not-printable char
(which doesn't create any problem) by last.

It's true, I didn't pay attention to that.

So the next encoding possible would of base-128 (7-bits encoding),
althought I don't know if were possible since that there would than
use non-printable characters and could change the text (by use of
chars. as Backspace or Delete).
