Summary: Error in base64.b32decode
Initial Comment:
Hi,
I believe there is an error in base64.b32decode because
it doesn't seem to
allow to decode arbitrary binary data:
<code>
#!/usr/bin/env python2.4
import base64
b64d = base64.b64decode
b64e = base64.b64encode
print "base64: ", repr(b64d(b64e('\x00')))
b16d = base64.b16decode
b16e = base64.b16encode
print "base16: ", repr(b16d(b16e('\x00')))
b32d = base64.b32decode
b32e = base64.b32encode
print "base32: ", repr(b32d(b32e('\x00')))
</code>
This raises a very strange exception:
Traceback (most recent call last):
File "test.py", line 18, in ?
print "base32: ", repr(b32d(b32e('\x00')))
File "/usr/lib/python2.4/base64.py", line 228, in
b32decode
last = binascii.unhexlify(hex(acc)[2:-1])
TypeError: Odd-length string
b32 should work just like b64 and b16.
Best regards
Frank Bensktein.

Fixed by applying patch #1171487, to both HEAD and 2.4-maint
branches. Thanks for reporting this!

Your original report somehow got larded with blank lines that
spread it over 4 screens. If you can somehow prevent this next
time, it would be much easier to read.

patch 1171487 posted. It is pure python so you should be
able to incorporate into your existing codebase relatively
easily. You won't need to rebuild the python executable.
