[New-bugs-announce] [issue10430] _sha.sha().digest() method is endian-sensitive. and hexdigest()

[Kristján Valur Jónsson]

New submission from Kristján Valur Jónsson <kristjan at ccpgames.com>:

in shamodule.c, the digest() method just creates a simple bytes string of the digest.  The digest is stored as an array of 32 bit integers in the native representation.  Therefore, the digest will be different on big-  and little-endian machines.

The specification (http://en.wikipedia.org/wiki/SHA-1) suggest that the digest should actually be big endian, so the standard implementation on most home machines is actually wrong

Actually, looking at the code, hexdigest() has the same problem!
