Hi,

I'm trying to compile PyCrypto 2.6.1 for Chaos Calmer (targeting ar71xx), based on the Makefile/patches from the old packages feed. The library compiled without any fatal errors and I'm able to package and install on my router (TP-Link TL-MR3020).

To be sure it's working correctly, I transferred setup.py to my router and ran the self-test. All the tests passed except for the 9 RIPEMD-160 hash tests. The library function(s) seem to return normally, but the returned hash is incorrect, e.g.:

FAIL: runTest (Crypto.SelfTest.Hash.common.HashSelfTest)
RIPEMD #1: '' (empty string)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/Crypto/SelfTest/Hash/common.py", line 88, in runTest
    self.assertEqual(self.expected, out1)   # h = .new(); h.update(data); h.digest()
AssertionError: '9c1185a5c5e9fc54612808977ee8f548b2258d31' != '7c7c0f550ddb9e5ebf157869ea147e65cb89bb0e'

I'm unsure how to proceed at this point; my searches on Google haven't returned any relevant results. What area/library/etc should I investigate/debug to fix this? Any help would be appreciated.

Thanks!
Jeff

Thanks to Legrandin on the PyCrypto mailing list, I was able to fix this by patching setup.py to use the endianness of the target system.

I've opened a pull request for the python-crypto package at GitHub if anyone is interested: https://github.com/openwrt/packages/pull/1900
