cfba9c01bf Alter keygen function to generate keys of different lengths. 2009-09-29 00:53:25 -04:00

76d26ae52d Disable OpenSSL engines when building for Android. 
Apparently the Android developers dumped OpenSSL's support for hardware
acceleration in order to save some memory, so you can't build programs using
engines on Android.

8c585cce39 Include util.h and log.h as relative paths. 
This shouldn't be necessary, but apparently the Android cross-compiler
doesn't respect -I as well as it should.  (-I is supposed to add to the
*front* of the search path.  Android's gcc wrapper apparently likes to add to
the end.  This is broken, but we need to work around it.)

d0c212995a Add a SHA256 implementation for platforms that lack it. 
(This would be everywhere running OpenSSL 0.9.7x and earlier, including
all current Macintosh users.)

The code is based on Tom St Denis's LibTomCrypt implementation,
modified to be way less general and use Tor's existing facilities.  I
picked this one because it was pretty fast and pretty free, and
because Python uses it too.

f57883a39e Add basic support for SHA256. 
This adds an openssl 0.9.8 dependency.  Let's see if anybody cares.

8ebceeb352 Make sure that even in the weird fiddly paths that lead to init_keys, 
crypto_global_init gets called.  Also have it be crypto_global_init
that calls crypto_seed_rng, so we are not dependent on OpenSSL's
RAND_poll in these fiddly cases.

Should fix bug 907.  Bugfix on 0.0.9pre6.  Backport candidate.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version. 
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

oprofile was telling me that a fair bit of our time in openssl was spent in base64_decode, so replace base64_decode with an all-at-once fairly optimized implementation.  For decoding keys and digests, it seems 3-3.5x faster than calling out to openssl.  (Yes, I wrote it from scratch.)
