I've had a look at why SSLeay's blowfish in cbc mode does not
interoperate
with the version in SSH, and it is because while blowfish is internally
a big-endian algorithm, SSH's cbc code is loading the data
little-endian.

It is relatively simple to add code to do things the broken way if
required...
any interest?

PS I actually did the same stuff up when I first implemented cbc mode
for
   idea.  It is one reason why I feel any new cipher should supply test
   vectors that are 'byte streams' rather than input words (be they 32
bit
   for blowfish, or 16 bit for IDEA).
