</I>><i> PyCrypto's output doesn't match OpenSSL when decrypting a file in
</I>><i> Blowfish CFB mode. To reproduce this, download and test

</I>><i>
</I>><i>
</I>Both are correct. The fact is that they use different default segment sizes
for CFB:
PyCrypto uses 8 bits, and OpenSSL 64 bits.
With:
bf = Blowfish.new(key = key, mode = Blowfish.MODE_CFB, IV = iv,
segment_size=64)
You will get the same result.
