Hi,
I'm trying to implement a new stream cipher algorithm in OpenSSL
(stream cipher Rabbit, see RFC 4503 -- in my previous email, there was
a mistake, I tiped 4509, really sorry). This new algorithm will be
used for testing purpose. I've written and added new lines in OpenSSL
0.9.8c. So far this algorithm works for encryption/decryption only
(not yet for SSL) -- with the argument 'openssl -enc -rabbit -in ...
-out ...'.
At present, I'm working on the code for the cipher test ('rabbittest'
- I adopted the codes from rc4test.c). The code has already been
working on encryption test (test 0...3). Unfortunately, it shows
errors when it tests the cipher length test.
D:\Projects\Openssl-0.9.8c\out32dll>rabbittest
test 0 ok
test 1 ok
test 2 ok
test 3 ok
test end processing .
error in Rabbit length processing
output: 8e 65
expect: 8e 00
error in Rabbit length processing
output: 8e 65 b4
expect: 8e 65 00
error in Rabbit length processing
output: 8e 65 b4 ff
expect: 8e 65 b4 00
error in Rabbit length processing
output: 8e 65 b4 ff 14
expect: 8e 65 b4 ff 00
...
...
I've checked the code many times, but I couldn't find the bug. Below
is the 'rabbittest' codes :

I would thank so much if you can help me to know what's the problem
with the codes and how I can solve it.
Best regards,
