1cryptcat = netcat + encryption
2
3Cryptcat is the standard netcat enhanced with twofish encryption.
4
5Twofish is courtesy of counterpane, and cryptix. We started with the
6Java version of twofish from cryptix, converted it to C++ (don't ask why),
7and enhanced it by adding CBC mode and the ciphertext stealing technique
8from Applied Cryptography (pg. 196)

10How do you use it?
11
12  Machine A: cryptcat -l -p 1234 < testfile
13  Machine B: cryptcat <machine A IP> 1234
14
15This is identical to the normal netcat options for doing exactly the
16same thing.  However, in this case the data transferred is encrypted.

18Known issues:
19It is known that linux will throw errors like:
20/tmp/ccF9UdJx.o(.text+0x6d0): In function `getportpoop': :
21warning: Using 'getservbyname' in statically linked applications
22requires at runtime the shared libraries from the glibc version
23used for linking /tmp/ccF9UdJx.o(.text+0x61f): In function
24getportpoop': : warning: Using 'getservbyport' in statically
25linked applications requires at runtime the shared libraries from
26the glibc version used for linking
27
28This is due to using -static which either Hobbit or someone else
29insists in the Makefile is The Right Thing(tm). The compiled code
30still seems to run without an issue and according to ldd it is a
31static binary.

34Changes -- been putting these in Changelog file...
35
36Since release alot of people have been submitting changes (many times
37for the same thing).  I've been doing my best to keep up, we are trying
38to get this up on sourceforge, but there seems to be some sort of
39"approval" process that makes it unclear if that will actually happen.
40
41So, if you have submitted something, and its not here, let me know.  If you've
42submitted a change, and its here with someone else's name, that just means
43someone else got the same change in before you.
44
45If you have a change, let me know what name if any to include with
46the change.
