I wrote this to send files to people. It is unique because:
- It runs on any machine with Python, requiring no additional software
- It doesn't need to be base64-encoded
- It evades detection by mail filters
For some binaries, the output is still smaller than the input:
rowlf /tmp$ mbarc /bin/bash > foo rowlf /tmp$ ls -l foo /bin/bash -rwxr-xr-x 1 root root 701680 2007-10-05 08:37 /bin/bash* -rw-r--r-- 1 neale neale 460721 2008-07-15 21:53 foo rowlf /tmp$
If you don't see the point, then you didn't need it in the first place. JP ought to get it.
