Some handy cryptography/networking tools

Here’s a list of some nifty cryptography/networking tools Kiel’s pointed out lately:

  • socat — multipurpose relay; think netcat gone wild—​we used this recently to tunnel UDP DNS queries over ssh
  • cryptcat — netcat with twofish encryption (the Debian package adds a man page)
  • rsyncrypto — partial transfer-friendly encryption (modified CBC for smaller change windows similar to gzip; less secure than regular CBC)

And a pretty unrelated but useful Red Hat Magazine article on the new yum-security plugin.
