FWIW. The patent on MDC2 has expired.

Please note, for MCD-2 and RC4:

Note also that usually it's not enough just to say "no patents"; do
you care about technology that is patented, but one for which the
patent is available in the public domain (e.g., such as was the case
with DES), or code licensed under a certain license (such as the case
with the RCU patent in the kernel), or if the code is used to
implement a certain protocol (as is the case with various patent
pledges out there)? It's rare that someone really means "no patents
whatsoever."
