If you are talking about the use of these algorithms especially in
OpenSSL, you can just disable them from the OpenSSL build and they will
not be used. Supplicant does not require RC5, IDEA, or MDC2 for anything
and in general, I would just disable them in the OpenSSL build.

I would certainly agree with this part of the comments in OpenSSL ;-).
