You can configure OpenSSL so as not to use RC5 and IDEA by using
./config no-rc5 no-idea
-Until the RSA patent expires, U.S. users may want to use
- ./config no-rc5 no-idea no-rsa
-
-Please note that you will *not* be able to communicate with most of
-the popular web browsers without RSA support.

rumoured to exist. This is not a definitive list.

- For people in the USA, it is possible to compile OpenSSL to use RSA Inc.'s
- public key library, RSAREF, by configuring OpenSSL with the option "rsaref".

Read the documentation in the doc/ directory. It is quite rough, but it
lists the functions, you will probably have to look at the code to work out
how to used them. Look at the example programs.
