Does anybody know of an existing C extension that interfaces with ruby 
code for the sole purpose of hiding important encryption info, such as 
the SALT?  When users write encrypt/decrypt methods it would be nice to 
call a C interface to obtain the salt/iv.  This way general users would 
have a harder chance of cracking the encryption.  Using this method 
wouldn't about the only way to obtain the sensitive data by reading each 
RAM address and try to grab the value while that Ruby method executes 
while it's calling the C extension.

If one doesn't exists is this something other users would take advantage 
of if one was written?

Look forward to all the suggestions!
