I've done something similar in a personal project. I'll post some code  
today that can replace

char * shahash(char *);

in sha.c

In OpenSSL's libcrypto, all hash functions are handled in the same  
manner. To switch which one is used is typically just a matter of  
changing a function pointer to the underlying implementation. Given  
that, I propose a single function to calculate a message digest on  
arbitrary data. The sha and md5 functions could be simple wrappers  
around the base function.
