Runtime Switches

We want to develop FCrypt to be able to take a series of command line inputs to allow us to decrypt a message, use password-based encryption (pbe) or to display time information for a cipher operation. With that in mind, the following flags are defined appropriately.

static int dflag = 0; 
/* 1 - decrypt */static int tflag = 0; 
/* 1 - time */static int pflag = 0; 
/* 1 - use pbe */ 

Next, see Encrypt Functions.
