[cs631apue] Question about the key

[tparisi]

Hi,
I was wondering what we should do with a key that is entered that is 
less than 128 bits.  My thought is that it should not be used as it is 
not large enough but something could be appended to the end to make it 
128 bits.  Since this is not specified in the man page, I do not know 
what to do.

Also, I was wondering if we could use the example code from the man 
page in our homework since our homework is going to end up being very 
similar to the man page example.
Thanks,
Tom
