crypt and passwords

[david at thekramers.net (David Kramer)]

I once knew the magic incantations for being able to verify a passwd by 
passing the salt from the encrypted password and the unencrypted password to 
crypt() to see if you got a string matching the encrypted password.  I'm 
trying to write a small test program to do this, but I am not getting the 
encrypted string back.

My first guess is this has to do with /etc/shadow passwords now using MD5, but 
according to the crypt man page, it should handle that.

This is Red Hat 7.3.
