Hello
I'm writing a program to "lock" my computer while in X-mode (sort of my own version of xlock).
I've written the basic stuff.. but now I need encrypt the entered password, and compare it to the encrypted password in the /etc/shadow-file..
I looked in the man-pages for 'des', but I'm a little confused..
There are lots of function there, that generate keys, and encrypt data in different ways..
Which one should I use for my purpose?

You will need to use the crypt(3C) routine.
Thanks 
I want to disable ctrl + alt + del while running the program.. how do I do that?
Is that a signal, just like the interrupt signal?
Just a newbie-question:
What does '3C' mean?
3 chars?
//Maestin
The 3C means that it is section 3C of the manual. On a Sun you would type "man -s3C crypt" to get a man page. With HP-UX, you would type "man 3C crypt".
That cntl + alt + del is a pc concept. I'll have to leave that to someone else.
Just one more question..
When I tried the crypt() function in a sample program, and encrypted my password, it didn't look anything like my password in the /etc/shadow-file..
Do I have to use other functions, to extract the password from the shadow-file?
