I am writing a UNIX program to verify a user's UNIX user name and password. UNIX includes a structure called passwd that allows programmers to verify fields in the passwd file. Comparing and verifying the user inputted/supplied name can be accomplished using this structure; however, the users inputted/supplied password can not, since it must be encrypted before it can be used. Is there a function that encrypts the user's inputted password? Th objective is to compare it against the field in the passwd file.<br />

Verifying a user's password

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
