Briefly describe the Perl's crypt() function.
What will be an ideal response?
The crypt() function is a built-in Perl routine usually used as the UNIX password-encryption function. It is based on the data encryption standard (DES) algorithm, and its variations are intended to discourage the use of hardware implementations of a key search. It takes two parameters: key and salt. Key is the user password, and salt is a two-character string chosen from the set [a-zA-Z0-9./]. The salt string is used to perturb the algorithm in one of 4,096 different ways.
