Hi Mirni tahnks fo rthe code. in encryption part it is working fine. a small modification, it should not prompt user to enter the key. is there any other way to encrypt the content without giving key and write output to file.
why im asking is while dycrypting it should not ask me to provide key. im going to sdecrypt the credentials.txt.encrypt file with another script. also can you plz give me code for encrypt and decrypt seperately.

encrypt
encrypt(3C) Standard C Library Functions encrypt(3C)
NAME
encrypt - encoding function
SYNOPSIS
#include <crypt.h>
void encrypt(char block[64], int edflag);
Standard conforming
#include <unistd.h>
void encrypt(char block[64], int edflag);
DESCRIPTION
The encrypt() function provides (rather primitive) access to the hashing algorithm employed by the crypt(3C) function. The key generated by
setkey(3C) is used to encrypt the string block with encrypt().
The block argument to encrypt() is an array of length 64 bytes containing only the bytes with numerical value of 0 and 1. The array is mod-
ified in place to a similar array using the key set by setkey(3C). If edflag is 0, the argument is encoded. If edflag is 1, the argument
may be decoded (see the USAGE section below); if the argument is not decoded, errno will be set to ENOSYS.
RETURN VALUES
The encrypt() function returns no value.
ERRORS
The encrypt() function will fail if:
ENOSYS The functionality is not supported on this implementation.
USAGE
In some environments, decoding may not be implemented. This is related to U.S. Government restrictions on encryption and decryption rou-
tines: the DES decryption algorithm cannot be exported outside the U.S.A. Historical practice has been to ship a different version of the
encryption library without the decryption feature in the routines supplied. Thus the exported version of encrypt() does encoding but not
decoding.
Because encrypt() does not return a value, applications wishing to check for errors should set errno to 0, call encrypt(), then test errno
and, if it is non-zero, assume an error has occurred.
