Read user input, Encrypt the data and write to file
Hi,
can some one help me how to encrypt and decrypt a file.
AIM: reade user input, encrypt it and save it to file.
while decryption read the encrypted file decrypt it and save the output in some variable.
Example: consider we have Credentials.txt file with content username: password
when user run a script, it should ask them to enter username and password in format of "username: password".
when user enters them, it should get encrypted and save to credentials.txt file.
while decryption, read the credentials.txt file decrypt it, then split the content before and after the delimiter : and store them into two different variable like username should get stored in $usr and password should store in $passwd. i will use this variable in further script
im trying from very long time to hw to achive this. i will be very thank full if some one help me....

partimaged-passwd(8) Partition Image Server Configuration partimaged-passwd(8) NAME
partimaged-passwd - Manage partimaged user accounts SYNTAX
partimaged-passwd [-Dhl] username password partimaged-passwd [-Dhl] username DESCRIPTION
partimaged can either authenticate against local user accounts (This needs access to /etc/shadow. As this is a potential security risk this method is not recommended) or its own password database in /etc/partimaged/passwd.db. To simplify the management of the partimaged user database this tool was written. It allows to easily add and remove users or list the users in the database. All users in this database are allowed to access the partimaged server. OPTIONS
-D username Delete the specified user from the password file. -l List users in password file and exit. -h Output help information and exit. FILES
