bash_password_manager

Using a UNIX terminal, the following scripts will allow you to manage a passwords encrypted text file by 2 main functions: adding new passwords(password_manager_encrypt) and getting existent passwords (password_manager_decrypt) and copying them to the clipboard. Both operations are described in detail below.

password_manager_decrypt

password_manager_decrypt does the following:

Given an entered name of an account, searches for it in the passwords file (in fact, a previously and temporary decrypted file of the provided encrypted passwords file):

• If the entered account name is found in the passwords file: Shows the username for the desired account and pastes its password to the clipboard.

• If the entered account name is not found in the passwords file, simply shows a message saying the username and password for the requested account have not been found.

password_manager_encrypt

password_manager_encrypt does the following:

Given an account's name (for instance, "gmail"), its username and its password, decrypts the old encrypted passwords file (if existent, otherwise it creates it).

Adds at the end of the resultant decrypted file the given account's details (name, username and password).

Then it encrypts the new decrypted file (which, again, contains new account's details).

usage

password_manager_decrypt: ./password_manager_decrypt.sh [accountName]

password_manager_encrypt: ./password_manager_encrypt.sh [accountName] [userName] [password]

to consider

1. Both scripts delete the decrypted passwords file as soon as it's not needed anymore, for security purposes.

2. Each line of the decrypted/plain passwords file must have the following FORMAT: "accountName=userName=password", each field must be separated by the "=" token.

3. To encrypt the passwords text file it uses "openssl aes-256-cbc -salt -in /Users/yourUser/psw_decripted.txt >> /Users/yourUser/psw_encripted.txt" (Replace the PATHS as you wish, as well as the encryption algorithm), set your own encryption password which will be requested to decrypt when you run the script.

4. A future operation to add to the script could be modifying existing usernames and/or passwords.
