l0ck3r

Automated encryption utilities and installation

I wanted to write a script to automate some encryption related operations but i may have gone a little overboard. Regardless the tool automates OpenSSL, has a feature to securely backup data in an encrypted archive and shred the original files. It also automates the installation of the pwgen, shred, OpenSSL, 7z and encryptcli utilities as well as the installation of VeraCrypt and Encryptpad.

Quick Usage

Using L0ck3r is fairly straightforward.

Starting the script with -D or --dep-install will install L0ck3r's dependencies. After which the script is ready for use.

Choose Encryption or Decryption respectively to start your crypto operations.

When supplying input files please enter full paths. With some exceptions; Running the script from the home directory to encrypt files in the home directory entering the target file should be done like so when prompted:

Path: ./file_to_encrypt.txt

After you have made your choice you will be asked for the algorithm you wish to use and the password. The script does the rest.

Note

There may be some bugs, this is a beta. I wasn't originally going to put this on Github, but i figured it might be useful to others.

If you're having issues, just running the installer operations will set you up nicely with a lot of useful stuff in and of itself. For your convenience, i pulled the installation function out and pasted it here, if you're interested.
