As a system administrator, or any other occupation that you have to deal with sensitive information, it is often recommended that you encrypt the sensitive information in case it is stolen or found.

Personally, for the encryption of files I use a program commonly found on *Nix systems called "CCrypt". CCrypt uses AES-256 encryption which is very strong.

Here's an example:
I have a master password file, and say that the contents are such:

After install ccrypt I type:

Then, when I view the encrypted file:

Don't think anyone is going to be view this!


Similarly, you can decrypt with "ccrypt -d" and view/cat with "ccrypt -c"
