Hello Team,

I have the need to encrypt/decrypt a one word string. The encrypted word
will be saved in a file.
Later the word will be picked-up from the file, decrypt it at execution
time, and use it as a UNIX password to perform certain function that
requires authentication.
What Ruby facility is available for this simple function?

Thank you
