##### SUMMARY
Customer request: When typing the string to encrypt, it shows up as plain text. Since the string is being encrypted, it's safe to assume that it's sensitive (e.g. passwords) and should therefore be hidden. At the very least, maybe this could be a command line option. If it is hidden, I'd prefer to be forced to enter it twice to avoid mismatch. To mitigate this issue, I am currently using "stty -echo", but that shouldn't be necessary.
