I want to decrypt 2 different file types in a folder (ZIP files and GPG files).
Each file type need different decryption syntex.
Hence, the script should identify file type and should act accordingly ignoring file name case i.e. upper or lower case.

I've been using various versions of UNIX and Linux since 1993, and I've never run across one that showed your password as you type it in when you log in, or one that stored passwords in plain text rather than encrypted. I'm writing a script for work for a security audit, and two of the... (5 Replies)

vncpasswd
vncpasswd(1) TightVNC vncpasswd(1)NAME
vncpasswd - set passwords for VNC server
SYNOPSIS
vncpasswd [file]
vncpasswd -t
vncpasswd -f
DESCRIPTION
The vncpasswd utility should be used to create and change passwords for the TightVNC server authentication. Xvnc uses such passwords when
started with the -rfbauth command-line option (or when started from the vncserver script).
vncpasswd allows to enter either one or two passwords. The first password is the primary one, the second password can be used for view-only
authentication. Xvnc will restrict mouse and keyboard input from clients who authenticated with the view-only password. The vncpasswd util-
ity asks interactively if it should set the second password.
The password file name defaults to $HOME/.vnc/passwd unless the -t command-line option was used (see the OPTIONS section below). The
$HOME/.vnc/ directory will be created if it does not exist.
Each password has to be longer than five characters (unless the -f command-line option was used, see its description below). Only the
first eight characters are significant. If the primary password is too short, the program will abort. If the view-only password is too
short, then only the primary password will be saved.
Unless a file name was provided in the command-line explicitly, this utility may perform certain sanity checks to prevent writing a pass-
word file into some hazardous place.
If at least one password was saved successfully, vncpasswd will exit with status code 0. Otherwise the returned status code will be set to
1.
OPTIONS -t Write passwords into /tmp/$USER-vnc/passwd, creating the /tmp/$USER-vnc/ directory if it does not exist, and checking the permis-
sions on that directory (the mode must be 700). This option can help to improve security when your home partition may be shared via
network (e.g. when using NFS).
-f Filter mode. Read plain-text passwords from stdin, write encrypted versions to stdout. One or two passwords (full-control and view-
only) can be supplied in the input stream, newline terminates a password. Note that in the filter mode, short or even empty pass-
words will be silently accepted.
