Password Protection using Term::ReadKey

Hi Friends,

I execute a perl script with password as input but i wish not to print the password when i give the input. Instead when i provide the password it could be shown as "****" instead of original password. I know we can use Term::ReadKey or IO::Prompt for this, but just wanted to know if i need to install them locally. Can i download the package and share it in a shared directory so that i can execute it from any host. I tried this but when i use the shared path in script use lib <shared-directory> doesnt work. Is Term::ReadKey install independent module? If not is there any other way of doing the same? Thanks in advance.

RADCRYPT(8)						      System Manager's Manual						       RADCRYPT(8)

NAME
radcrypt - generate password hash for use with radius, or validates a password hash SYNOPSIS
radcrypt [-d|--des] [-m|--md5] [-c|--check] plaintext_password [hashed_password] DESCRIPTION
radcrypt generates a hashed digest of a plaintext password, or can validate if a password hash matches a plaintext password. DES and MD5 hashes are currently supported. When generating a password hash a random salt is generated and applied. A hashed password can be validated by specifying -c or --check and passing hashed_password after plaintext_password on the command line. In this case hashed_password will be checked to see if it matches plaintext_password. If so "Password OK" will be printed and the exit sta- tus will be 1, otherwise "Password BAD" will be printed and exit status will be 0 (Note this is the opposite of a normal successful shell status). OPTIONS
-d --des Use a DES (Data Encryption Standard) hash (default). Ignored if performing a password check. -m --md5 Use a MD5 (Message Digest 5) hash. Ignored if performing a password check. -c --check Perform a validation check on a password hash to verify if it matches the plantext password. EXAMPLES
$ radcrypt foobar HaX0xn7Qy650Q $ radcrypt -c foobar HaX0xn7Qy650Q Password OK SEE ALSO
