[1] see if your server has expect or autoexpect. This is a interactive utility that will allow you to issue the commands to telnet to each server and collect the data.
[2] There are some password encryption utilities you can get to encrypt the passwords. Ultimately your script will have to unencrypt them to use them to login to the remove systems, which negates having them encrypted, because you have just provided all the information needed to decrypt them. If the switches support SSH setup encryption keys so your script will not have to provide a password.

crypt::des_ede3
Crypt::DES_EDE3(3pm) User Contributed Perl Documentation Crypt::DES_EDE3(3pm)
NAME
Crypt::DES_EDE3 - Triple-DES EDE encryption/decryption
SYNOPSIS
use Crypt::DES_EDE3;
my $ede3 = Crypt::DES_EDE3->new($key);
$ede3->encrypt($block);
DESCRIPTION
Crypt::DES_EDE3 implements DES-EDE3 encryption. This is triple-DES encryption where an encrypt operation is encrypt-decrypt-encrypt, and
decrypt is decrypt-encrypt-decrypt. This implementation uses Crypt::DES to do its dirty DES work, and simply provides a wrapper around that
module: setting up the individual DES ciphers, initializing the keys, and performing the encryption/decryption steps.
DES-EDE3 encryption requires a key size of 24 bytes.
You're probably best off not using this module directly, as the encrypt and decrypt methods expect 8-octet blocks. You might want to use
the module in conjunction with Crypt::CBC, for example. This would be DES-EDE3-CBC, or triple-DES in outer CBC mode.
USAGE
$ede3 = Crypt::DES_EDE3->new($key)
Creates a new Crypt::DES_EDE3 object (really, a collection of three DES ciphers), and initializes each cipher with part of $key, which
should be at least 24 bytes. If it's longer than 24 bytes, the extra bytes will be ignored.
Returns the new object.
$ede3->encrypt($block)
Encrypts an 8-byte block of data $block using the three DES ciphers in an encrypt-decrypt-encrypt operation.
Returns the encrypted block.
$ede3->decrypt($block)
Decrypts an 8-byte block of data $block using the three DES ciphers in a decrypt-encrypt-decrypt operation.
Returns the decrypted block.
$ede3->blocksize
Returns the block size(8).
$ede3->keysize
Returns the key size(24).
