File encryption tools with MAC address as an encryption key
Hi all,
I'm looking for secure file encryption tools that use MAC address as encryption key. FYI, I'm using Red Hat Enterprise Linux OS.
For example: when A wants to send file to B
A will encrypt the file with B's computer MAC/IP address as an encryption key
This file can only be decrypted on B's computer (the tool detects the MAC address before doing a decryption)
If you know such a tool, please let me know.

My dilemma,
I need to send, deemed confidential, information via e-mail (SMTP). This information is sitting as a file on AIX. Typically I can send this data as a e-mail attachment via what we term a "mail filter" using telnet. I now would like to somehow encrypt the data and send it to a e-mail... (1 Reply)

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).
