How to encrypt your email

Most email messages you send travel vast distances over many networks, secure and insecure, monitored and unmonitored, passing through and making copies of themselves on servers all over the Internet. In short, pretty much anyone with access to any of those servers – or sniffing packets anywhere along the way – can read your email messages sent in plain text.

Now more than ever, you might want to encrypt your email to protect it from prying eyes. Not only do we have government snoops mining vast amounts of data on the net and an ever-increasing number of companies monitoring their employees’ email, but phishing and other email scams increase by the day.

PGP_Icon.pngPGP (Pretty Good Privacy) software won’t protect you against the focused attention of a major government, but it will stop efforts to harvest credit card numbers and information that can be used to commit identity theft. Email encryption is easy, free and offers strong protection against prying eyes.

How PGP email encryption works

Consider this scenario.

Sam wants to send Jane a secret email love letter that he doesn’t want Joe, Jane’s jealous downstairs neighbor who piggybacks her wifi, to see. Jane uses PGP, which means she has a PUBLIC key (which is basically a bunch of letters and numbers) which she’s published on her web site for anyone who wants to send her encrypted email messages to use. Jane’s also got a PRIVATE key which no one else – including Joe the Jealous Wifi Piggybacker – has.

So Sam looks up Jane’s public key. He composes his ardent profession of love, encrypts it with that public key, and sends Jane his message. In sending, copies of that message are made on Sam’s email server and Jane’s email server – but that message looks like a bunch of garbled nonsense. Joe the Jealous Wifi Piggybacker shakes his fist in frustration when he sniffs Jane’s email for any hint of a chance between them. He can’t read Sam’s missive.

However, when Jane receives the message in Thunderbird, her private key decrypts it. When it does, she can read all about Sam’s true feelings in (pretty good) privacy.

You too can get PGP set up in a few simple steps.

Configure PGP in Thunderbird

The easiest tool to use is Mozilla’s email program, Thunderbird with the Enigmail extension. (Be sure to click “Save Link As…” and download the extension to your computer; otherwise Firefox will try to install it.) You’ll also need to download a the free GNUPGP software for Windows.

Here’s how to put it all together.

Run the GPGP installer. It should put GNUPGP under your Program Files directory.

Once you’ve downloaded Enigmail, in Thunderbird open Tools -> Options -> Extensions -> Install New Extension, and then choose the Enigmail extension file.

When you’ve restarted Thunderbird with Enigmail installed, you will see an OpenPGP menu item. Open it and go to Preferences. There you’ll find a dialog to point to your GnuPGP binary. Click Browse. On my machine, GPG was installed under Program FilesGNUGnuPGgpg.exe.

Now you’ll need to generate your public/private key pair. From the OpenPGP menu item, choose Key Management. From the Generate menu, choose New Key Pair. Choose the email address you want to create a key for, and set a passphrase. Hit the “Generate Key” button, and relax – it can take a few minutes.

When it’s done, you have the chance to generate a “revocation certificate.” This certificate can invalidate your public key just in case your private key is ever compromised. Go ahead and get your revocation certificate and save it.

Once that’s done, you’re all set to send encrypted mail. To find someone’s PGP key, from the OpenPGP menu, choose Key Management. From the Keyserver menu, choose Search. Search for another PGP user by name or email address and add his or her key to your key manager. Once it’s in there you will be able to encrypt mail to that person.

gnuPGPKey.bmpThen, compose your message as usual. Encrypt it by clicking the little key down on the lower right of your compose window. You can also cryptographically sign your message to prove it’s you; that’s the little pencil. Both of these buttons will turn green to show that they’re active.

Easy as pie!

In order to ensure that operators are able to carry out their day to day tasks without the need for constant assistance from other staff, providing appropriate lifting equipment for anyone who needs to be able to lift material of heavy objects in order to get access to them and move them around is necessary. Material handling cranes that are designed to be mounted above a working area to lift objects onto and off workbenches are considered to be vital equipment.

There are various different designs of material handling crane available to carry out different functions. The different models can be mounted in different ways, and can be either fixed or completely portable. Wall mounted and floor mounted material handling cranes fulfill different purposes, and work in slightly different ways, and ensuring that you invest in the right equipment for your workplace can provide huge long term cost benefits in terms of improved productivity.

The most popular style of material handling crane from the point of view of making it a simple matter to load material onto a workbench is a portable gantry crane. These stable units are designed to be wide enough to straddle a workbench and raise the object being lifted high enough to be placed comfortably onto the bench without damaging it. These cranes are designed to be able to lift weights up to 2000 pounds, and feature a wide chassis with hardwearing casters to make moving it around easy. Depending on the exact specification of the crane, the top bar of the crane can be up to 90 inches above the ground, ensuring that even the largest object can be comfortably put into the right place.

The much larger and more powerful steel gantry crane is able to lift much heavier weights up to 8,000 pounds and coming complete with 4 heavy weight and fully adjustable casters, the steel gantry crane is intended to be used in a heavy industrial environment to allow operators to enjoy much easier access to materials throughout the workplace.

An alternative to the portable gantry for lifting heavy objects is the cantilever jib. Rather than being designed around a concept that straddles the work bench, the cantilever jib is a materials handling crane has a single post that is weighted for stability. The crane offers benefits in terms of the flexibility with which objects can be moved from one place to another, and also allows for rotation of materials, allowing for a greater degree of manipulation.

All of the materials handling cranes are built to the highest standards using top quality steel or aluminum, and come complete. They are powder coated in order to ensure a longer life, and thanks to the simple operating methods of the lifting gear, staff will be able to begin to use the equipment almost immediately.

Regardless of the exact system that you opt to install in your workplace, you will find that the material handling cranes are both efficient and hardwearing and will serve you well in the long term. Purchasing one of these fine lifting systems should be seen as an investment in, rather than a cost to, your business.
