I was in the RAF from Nov 1993 to Dec 2000. These pictures are from my trade training days at RAF Locking near Weston-Super-Mare, 9 Feb 1994 - 1 Aug 1994. I was on course TCO 114.
At RAF Locking I was trained as a Telecommunications Operator (TCO). A TCO mainly worked in Communication Centres or Signals Unit's, operating a variety of telegraphic, cryptographic, radio, and Morse equipment. TCO's were also trained as Telephonists where they worked in station telephone exchanges. TCO's could also serve in a field comms role at Tactical Communications Wing (TCW) RAF Brize Norton, a role in which I served in early 1998.
I later returned to RAF Locking in 1997 to undertake my Morse course (3 Mar 1997 - 10 Jun 1997); I was on QMC 41.
The operational units I served at were:
RAF Waddington
TCW, RAF Brize Norton (detached to Bahrain)
RAF Coningsby

(Wik-Exc: "Shor's algorithm, named after math. Peter Shor, is a quantum algorithm (.. runs on a quantum computer) for integer factorization discovered in 1994. Informally it solves the following problem: Given an integer N, find its prime factors."

I think if it had four rotors then it was owned by the Kriegsmarine, which was the U-boat people. The other machines only had three rotors, which probably explains why the code was so hard to break for the U-boats and so many boats were sunk in the Atlantic. Eventually some of these were captured along with code books and used to help break the codes back at Bletchley.
If you must, you can watch a travesty of a film called U-571 which takes the real Operation Primrose and claims Jon Bon Jovi did it all himself. Also, see U-559 photo. But Enigma with Kate Winslet is probably a better choice if you want a more factually accurate bit of Enigma porn (aside from that whole Official Secrets Act thing).

It's impossible to reverse engineer a SHA-256 hash. Enter your guesses into a SHA-256 hash generator and see if your hash matches this artwork.
Bitcoin mining uses the SHA-256 as the Proof of work algorithm. Each bitcoin block is identified by a unique SHA-256 hash.
This artwork is identified by its unique hash, which is created from its original identity. Decode the hash, and you'll decode the original title.
The Engima machine is an iconic device in the history of cryptography. The breaking of the Enigma ciphers by cryptographers working at Bletchley Park - "Station X", as it was called - is one of the most remarkable stories of World War II. This and other efforts by the staff of Station X shortened the war by an estimated two years, saving a great many lives.

The Electronic Associates, Inc. Pace TR-10 general-purpose analog computer, introduced in 1959, used electrical components and circuits to provide solutions for mathematical equations. A mathematician, scientist, or engineer plugged modules into the TR-10, connected sections of the TR-10 with cables, and adjusted the parameter knobs at the top to represent a mathematical equation and its input parameters. The resulting voltages provided the solution to the equation. The TR-10 was capable of solving 10th order differential equations.
To provide a sense of life as an engineer before the digital age, here is an excerpt from the TR-10 manual:
------------------------------
New EAI computer puts the advantage of analog computation right at your desk. Accurate up to 0.1%, it is capable of performing the mathematical operations of summation, integration, sign changing, multiplication, division, and function generation; those operations required in the solution of most of your routine engineering problems. Differential equations, basic to most engineering problems, can now be solved with surprising rapidity. Even if you have never seen a computer before, you can learn to operate the TR-10 as easily as you learned to use a slide rule.
You simply turn a knob to feed in design parameters. The computer provides an instant-by-instant dynamic picture of the effect of each change. You can study relationships of heat, pressure, flow, vibration, torque or any other variable. And you can visually compare one with the other. This new insight into the behavior of differential equations helps you to arrive at solutions faster … easier.
Because of its unique portability, this compact computer can become your personal tool. Carried right to your desk, it can be used to solve your day-to-day problems, saving you time and eliminating the drudgery of repetitive hand calculations. By allowing you to spend more of your time on creative engineering, it can enhance your value as an engineer.

An observation from someone who is not an expert in cryptography: Cryptography is about converting order (a written or spoken message) to disorder (an encrypted communication with no clear patterns) and vice versa. Thus, I find it interesting that a number of tools for cryptography—especially prior to the digital age—have a physical order or pattern.

The QDC label marked the 1930 introduction of a cryptographic system of model designation that WACO used to identify its various models. The first letter identified the engine-type, the second the wing style, and the third the fuselage design. Each letter also indicated if the aircraft was built before or after 1930—a very confusing conglomeration of letters that required a scorecard to decipher.
The keys of an enigma machine. Forgot to check where they aquired this: wonder if it was one of the captured ones from Bletchley?

Yesterday was Christmas decoration party at the post-graduate labs. I've got absolutely no talent for such things. Yvette helped me to decorate the crypto lab.

Probably the first programmable computer in the world!
The first machine designed to break the Lorenz was built at the Post Office research department at Dollis Hill and called ‘Heath Robinson’ after the cartoonist designer of fantastic machines. Although Heath Robinson worked well enough to show that Max Newman’s concepts were correct, it was slow and unreliable.
