A Student's Perspective

  Case file #3 The patient is terrified of heights following a "harrowing experience" in the air. The patient claims to "know something about the missing one." Strong antipsychotics will be prescribed. Excerpt from the patient's diary: It wasn't on the 7th one. The pilot was right. They won't find the missing one. I knew I shouldn't have done what I did, but I had no choice. I hated working the railroads. YOU NEED TO FIND IT!  UP BPZMM AMDMV HMZW The patient appears to be talking to someone. An alternate personality, perhaps. More investigation is needed. Age: 92 (89) Weight: 74 kg Height: 180cm BMI: 23 Current medication: Experimental antipsychotics

 Case File #2 Staff Update:  All patients are now required to write a diary. The patient is hallucinating. He keeps mentioning writing about having "figured it out." I am recommending a strong regimen of Haldol, (10mg per day). This should keep the patient calm and cooperative. Excerpt from the patient's diary: "I've figured it out. I've fgured it out. I've figured it out. I've figured it out. I've figured it out. I've figured it out. I've figured it out. I've figured it out. I've figured it out. I've figured it out. I've figured it out. It's missing. They left the key. It's missing. It's missing." The above entry shows the patient's deteriorating mental status. Weekly psychiatric evaluations will be scheduled to remedy the situation. Age: 71 Weight: 45kg Height: 172cm BMI: 15.2 (Severe) Current medication: Haldol (10mg/day)

Most people have come across cryptography in some way, shape or form. To most people, it's just a way of encrypting a message in such a way that only the intended receiver can decrypt it. In this article, I will be exploring the benefits of public-key cryptography, most notably RSA, as well as explaining the basic concept behind computer cryptography for the uninitiated. Cryptography (intro) So, if this is the first time you've heard of cryptography, this section is meant for you! The basic concept of cryptography is relatively simple: You take a message and, combining it with some type of secret shared between sender and recipient, turn the message into something that cannot be understood without said secret. If you've ever come up with some sort of secret code in your childhood (or early adult life, no judgement here), you've probably done cryptography, even if you didn't know it. The simplest form of symmetric-key cryptography is the Cesar Cipher. The way it work...
