RSA Algorithm The RSA algorithm is named after Ron Rivest, Adi Shamir and Len Adleman, who invented it in 1977 [RIVE78]. The basic technique was first discovered in 1973 by Clifford Cocks [COCK73] of CESG (part of the British GCHQ) but this was a secret until 1997. The patent taken out by RSA Labs has expired. The RSA cryptosystem is the most widely-used public key cryptography algorithm in the world. It can be used to encrypt a message without the need to exchange a secret key separately.
Insight & Intelligence™:Best Science Apps: December Picks Trendy Chem ★★★ Platform: iPad/iPhone/Android Cost: Free + Sleek design, good synthesis of information in build mode – Some exercises get a bit redundant You might say that the Trendy Chem app is doubly trendy. First, its sleek, high-tech-looking design is sure to earn "cool" points from chemistry students; second, this app emphasizes teaching students about chemical trends of the periodic table. Through a number of exercises, the app quizzes students on subatomic particles (finding the number of electrons, protons, or neutrons of an element, given the atomic and mass numbers), periodic families (alkali metals, halogens, etc.), and periodic trends (atomic radius, electronegativity, electron affinity, and ionization energy). There is also a neat build mode that has students synthesize information and build elements according to particular requirements (e.g. build a transition metal that has an atomic radius larger than lithium).

It wraps a highly optimized C implementation of many popular encryption algorithms with a Python interface. PyCrypto can be built from source on Linux, and Windows binaries for various versions of Python 2.x were kindly made available by Michael Foord on this page. My only gripe with PyCrypto is its documentation.
SCISS With Uniview 2.0, we take an unprecedented leap to simplicity. A planetarium equivalent of less blackberry and more smartphone. A step removing all technology barriers, enabling your talented scientists and storytellers to focus on live, interactive presentations. With Uniview 2.0, we are not adding more complexity.

Hash functionsEncryption algorithmsPublic-key algorithms Hash functions A hash function takes a string and produces a fixed-length string based on the input. The output string is called the hash value.
25+ apps that the TED staff swears make their everyday lives easier At our small, fast-moving nonprofit company, everyone does a couple of jobs — and productivity apps help us manage roles that shift between coding, writing/designing and running a full-scale conference twice a year. We asked the TED staff what apps they can’t live without. And beyond the classics—Instagram, Google Maps, Spotify, Uber, Seamless—we found some great apps that might help you too. (A star denotes that the app is free, or at least has a free version.) For random life stuff…
