Comparing Asymmetric Encryption Algorithms

In Part 1 of our crypto blog, I briefly introduced the concept of asymmetric encryption algorithms and the general rule that the longer the key the better. Let’s take a deeper look at that logic here in Part 2. There are many asymmetric encryption algorithms, but lets focus on RSA, which is one of the

Does Key Size Really Matter in Cryptography?

One of the most interesting and useful aspects of the YubiKey NEO and NEO-n is that they can act as a smart card and come pre-loaded with a bunch of interesting applications, such as an implementation of OpenPGP Card. Many end-users like this functionality, but some question the key lengths. It’s an expected cryptographic question

A Crash Course in Cryptography

To better understand asymmetric cryptography, you need knowledge of some basic concepts. For those that are not familiar with public-key cryptography, I will provide here a brief, stripped-down introduction to the topic. In asymmetric or public-key encryption there are two main players: the encryption algorithm itself (RSA, ECC, ElGamal, …) and a cryptographic key pair (there

We Love Third-Party Validation!

It’s always rewarding when you see third-party validation of your company’s product, and that is why today started off so well. In separate articles published today, Yubico’s YubiKey was highlighted for its tight security and ease of use by authors Don Sambandaraksa at TelecomAsia.net, which is aimed at the telecom market, and Greg Harvey, co-founder

YubiKey’s Hollywood Cameo Trips up Bad Guys

The YubiKey made it into Hollywood’s spotlight last weekend, taking on a plot-turning cameo appearance in the movie Blackhat. (Cue the suspenseful music). When it was all said and done, the YubiKey showed some of the power of two-factor authentication – not in terms of fingering (pun intended) the suspect, but narrowing the field of potential
