  • My Work Day Reflects YubiKey’s FlexibilityI work as a developer at Yubico. Like a lot of developers these days I’m empowered to not only develop software, but to publish it and configure the servers it runs on. This means that I have access to many systems, to which I authenticate using different keys, requiring the flexibility of a YubiKey. The […]Read moreauthenticationFIDO U2F security keyU2FWorks with YubiKey
  • Yubico LogoThe Big Debate, 2048 vs. 4096, Yubico’s PositionIn Part 2, we got a better understanding of what an algorithm like RSA does and what the length of a key entails. Now, in Part 3, we can talk about the elephant in the room. Are 2048-bit keys useless? And are your documents completely insecure if you are using them? What are the pros […]Read moreabout Yubico
  • Comparing Asymmetric Encryption AlgorithmsIn 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 […]Read moresecure encryption
  • 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 […]Read morecryptographyOpenPGPYubiKey NEO
  • A Crash Course in CryptographyTo 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 […]Read morecryptographydevelopersFIDO U2F security key
  • Yubico Meets President ObamaLast Friday I biked to Stanford to discuss online identity protection with the President of the United States. President Obama is a man passionate about the Internet and dedicated to helping secure it. After our short one-on-one conversation about Yubico solutions, he took the stage at the Stanford Memorial Auditorium. In front of him he had […]Read moreabout Yubicogovernment
  • 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 […]Read moreOpenPGPYubiKey
  • The Key and the PrincessAfter Silicon Valley, Sweden is considered one of the world’s more interesting tech innovation hubs, giving birth to global brands such as Skype, MySQL, Spotify, King – and the rising Yubico! The growing and fruitful cross-pollenization between Silicon Valley and Sweden is the reason Victoria, Crown Princess of Sweden, and her husband, Prince Daniel, this […]Read moreabout Yubico
  • YubiKey’s Hollywood Cameo Trips up Bad GuysThe 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 […]Read moreabout Yubico
  • FIDO U2F Ecosystem Coming AliveUpdate: New entries added to Enterprise Software list; new section, Governments, added; April 13, 2016 FIDO U2F (Universal 2nd Factor) is, as the name implies, a universal protocol that supports a wide range of modalities and use cases. Many people forget this fact given the current popularity of the USB form factor. But evidence is mounting including biometric, software, […]Read moreFIDO AllianceU2FWorks with YubiKey
