Fortify Allows Users to Generate X.509 Certificates in Their Browser

Posted by on June 19, 2018 in Blog | 0 comments

Fortify, an open source application sponsored by Certificate Authorities through the CA Security Council, is now available for Windows and Mac. The Fortify app, which is free for all users, connects a user’s web browsers to smart cards, security tokens, and certificates on a user’s local machine. This can allow users to generate X.509 certificates in their browser, replacing the need for the deprecated functionality. Certificate Generation In The Browser The Web Cryptography API, also known as Web Crypto, provides a set of cryptographic capabilities for web browsers through a set of...

How Does the ROCA Attack Work?

Posted by on November 9, 2017 in Blog | 0 comments

On October 17th, a group of Czech researchers announced they had found a way to factor the moduli of many RSA public keys generated by hardware produced by Infineon Technologies AG.  The technical details were presented in a paper at the 2017 Computer and Communications Security conference, hosted by the Association for Computing Machinery on November 2nd. The technique only works against the key pairs produced by Infineon’s library, because it exploits the unique method they use to generate RSA primes.  Key pairs produced by other methods and libraries are unaffected.  However, Infineon’s...
