256-bit AES Encryption for SSL and TLS: Maximal Security

Wednesday, February 4th, 2015

SSL and TLS are the workhorses that provide the majority of security in the transmission of data over the Internet today. However, most people do not know that the degree of security and privacy inherent in a “secure” connection of this sort can vary from “almost none” to “really really good … good enough for US government TOP SECRET data”.  The piece which varies and thus provides the variable level of security is the “cipher” or “encryption technique”.  There are a large number of different ciphers — some are very fast and very insecure.  Some are slower and very secure.  Some weak ones (export-grade ciphers) are around from the days when the USA did not permit the export of decent security to other countries.

AES, the Advanced Encryption Standard, is a relatively new encryption technique/cipher that is the successor of DES.  AES was standardized in 2001 after a 5 year review, and is currently one of the most popular algorithms used in symmetric key cryptography (which, for example, is used for the actual data transmission in SSL and TLS).  It is also the “gold standard” encryption technique; many security-conscious organizations actually require that their employees use AES-256 (256-bit AES) for all communications.

This article discusses AES, its role in SSL, which web browsers and email programs support it, how you can make sure that you only use 256-bit AES encryption of all secure communications, and more.

New “Mobile Mode” for PDAs and Smart Phones

Tuesday, September 8th, 2009

LuxSci has offered an “Xpress” WebMail portal for many years.  The portal is fast, simple, and works with most devices because it does not use any JavaScript or cookies, and uses few images.  The Xpress portal is good for security, privacy, and access from legacy devices, as well as over very slow connections.

However, the mobile device landscape is quickly changing.  Starting with the iPhone and its full-featured Safari web browser, to the Android, the Palm Pre, and the availability of browsers like OperaMini on many phones, it is now the case that many “cutting edge” phones actually have fast web browsers that fully support JavaScript, AJAX, CSS, and broadband — all the technologies formerly the purview of the desktop.  Their major drawback, however, is still the very small screen. Many of these browsers work perfectly well with most web sites, including LuxSci’s full-featured WebMail portal; however, it can be problematic and painful to use and navigate sites designed for large displays on these device’s small screens.

Enter LuxSci’s new “Mobile Mode”.  Mobile Mode is a new feature of LuxSci’s regular WebMail interface that is available when it detects that you are accessing it using a mobile device, such as an iPhone.
