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.

Email Encryption Opt Out Now Available for Outlook and Other Email Programs

Friday, December 7th, 2012

A few weeks ago, we introduced the option for users in security-enabled accounts (such as users subject to HIPAA compliance requirements) to determine for themselves which messages need to be encrypted and which do not.  See: HIPAA Compliant Email – You Decide Which Messages Need Encryption

The  “SecureLine Opt Out” feature was then only available to users of our web-based email interface.  Now, the “SecureLine Opt Out” feature is also available to:

  • Premium Mobile Sync users on mobile devices
  • Customers using SMTP from mobile devices
  • Customers using SMTP from most email programs (e.g. Outlook, Thunderbird, Mac Mail, etc.)
We have also enhanced Opt Out to enable administrators to have more control over who can and cannot opt out of SecureLine email encryption.

How to Open and Read .eml Email Files

Wednesday, August 22nd, 2012

Many email programs and services allow downloading and/or saving email messages in a format called “.eml”.  This format is very simple and very standard.  These are plain text files that hold one email message per file and which contain the full message headers and full MIME-encoded message content.

LuxSci allows saving email messages from WebMail and from the SecureLine Escrow portal as eml files for offline usage, and the importing of eml files directly into your email folders.

While .eml is a widely used standard, old versions of Microsoft Outlook (before v2010) do not support it and that leaves many people wondering what to do with these files.

Here we explain how to open and view .eml-encoded message files on your computer.

LuxSci has released several significant enhancements to its email and WebAides collaboration tools services that enable users to use “tags” more extensively to manage, categorize, and sort through their information.

For a long time, LuxSci has provided users with the ability to use tags to label and color code email messages, address books entries, documents, etc.  For details on LuxSci’s tag usage in general, see:

Tags at LuxSci have been enhanced with the following features.

How to Install S/MIME (and PGP) Encryption Certificates into Major Email Clients

Wednesday, May 27th, 2009

We at LuxSci are always being asked questions about various email programs and their usage.  With HIPAA compliance becoming more and more important, we get a lot of inquiries regarding secure email. One of the most frequently asked questions is how to install S/MIME security certificates in various email programs that our servers support. Sometimes finding instructions on installing security certificates in various email clients is difficult, even with the help of search engines. To make your search easier, we have complied instructions for several of the the major email clients:

  • S/MIME for Outlook 2003
  • S/MIME for Outlook 2007
  • S/MIME for Mail.app
  • S/MIME for Entourage
  • S/MIME for Thunderbird
  • PGP for Thunderbird via the Enigmail Add-on.
