SplashID: Unable to Sync Because iPhone Shows No Desktop found…

I decided to finally make the jump to some sort of information manager after a talk I had with someone at work today. When working for so many companies , managing so many devices, and being a member of so many web communities it is almost impossible to remember login information, IP information, and random other notes about every installation, web site, etc. I started looking for a solution where I could at least store devices, I could access this information from anywhere (at least on my Touch), and it was secure. I was pleasantly surprised by SplashID which will allow you to store all sorts of information in all sorts of ways. The best part is that when it boils down to it this information is going to be more secure in a solution like SplashID, which uses encryption that tops banks, versus being spread through out various notepads, documents, emails, and other places on numerous computers and possibly even on paper.

DDWRT – What do the PPTP Settings for MPPE no40 and no56 Mean?

MPPE stands for Microsoft Point to Point Encryption. MPPE is used to encrypt data traveling over a PPTP, or Point to Point Tunneling Protocol, connection.

When setting up a PPTP connection using DD-WRT firmware on your router there is a blank field to configure MPPE Encryption options in the VPN/PPTP setup. By default the text “mppe required” is typed into this field. You can add a couple other options which include no40, no56, and stateful or stateless. Descriptions of these options are listed below.

Send PGP Encrypted Messages with Gmail

The easiest way to send encrypted email with Gmail that I have found is to do so with Firefox and the FireGPG plugin. You can either encrypt the message before typing it into Gmail or you can type the message and then highlight the text and run the FireGPG plugin to encrypt it. Below are a few simple steps that should help encrypt email you are sending through Gmail to someone who has a PGP key.

NOTE:The below steps are if the FireGPG buttons are not showing in Gmail and is a temporary fix until FireGPG is updated and the entire message can be encrypted. I will update this with a link to the new article/howto once FireGPG is updated.

Trillian Secure ICQ And AIM Messages With Off-The-Record Messaging

One thing most people do not realize is the fact that sending Instant Messages over the Internet is not secure. Every time you speak with someone you risk the chance of someone listening in on those conversations. Especially now a days with so many wireless networks hackers can easily join networks and grab all of the data off those networks. There is any easy way to encrypt your AOL Instant Messenger and ICQ by using a plugin for Trillian. You can also encrypt either one if not using Trillian which is briefly discussed below. Follow these steps to install Off-The-Record Proxy and configure Trillian to use it to encrypt your messages to other users who also have the software installed. The below steps were performed on a laptop running Windows XP Professional 32-Bit.
