Most solutions that encrypt files require the installation of encryption software which has to be started again if you want to decrypt the encrypted files. A quick and easy way to encrypt text files would be to use the free Steganos Locknote program which encrypts text files using the 256 AES algorithm.
I'm going to show you how to create a secure usb data safe that can be used to store sensitive data. Secure means it is encrypted and will only be encrypted if you need the data that is saved on the stick. This method is also working with other removable media such as zip drives and hard disks.
Would you prefer that important data like information about yourself, account numbers, personal documents and the like are accessible all the time from everyone who has access to your computer or that this data is only available to someone with special access ? I would like to give details on an easy way to store your data safely on your computer without wasting lots of time. It may be safer keeping the data in a safe in your appartement but this is not really practicable.
Freenigma offers a free firefox extension that adds cryptography functionality to Yahoo, Gmail and MSN. The team says it is working on adding other emails services, as of now, only the three services mentioned are supported. You have to signup at their website to recieve an invitation before you will be able to download the extension. They state that it could take a few hours the most before you recieve the invitation. Mine arrived about ten minutes after I completed it.
You might know that I´am using True Crypt for some months now to encrypt and decrypt my entire removable hard disk that has 300 Gb capacity. All happens in realtime and I can´t see and witness any slowdowns so far. I´am able to download content to the drive with 14.2 Mbps and its working like every other hard disk. Yesterday a new True Crypt version was released and it has some amazing new features, let us take a look at some of them:
Most people think it takes lots of work to encrypt files. The freeware click crypt 2.6 allows to encrypt and decrypt files with just one click. It´s unfortunatly only available in german but that does not matter a lot because the interface is simple and easy. Click on Download Sofort ausführbares Setup which starts the download. After that install the software on your system and start it. This opens a configuration window which is named Verschlüsslungsmethoden. You select the encryption algorithm that you want to use, you have three options, those are: MD2 (128bit), MD5 (128bit) and SHA (160 bit).
Only a few days ago I wrote a first small article about true crypt and recommended it. Back then I bought a usb 2.0 hard drive with 300 GB capacity and encrypted its entire partition with true crypt. This was done to test the programs functionality but also to see if it would slow down my main computer (athlon 64 3000+, 1 gb ram).
To my great suprise it did not slow down the pc and I decided to expand the encryption to cover all my hard drives. Let me tell you why and how i did this and why you should also be considering this.
I thought about encrypting my hard disks, or at least part of them that contain personal data, for at least one year. I never did it because I thought it would be a lot of work involved. I had to find a good program, one that would offer good encryption algorithms, would be free and easy to use.
