Encryption.

today, it seems that technology is becoming more and more important in out lives. this is great, but it seems that everything is switching over to online. so what if we don't want to store sensitive data on our computer due to security, yet we have to? well.... we can encrypt the data, so if anyone gets access to our computer, they cant view our data.

another use of encryption is to transmit your data across the internet safely. in this tutorial, we will talk about how to encrypt our personal data, as well as making sure our data is being encrypted safely.



the first thing is to set up truecrypt. truecrypt is an open source program offering some very strong encryption techniques. get it here.

1) open truecrypt and select create volume.


2) choose to create an encrypted file container


3) choose to create a standard volume or a hidden volume.


4) pick where to save your volume, you can rename it and move it later. WARNING: picking a file that already exists will NOT encrypt it, it will erase it.


5)pick your encryption, the strongest would be AES-Twofish-Serpent or Serpent-Twofish-AES.... but even just using one will guarantee that it can not be decrypted.when choosing your hashing algorithm, pick SHA512 or whirlpool, they are both 512 bits compared to ripemd's 160 bit hash.


6)pick your file size. encrypted volumes can not be extended without creating a new volume, so larger is always better.


7)move your mouse around the screen! and then press format.







*8 (if you picked a hidden volume): now add some random files like music to your volume. if someone forces you to tell them your password, this is what they will see.
*9) now create your hidden volume, this is where you will actually keep your files.
NOTE: do not modify or add any files to the outer volume.... if you do, there is a chance it could damage the hidden volumes contents.

now you should be able to mount your file, and it should appear in my computer.

network encryption:
this one is simple, if you are going on any website where you are transfering information... make sure you are using https:// instead of http://
this means that the data is being encrypted through a secure socket layer.

interesting stuff! I'll be sure to read through your blog, and check back regularly :)

Thanks for this info about encryption. It's very useful to me.

This is some good stuff! :)
keep it up

Good to know. please do your next post on how to make your "unwanted" documents disappear.

Everything is pretty nice, but I really hope you mistyped when you said: "now you should be able to mount your file, and it should appear in my computer."

Very nifty technique to use.

DWei said...

I've heard about this and was considering getting it.

Your review has fully convinced me however.

Yea, I use truecrypt with aes 256.

Do you know of anything else or better? I know of a few paid for programs like filelock. But TC still seems better overall.
