Stolen Laptops and Data

It seems like daily I hear about security breaches, laptops being stolen. All this personal information is being leaked. I dont understand why people dont use encryption ? I admit it seems daunting, but there are programs out that now that require you to click a button. Its that simple. But what standard do you encrypt with ? I personally like AES which stands for Advanced encryption standard. It is FIPS compliant another lovely acronym that stand for federal information processing which means the goverment uses it to secure unclassified data.

If you want to know the ins and outs of the algorithihm here is a paper published by NIST.

AES Text

After finishing the document, I feel like I need another Red bull.

It talks abouts ciphers, bits, plaintext and other goodies. A knowledge of C C++ or Unix is helpfull. There are alot of functions.

XOR is used in the algorithim to encrypt plaintext into ciphertext.

The cipherkey itself can have lengths of 128, 192 or 256 bits.

There is to much math for me, gives me a headache, although I can understand some of the code.
