… has been a wish for a long time. That led to different kind of encryption/decryption algorithms. Earlier version of the encryption algorithms simply replaced a character with another to diffuse unwanted readers. With time, the algorithms have become more advanced. Today, text …
… is transparentencryption of the entire hard disk, i.e. that encryption and decryption of informationis performed automatically and without the user being affected. In this way allinformation is always protected when stored on the hard disk. The aim of this thesis was to evaluate …
… and algorithm. It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation. An …

When the use of encryption amongst the regular computer user grows morewidespread than ever it makes the life of the IT-forensics experts difficult.Hampering the judicial investigations that otherwise could have lead to convictions. In this report we will treat the subject of …
