#### Whiteboard Notes

[insert_vertical_space the_pixels="10"] Purpose of this Session: Understand the purpose of initialization vectors, seeds and salts and their application to hashing and passwords. Initialization Vectors - Pseudo-random numbers are made by Pseudo-Random Number Generators Hashing can be a simple process but there are many variables to consider that are used to come up with random initialization vectors. Initialization vectors make the process less predictable and harder to crack encryption – though it is not impossible.Hashing – Passwords can be cracked through the use of lookup tables and Rainbow tables. - This is why it is important to “salt” or add additional information/characters to complicate passwords.- Although many hashing algorithms have been broken, it does not mean they are useless. People need to know how to use them in conjunction with other techniques in order to make them useful and harder to break. Listen to/Download the MP3
