Question

Hello Guys!

i am working on a text cryptography project and i need to know what a vector is relating to vb.net, and how to create a vector

1)What is a vector

2)How to create a vector

Answer 1

You should review System.Security.Cryptography Namespace and perhaps for any cryptography type implemented there is a difference in key and vector requirements.

Like with AES which I would guess would be different than for another method.

Hi, you can use ArrayList or List(Of T):

Answer 3

Typically when someone says "vector" all by itself in the context of a computer program, they are talking about a structure of two or more dimensions.  A Point could be considered a "Vector 2" structure.  When you add a reference to any assembly dealing with 3D, you typically also find a Vector3 structure which is like a Point that also has a Z value in addition to X and Y.

However, you appear to be talking about a Cryptography Initialization Vector, which is something else entirely.  For that, you can review this link to understand the concept, but you should follow the MSDN documentation for the particular cryptography provider that you are using in your code.
