Visual Basic Tutorial: How to Encrypt and Decrypt Data
 
13:09
download code: http://www.krob636.com/codesamples/xor.zip This video shows how you can make a simple 'encryption' and 'decryption' program by shifting the ASCII codes. This scrambles the text, making it unreadable for people who were not meant to see it. Note: This encryption may be all you need to conceal your information within your text; however, it can be decoded by performing frequency analysis on your cipher-text (encrypted text). Frequency analysis relies on a cipher failing to hide the fact that certain characters of the alphabet appear more often than others. Following this tutorial, I will be making a tutorial on stronger encryption schemes.

Affine Cipher - Decryption (Known Plaintext Attack)
 
07:04
In this video I talk about ways to decrypt the Affine Cipher when the key is NOT known. Specifically, I go over an example of the known plaintext attack. 3^(-1) = 9 (mod 26) math worked out (Euclidean Algorithm): 1. Forwards: 26 = 3(8) + 2 3 = 2(1) + 1 2. Backwords: 1 = 3 - 2(1) 1 = 3(1) - (26 - 3(8))(1) 1 = 3(1) - 26 + 3(8) 1 + 26 = 3(9) 1 (mod 26) = 3(9) Hence 9 is the inverse.
