Cryptography Fundamentals: Applying Cryptography Overview/Description Target Audience Prerequisites Expected Duration Lesson Objectives Course Number Expertise Level Overview/Description
Using cryptography is far more than just selecting an algorithm and calling the encrypt or decrypt method. In this course, you will learn about the modes of operation for encryption algorithms as well as when particular algorithms are best suited to the data being protected. You will also learn how to manage cryptographic keys and how cryptanalysis can be used against weak cryptographic systems (even when using strong algorithms).
Target Audience
System administrators, database administrators, security professionals, software developers, and anyone who has to work with compliancy or regulations that require data protection

Lesson Objectives Cryptography Fundamentals: Applying Cryptography
start the course
describe and identify data that has been encrypted using the ECB mode
specify how Cipher Block Chaining uses an IV, or initialization vector, to make data appear random
describe how Propagating Cipher Block Chaining mode improved on CBC by causing small changes to each block encrypted
describe the Cipher Feedback mode and how it builds on CBC and makes a block cipher into a stream cipher
describe the Output Feedback mode and how it can use the same process for encryption and decryption
describe the Counter mode and how It can be used for parallelizing encryption and decryption
use a simple AES implementation to encrypt and decrypt data and compare the results to the NIST standard to confirm operation of the algorithm
describe how the DES and 3DES algorithms work to encrypt and decrypt data
describe the Blowfish block cipher algorithm and its properties
