# 2. Symmetric Key Encryption
|
||
|
|
|
||
|
|
## Outline
|
||
|
|
The key concepts involved in this unit are:
|
||
|
|
|
||
|
|
* Defining key entropy;
|
||
|
|
* Key generators (such as using hashing methods to generate keys based on passphrases);
|
||
|
|
* Symmetric key methods (AES, Twofish, 3DES, RC4 and ChaCha20);
|
||
|
|
* Stream or block encryption;
|
||
|
|
* Symmetric key modes (ECB/CBC/OFB);
|
||
|
|
* Salting/IV.
