Encryption in simplest terms is changing plaintext into ciphertext; decryption is the process of changing it back.
Encryption should be applied to information you want to protect at rest as well as in transit.
You can use Aescrypt to encrypt individual files and encrypt full disks with options such as Bitlocker and FileVau

This approach added a bit of complexity to early cryptosystems.
One-time pad is considered to be unbreakable since it only uses its cipher code once.
Pseudo-Random Number Generators (PRNGs). This method repeats the random numbers after a given time (pe
They are fast and are also deterministic and are useful in producing a repeatable set of random numbers.
True Random Number Generators (TRNGs). This method generates a true random number and uses some form
process. One approach is to monitor the movements of a mouse pointer on a screen or from the pauses betwee
keystrokes. Overall, the method is generally slow, especially if it involves human interaction, but is non-determi
aperiodic.
Frequency Analysis is cipher cracking methodology that involves identifying patterns and variations in the prob
