Cryptography is the technique of taking plain, legible text and implementing an algorithm to it to encrypt it to produce ciphertext, which seems to be gibberish before it is decrypted. To maintain confidentiality, encryption is used.
In this chapter, you will take a look at the encryption algorithms used today and how you can apply encryption to maintain two of the three security principles—confidentiality and integrity. You will learn about public key cryptography, digital signatures, and how to examine encrypted ...
