This chapter covers the following subjects:
• Cryptography Concepts—This section covers the basic terminology of cryptography including encryption, ciphers, and keys. It also discusses private versus public keys, symmetric versus asymmetric encryption, and public key encryption.
• Encryption Algorithms—This section delves into the various symmetric algorithms, such as DES and AES, and some of the popular asymmetric algorithms such as RSA and elliptic curve.
• Hashing Basics—Here, we investigate the most common way to verify the integrity of files: hashing. We cover basic hashing concepts and cryptographic hash functions, such as MD5, SHA, and NTLM.
This chapter covers the CompTIA Security+ SY0-301 objectives ...
