CISSP training video: Cryptography algorithms and encryption keys

In this CISSP Essentials Security School presentation, Shon Harris explains the basics of the Cryptography domain, including definitions, cryptography algorithms, encryption keys and more.

The Certified Information Systems Security Professional Cryptography domain within the Common Body of Knowledge (CBK) is often considered the hardest of all the CISSP domains in the entire program, yet it remains one of the most critical. Sensitive data must be protected during transit; cryptography is imperative to achieving this.

In this special multimedia presentation from SearchSecurity's CISSP Essentials Security School, expert CISSP exam trainer Shon Harris, CEO and founder of Logical Security, offers a comprehensive overview of the complex cryptography section of the CBK.

Harris begins by explaining what cryptography is, including its goals, services and functionality within the information security industry. She continues by explaining numerous cryptography definitions -- including plaintext, ciphertext and cryptology -- and discusses what a cryptosystem is and how to calculate its strength.

The presentation also offers an in-depth explanation of asymmetric vs. symmetric cryptography and defines a number of cryptography algorithms, including the DES, Blowfish, AES, Diffie-Hellman, RSA and ECC. Harris concludes by explaining the topics of encryption key management and digital envelopes.
