The cryptographic hash provides some important validation functions. In this video, you’ll learn the basics of cryptographic hashing and how they can be used to provide confidentiality, authentication, non-repudiation, and integrity.
One of the powerful features of modern cryptography is the ability to digitally “sign” your files and documents. In this video, you’ll learn how non-repudiation can be used to ensure the authenticity and integrity of your documents.
The topic of cryptography is one of the most comprehensive in network security. In this video, you’ll learn about the history of cryptography and some of the early methods of encrypting and decrypting messages.
