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.
