The hashing process can provide integrity, authentication, and non-repudiation. In this video, you’ll learn how hashes are created and how to use digital signatures. << Previous Video: Obfuscation Next Video: Blockchain Technology >> A cryptographic hash is used to represent data as a short string of text. Sometimes you’ll hear this referred to as a […]

Obfuscation can be used in IT security to hide information in unique ways. In this video, you’ll learn about steganography, tokenization, and data masking. << Previous Video: Encryption Technologies Next Video: Hashing and Digital Signatures >> Obfuscation is a process, where you take something that normally would be very easy to understand, and you make

Encryption technologies provide secure key storage, cryptographic functions, and data privacy. In this video, you’ll learn about HSMs, TPMs, secure enclave, and more. << Previous Video: Key Exchange Next Video: Obfuscation >> If you were to look on a modern motherboard, you would find a chip or a subsystem called a Trusted Platform Module, or

A secure key exchange method is critical for real-time encryption. In this video, you’ll learn how a symmetric key can be derived from a public and private key pair. << Previous Video: Encrypting Data Next Video: Encryption Technologies >> As we’ve been discussing in our previous videos, we’ve talked about how important it is to
