Although blockchain technology is often associated with cryptocurrencies, there are many other implementations. In this video, you’ll get an overview of the processes used with blockchain technologies. << Previous Video: Stream and Block Ciphers Next: Cryptography Use Cases >> A blockchain is a distributed ledger. It’s a way to keep track of a particular event. […]

We use stream and block ciphers to efficiently protect our important data. In this video, you’ll learn about stream cipher methods and block cipher modes of operation. << Previous Video: Quantum Computing Next: Blockchain Technology >> When you want to encrypt some information, there are a number of different techniques you can use to take

Quantum computing is quickly changing our perspective on technology and cryptography. In this video, you’ll learn the basics of quantum computing and how our cryptography changes when using quantum computing. << Previous Video: Steganography Next: Stream and Block Ciphers >>   An emerging technology in computing is quantum computing. This is computing based on quantum

It’s sometimes easier to transfer secret information through the use of a concealment. In this video, you’ll learn about obfuscation, steganography, and how to hide data inside of image, audio, and video files. << Previous Video: Cryptographic Keys Next: Quantum Computing >>   Obfuscation is the process of taking something that would commonly be relatively

Our cryptographic keys are often the only unknown variable when protecting data or creating digital signatures. In this video, you’ll learn about key strength, key exchange, and how to protect different sessions with dynamic keys. << Previous Video: Hashing and Digital Signatures Next: Steganography >>   Cryptography is an interesting science because it allows us

We use hashing and digital signatures extensively to ensure safe and secure data transfers. In this video, you’ll learn about hashing data, salting a hash, and creating a verifying digital signatures. << Previous Video: Symmetric and Asymmetric Cryptography Next: Cryptographic Keys >>   A hash is designed to take any type of input, whether that’s

Symmetric and asymmetric cryptography are the fundamentals of our data security. In this video, you’ll learn about symmetric encryption, asymmetric encryption, creating the key pair, and sending data securely using both symmetric and asymmetric cryptography. << Previous Video: Cryptography Concepts Next: Hashing and Digital Signatures >> Let’s begin our conversation of the differences between symmetric

The fundamentals of cryptography apply to many aspects of IT security. In this video, you’ll learn about cryptographic concepts such as keys, lightweight cryptography, key stretching, and homomorphic encryption. << Previous Video: Secure Data Destruction Next: Symmetric and Asymmetric Cryptography >>   The word cryptography is derived from the Greek word kryptos, which means hidden

There are many ways to permanently remove data from a storage device. In this video, you’ll learn about physical destruction, purging data, and data wiping. << Previous Video: Secure Areas Next: Cryptography Concepts >>   As a security professional, you’ll be tasked with knowing what data can be destroyed and what data must not be
