The keys to cryptography
- In my view, the best way to understand the details of how a blockchain works is to break it down into its component parts. In this video, I'm going to explain cryptography and the role of keys in blockchain. The term cryptography is a Greek word, which means secret or hidden writing. At a basic level, it's a way to create a message so that only authorized individuals are able to access and read it. For everyone else, it'll be gibberish. Using cryptography, a plain text message, one that can be read is converted to cipher text, one that can't. It is said to be encrypted. When the message arrives at its destination, it must be decrypted so that it can be read again. Cryptography predates computing, and over centuries, many cryptographic tools have been used to encrypt and decrypt. Today, cryptography, within computing, is essential for data privacy and security. One of the most popular forms of computing-based…
