2.10 Digest

In this lesson you’ll learn about the Digest module. Digest supplies a number of hash functions—one-way functions that allow us to secure otherwise sensitive data that we want to protect from possible malicious users. For example, passwords should always be hashed and salted before being stored in a local system. Also, hashes are a great way to generate unique symbols for your application.
