Hashing in Java

Hashing is an interesting technique we need to use in standard java solutions such as services and microservices. SHA-256 is a secure hash algorithm for data you want to hash. Often this technique can be used for Passwords or high entropy PII Data. For this blog post, I want to share with you guys how we can create secure hashes in java using SALTS. We will be experimenting with 4 flavors of Hashing(SHA-256) being: Standard Java API, Guava, Apache Commons Codec, and Bouncy Castle. Today we will see a Java video I recorded going through the API. So Let’s get started.
