Generating a Hash with JavaScript

Use HashUtil.generate() to create a hex hash of a message passing through a channel in JavaScript contexts: var hash = HashUtil.generate(message);

We provide 3 overloaded versions:

• HashUtil.generate(Object)
  • Takes in any object and returns a hex hash of the object as a String. This defaults to using the platform's default character encoding and the SHA-256 hashing algorithm.
  • Example

    • HashUtil.generate("Hello, World!")

• HashUtil.generate(String, String, String)
  • Takes in data as a string, a character encoding as a string, and a hashing algorithm as a string and returns a hex hash of the data as a string.
  • Example

    • HashUtil.generate("Hello, World!", "UTF-8", "SHA-256")

• HashUtil.generate(byte[], String)
  • Takes in data as a byte[] and a hashing algorithm as a string and returns a hex hash of the data as a string.
  • Example

    • HashUtil.generate("Hello, World!".getBytes(), "SHA-256")
