Class: MessageHash
A 32 byte message hash used for signing ECDSA messages.
Example
// A SHA256 hash of the string 'Hello World'
const messageHash = MessageHash.sha256('Hello World');
// A Keccak256 hash of the string 'Hello World'
const messageHash = MessageHash.keccak256('Hello World');
// In case you already have a hashed value you can just call the constructor with it:
const messageHash = new MessageHash('aabbccddeeff00112233445566778899aabbccddeeff00112233445566778899');
