(Node.js) Hash Algorithms: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

How to create hashes (message digests) for strings.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM

    // There are two additional properties relevant to HAVAL:
    // HavalRounds, and KeyLength.
    // HavalRounds can have values of 3, 4, or 5.
