(JavaScript) Hash Algorithms: SHA-1, HAVAL, MD2, MD5, SHA-256, SHA-384, SHA-512

How to create hashes (message digests) for strings.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var crypt = new CkCrypt2();

var s = "The quick brown fox jumps over the lazy dog";

crypt.HashAlgorithm = "sha1";
crypt.EncodingMode = "hex";

// Other possible EncodingMode settings are: 
// "quoted-printable", "base64","url", and many more..

var hash = crypt.HashStringENC(s);
console.log("SHA1: " + hash);

// Hash using MD2
crypt.HashAlgorithm = "md2";
hash = crypt.HashStringENC(s);
console.log("MD2: " + hash);

// Hash using MD5
crypt.HashAlgorithm = "md5";
hash = crypt.HashStringENC(s);
console.log("MD5: " + hash);

// Note: SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512)

// Hash using SHA-256
crypt.HashAlgorithm = "sha256";
hash = crypt.HashStringENC(s);
console.log("SHA256: " + hash);

// Hash using SHA-384
crypt.HashAlgorithm = "sha384";
hash = crypt.HashStringENC(s);
console.log("SHA384: " + hash);

// Hash using SHA-512
crypt.HashAlgorithm = "sha512";
hash = crypt.HashStringENC(s);
console.log("SHA512: " + hash);

// Hash using HAVAL
// There are two additional properties relevant to HAVAL:
// HavalRounds, and KeyLength.
// HavalRounds can have values of 3, 4, or 5.
// KeyLength can have values of 128, 160, 192, 224, or 256
crypt.HashAlgorithm = "haval";
crypt.HavalRounds = 5;
crypt.KeyLength = 256;
hash = crypt.HashStringENC(s);
console.log("Haval: " + hash);
