Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

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

var password = "secret";

var crypt = new CkCrypt2();
crypt.HashAlgorithm = "SHA-1";
crypt.EncodingMode = "base64";

// Generate a 16-byte random nonce
var prng = new CkPrng();
var bd = new CkBinData();
prng.GenRandomBd(16,bd);

// Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
var dt = new CkDateTime();
dt.SetFromCurrentSystemTime();
var created = dt.GetAsTimestamp(false);
bd.AppendString(created,"utf-8");

// This example wishes to calculate a password digest like this:
// Password_Digest = Base64 ( SHA-1 ( nonce + created + SHA-1(password) ) )

// First SHA-1 digest the password...
var passwordSha1 = crypt.HashStringENC(password);
// Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
bd.AppendEncoded(passwordSha1,"base64");

var passwordDigest = crypt.HashBdENC(bd);

console.log("Base64 password digest = " + passwordDigest);
