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

Demonstrates how to compute:

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

Ruby

require 'chilkat'

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

password = "secret"

crypt = Chilkat::CkCrypt2.new()
crypt.put_HashAlgorithm("SHA-1")
crypt.put_EncodingMode("base64")

# Generate a 16-byte random nonce
prng = Chilkat::CkPrng.new()
bd = Chilkat::CkBinData.new()
prng.GenRandomBd(16,bd)

# Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
dt = Chilkat::CkDateTime.new()
dt.SetFromCurrentSystemTime()
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...
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")

passwordDigest = crypt.hashBdENC(bd)

print "Base64 password digest = " + passwordDigest + "\n";
