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

Dim crypt As New ChilkatCrypt2

' The output will be Hex, so set the EncodingMode:
crypt.EncodingMode = "hex"

' Set the hash algorithm:
' Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
crypt.HashAlgorithm = "md5"

Dim mac As String

' Set the HMAC key:
crypt.SetHmacKeyEncoded "0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b","hex"
mac = crypt.HmacStringENC("Hi There")
Debug.Print mac

crypt.SetHmacKeyEncoded "Jefe","ansi"
mac = crypt.HmacStringENC("what do ya want for nothing?")
Debug.Print mac
