Dim crypt As New Chilkat.Crypt2

// 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 = "sha256"
crypt.MacAlgorithm = "hmac"

Dim mac As String

// Set the HMAC key:
Dim success As Boolean
success = crypt.SetMacKeyEncoded("The_API_Secret","ascii")
mac = crypt.MacStringENC("The quick brown fox jumps over the lazy dog")
System.DebugLog(mac)
