Dim crypt As ChilkatCrypt2
crypt.Initialize("crypt")

'  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 = "sha-1"
crypt.MacAlgorithm = "hmac"

Dim mac As String

'  Set the HMAC key:
crypt.SetMacKeyEncoded("0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b", "hex")
