Procedure Test
    Handle hoCrypt
    String sMac
    Boolean iSuccess

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

    Get Create (RefClass(cComChilkatCrypt2)) To hoCrypt
    If (Not(IsComObjectCreated(hoCrypt))) Begin
        Send CreateComObject of hoCrypt
    End

    // The output will be Hex, so set the EncodingMode:
    Set ComEncodingMode Of hoCrypt To "hex"

    // Set the hash algorithm:
    // Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
    Set ComHashAlgorithm Of hoCrypt To "md5"
    Set ComMacAlgorithm Of hoCrypt To "hmac"

    // Set the HMAC key:
    Get ComSetMacKeyEncoded Of hoCrypt "0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b" "hex" To iSuccess
    Get ComMacStringENC Of hoCrypt "Hi There" To sMac

    Get ComMacStringENC Of hoCrypt "what do ya want for nothing?" To sMac
