Hasp (Function)

In french: Hasp

Interrogates an electronic HASP key (HASP-3, HASP-4, MemoHasp or NetHasp). Hasp is used to protect the applications developed in WINDEV or WEBDEV by Hasp keys.

Remarks:

To use Hasp, you must be familiar with the operating mode of Hasp keys and have the relevant documentation.
Hasp is not available in 64-bit mode. We recommend that you use the HaspHLxxx functions.

Example

// Test for reading the cell 10 of key:
// the numbering starts from 0
FuncNum = 3 // READ_WORD function
Int1 = 10
Hasp(FuncNum, SeedCode, Lpt, Pass1, Pass2, ...
&Int1, &Int2, &Int3, &Int4)
IF Int3 = 0 THEN
Info("Content address memory 10 of key>" + Int2 + "<")
ELSE
Info("Error: return code = " + Int3)
END

Syntax

Hasp(<FunctionNum> , <SeedC> , <LPT> , <Pass1> , <Pass2> , <Int1> , <Int2> , <Int3> , <Int4>)

<FunctionNum>: Integer

Number of the HASP function to run:
1: Checks the HASP key.
2: <SeedC> is used to run a program in the key that will return 4 different integers for each value passed. This is used to check the presence of key and whether it is not simulated.
3: Read the key content.
4: Write the key content.
5: Returns the key content and information about the parallel port.
6: Returns the key identifier.
50: Reads a block of data in the key.
51: Writes a data block in the key.
For the functions used to read and write a fixed string (Str) in the key: <Int3> = 0, <Int4> = &Ch.

<SeedC>: Integer

Used only if <FunctionNum> = 2.

<LPT>: Integer

Port number. If <LPT> = 0, Hasp seeks the key on the "proper" parallel port (without having to specify its number).

<Pass1>: Integer

Parameter supplied by the manufacturer of the key. This parameter guarantees the security of the data stored in the key.

<Pass2>: Integer

Parameter supplied by the manufacturer of the key. This parameter guarantees the security of the data stored in the key.

<Int1>: Integer

Values passed by reference (with the & operator). These values can be read in input and/or modified in output.

<Int2>: Integer

Values passed by reference (with the & operator). These values can be read in input and/or modified in output.

<Int3>: Integer

Values passed by reference (with the & operator). These values can be read in input and/or modified in output.

<Int4>: Integer

Values passed by reference (with the & operator). These values can be read in input and/or modified in output.

Type: type of key
Data: data to read or write
Lng: length of the data to read/write in the key
Segm: 0
OffSet: &Text where Text is a string containing the information to read or write
Idlow: to rebuild the identifier of the key id = idHigh**65536+idLow
IdHigh: to rebuild the identifier of the key id = idHigh**65536+idLow
Status: status report of the function execution
r1...r4: integer containing the magic values according to a given Seed code and key.
