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 de lecture de la cellule 10 de la clé :
// la numérotation commence à 0
NumFonc = 3	// Fonction READ_WORD
Entier1 = 10
Hasp(NumFonc, SeedCode, Lpt, Passe1, Passe2, ...
	&Entier1, &Entier2, &Entier3, &Entier4)
IF Entier3 = 0 THEN
	Info("Contenu adresse mémoire 10 de la clé>" + Entier2 + "<")
ELSE
	Info("Erreur : code retour = " + Entier3)
END

Syntax

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

<FunctionNum>: Integer

Number of the HASP function to run:
1: Checks Hasp key.
2: <SeedC> executes a program in the key that returns 4 different integers for each value entered. This is used to check the presence of key and whether it is not simulated.
3: Read the contents of the key.
4: Write the contents of the key.
5: Returns key content and parallel port information.
6: Returns the key identifier.
50: Reads a block of data from the key.
51: Writes a block of key data.
For functions for reading and writing a fixed string (Ch) in the key: <Ent3> = 0, <Ent4> = &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.

IdHigh: to reconstitute the key identifier id = idHigh*65536+idLow
Status: function execution report
r1...r4: integer containing magic values for a given seed code and key.
