Hasp constants The Hasp constants are as follows... Hasp (Function) Interrogates an electronic HASP key (HASP-3, HASP-4, MemoHasp or NetHasp). Hasp functions The dongles of Hasp family (Hasp3, Hasp4, NetHasp, memoHasp and Hasp HL) are used to protect the applications developed with WINDEV or WEBDEV... HaspHLDecrypt (Function) Decrypts a character string by using the algorithms of the Hasp key. HaspHLEncrypt (Function) Encrypts a character string by using the algorithms of the specified Hasp key. HaspHLInfo (Function) Returns information about the electronic Hasp key. HaspHLLogin (Function) Connects the application with a Hasp key. HaspHLLogout (Function) Closes the connection of the application to a Hasp key. HaspHLRead (Function) Reads data (character string or buffer) in the internal memory of the Hasp key. HaspHLWrite (Function) Writes data (character string or buffer) into the internal memory of the Hasp key.
