Hash wachtwoorden

Auteur: Stijn - 10 juni 2010 - 23:07 - Gekeurd door: Stijn - Hits: 4178 - Aantal punten: (0 stemmen)

Deze simpele klasse hashed je wachtwoord met een gekozen hashalgoritme. De algoritmes kan je terugvinden op deze pagina. Er wordt gebruik gemaakt van een salt. Verander deze waarde dan ook in de klasse naar een zelfgekozen random waarde. Je kan ook de positie veranderen waar de salt moet komen. Dus je bent niet gebonden aan vooraan of achteraan.

Voorbeeld (MD5 hash met een andere salt op positie 0):
