[DLL] HashAlgorithm 1.0.0.1
Publicado: 22 Mar 2013 14:21
Información:
Buenas amigos de AMSSpecialist despues de mucho tiempo sin tocar Visual Studio he retomado algunos proyectos que tenia a medio hacer, en este caso os traigo una versión evolucionada de la dll HashMD5 pero con algunas funciones mas. Esta DLL funciona perfectamente a excepcion del algoritmo SHA que me trae de cabeza con sus putos randoms... tengo que mirarla bien, espero que os guste y la disfrutéis....
