Tarea 2.

Hola...

Les envio la tarea 2.

Puntos a calificar:
1. Que generaron y publicaron su llave publica. (y generaron la privada)
2. Que se entendio el proceso a seguir para descifrar un sobre digital (sin firma)
3. Que realizaron su programa para cifrar y descifrar con RSA.
4. Que pueden abrir el sobre digital y contestar la pregunta.
5. Que pueden generar un nuevo sobre digital.

Entregar: (por medio del blog):
1. Una llave cifrada con RSA (con mi llave publica), con la que van a cifrar el archivo de forma simetrica.
2. Una firma digital. (especificar con que algoritmo de hash se utilizo)
3. Un archivo cifrado en base 64 que contenga las respuestas adecuadas.
4. La respuesta solo vale un punto en la calificacion (solo es para comprobar que realizaron todo el proceso).

Que les sea leve!

Saludos...


Nota: Esta tarea califica a varias tareas anteriores!!!
