I dont think it is possible to decrypt a SHA256 encrypted message since SHA256 is an hash algorithm which only provides uni-directional encryption
in your case, I recommended encrypt with 3-des to ensure speed, then compress it using ZIP algorithm, store it in database or other medium, ZIP is a reversable compression alogrithm so that you can expand the data once you retrieve it from your persistence medium, also 3-des is symmetric...Leave a comment:

static void show(params object[] b)
the "params" keyword allows a method to have variable-count arguments, you can call it like
static void show(1, 2, 3)
this invocation gives the method 3 arguments (1, 2 and 3)
in the method arguments is encapsulated in an array, so b is an array of object
