I disagree here. I doubt SHA2 or any modern hash will become weak within our lifetime. JP Aumasson, who is one of the experts of the field, agrees with me on that:

I doubt yours because as far as I can tell it's basically argument from authority ("JP Aumasson said so!") [0] http://valerieaurora.org/hash.html http://valerieaurora.org/hash.html
