Title: Chicken and egg hash Post by: yokosan on April 22, 2013, 10:55:56 AM Bit of a strange question but it may be semi-relevant to this forum.
Let's say I want to create a program. This program will work out the SHA-256 hash of itself and use the hash to check it's own validity. In order to do this you will need to know the hash of the code before the code has been written, so how would you do it? (almost) impossible?
