Timeline for If I concatenate two colliding SHA-256 messages with the same prefix and suffix, will the resulting hash output still collide with each other?

| Mar 15, 2020 at 15:58 | comment | added | Biology nerd | So if x1 and x2 collide in the first 80 bits, and I perform a length extension attack to produce H(s∥x1) and H(s∥x2) - then H(s∥x1) and H(s∥x2) won't collide in the first 80 bits either? I'm wondering why this would be the case........ | |
