Hey all,
We abandon the requirement of collision resistance. This is a strange requirement, and is not supported by experience. Collision resistance
we might think of changing the requirement of collision resistance to "collision resistance in input data that is valid ASCII text". The attacks on MD5 used the weak avalanche of the highest-order bit in 32-bit words for producing the collision, basically precluding the possibility of generating colliding ASCII text.
