WebIn a cryptographic hash function, collisions should in theory be not significantly faster to find than in a brute force attack. Such a brute-force attack is based on the birthday paradox, and it would require expected 2^80 computations to produce a SHA-1 collision. Of course, collisions should also be computationally infeasible to find in practice. WebA birthday attack is a method of forging digital signatures that exploit this property of hash collisions.
