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. WebMuch like symmetric-key ciphers are vulnerable to brute force attacks, every cryptographic hash function is inherently vulnerable to collisions using a birthday attack.
