"WebAug 16, 2024 · This roughly estimates to 50%. Thus, you will have a hash collision at every N/2 hashes. For example:- MD5 will suffer from hash collision after 2⁶⁴ hashes (because its sample space is 2¹²⁸). This can be exploited and such an attack is called Birthday Attack and is easier than a brute force attack. BIRTHDAY ATTACK " - Birthday attack vs collision attack
