Web•A birthday attack is an attack on hashed password that utilizes the same logic as the birthday problem. Which is to say, even if there are many different possible hashing outputs, you are likely to find two different inputs with the same hash. • •The amount of attempts required for a probable match is less than one might think, for example: WebA "normal", brute-force attack on a cryptographic hashing algorithm should have a complexity of about for a hash algorithm with an output length of bits. That means it …
