WebAug 27, 2024 · Birthday Problem That is a set of randomly chosen people some pairs of them will have the same birthday in the year the cryptography. Thus, the pigeonhole principle in the probability reaches 100% when the number of people reaches 367 since there are 366 possible birthdays, including February 29 this year in cryptography. WebMar 23, 2024 · In cryptography, this is called a Birthday Attack. What If 1234 Is Mapped To The Same Hash As My Strong Password? The Birthday Problem is a good party trick because “23 people” is way fewer than you’d expect... But that’s not relevant, is it? What you want to know is the chance of someone sharing a birthday (hash value) with you.
