Securing Keys

이번엔 두번째 단계: collision을 풀어보도록 하겠다. 문제를 확인해보면 위와 같다. MD5 Hash collision 에 관한 문제임을 힌트로써 얻을 수 있었다. Collision Attack In cryptography, a collision attack on a cryptographic hash tries to find two inputs producing the same hash value, i.e. a hash collision. This is in contrast to a preimage attack where a specific target hash value is specified. There are roughly two types of collision attacks: Classic..
