WebAdditionally, dictionary attacksare mitigated to a degree as an attacker cannot practically precompute the hashes. However, a salt cannot protect common or easily guessed passwords. Without a salt, the hashed value is the same for all users that have a given password, making it easier for hackers to guess the password from the hashed value: Web1)If two files have the same hash, this guarantees that the files are the same. 2)Hashed passwords are vulnerable to dictionary attacks. 3)DES encryption became breakable when flaws were found in the S-box substitution algorithm. 4)Asymmetric cryptography sidesteps the key distribution problem. 5)Private and public keys need to be kept secret. poodle beagle mix images
