WebIn cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard … WebSalts protect against making a rainbow table, or some other form of pre-computed attack.

WebApr 22, 2011 · As for a good book, you can try the Handbook of Applied Cryptography ( cacr.math.uwaterloo.ca/hac)(not the same book than "Applied Cryptography" by Schneier). – Thomas Pornin Apr 22, 2011 at 20:54 WebJul 20, 2012 · A salt is not meant to be secret, instead, a salt 'works' by making sure the hash result unique to each used instance. This is done by picking a different random salt value for each computed hash. The intention of the salt is not compromised when it is known; the attacker still needs to attack each hash separately.
WebAug 22, 2024 · salting is adding data to the password (or anything we want to encrypt) to make it harder for people who want to crack it with bruteforce and rainbow tables. for … WebAug 1, 2024 · A cryptographic salt is data which is applied during the hashing process in order to eliminate the possibility of the output being looked up in a list of pre-calculated pairs of hashes and their input, known as a rainbow table. In more simple terms, a salt is a bit of additional data which makes your hashes significantly more difficult to crack
WebApr 23, 2024 · Hashing is a one-way encryption process in cryptography. Passwords that are hashed are basically scrambled and instead of storing the plaintext passwords in a database, the hashes are stored. When you enter your password, it is hashed and then compared with the hashed password in the database. That's how the system validates …
