I have a question about what peoples … WebSalt is random data that helps protect against dictionary and other precomputation attacks. Generally, salt is used in password-based systems and is concatenated to the front of a password before processing. Password systems often use a one-way hash function to turn a password into an “authenticator.”

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 passwords in storage. Historically, only the output from an invocation of a cryptographic hash function on the password was stored on a system, but, over time, additional … WebHashing and salting of passwords and cryptographic hash functions ensure the highest level of protection. By adding salt to your password, you can effectively thwart even the …
WebThe salt is not a cryptographic secret, so storing it in your table is no problem. The only purpose of a salt is to ensure that when different instances of the same item are hashed (or encrypted) that you get a different result. – Michael Burr Oct 8, 2008 at 18:44 3 WebIn cryptography, salt refers to some random addition of data to an input before hashing to make dictionary attacks more difficult.

WebA salt is a unique, randomly generated string that is added to each password as part of the hashing process. As the salt is unique for every user, an attacker has to crack hashes one at a time using the respective salt rather than calculating a hash once and comparing it against every stored hash.
