In cryptography, a random sequence of data attached to a password or other input message before hashing. If two users create the same password, their hashes will be identical—without a salt. With it, however, the hashes will be different even if the password itself is the same.
A salt improves security and helps protect against precomputed-hash attacks: they become largely ineffective because the hash has to be computed anew for each password and each unique salt.
In the context of cryptocurrencies, a salt may be used wherever user data needs to be protected, e.g., when storing passwords, credentials, seed phrases in encrypted form, or other sensitive information in wallets, exchanges, and related services.
