WebJun 24, 2024 · Solution: Use unpredictable salts. Keep them secret as best as you (practically) can. Conclusion: Use random salt values at least 16 bytes long. Use the same non-deterministic CSRNG you use for generating new keys in order to make them unpredictable and unique. (No need to use more than 32 bytes = 256 bits.) WebA 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
