WebOct 23, 2024 · Salts, nonces, and IVs are all one-time values used in cryptography that don’t necessarily need to be secret, but still lead to additional security. 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.)
