WebFeb 5, 2015 · As a general rule of thumb, the primary focus of cryptographic PRNGs is to keep the attacker as far away from the internal values (like seeds) as humanly possible. As an example, the reason a Mersense Twister is not considered cryptographic is because you can recover the seed with 624 sequential outputs, and then you can perfectly predict the ...

Web21. The usual answer is that a salt can be make public; if that was a problem, then the salt would not be called a "salt" but a "key". In some protocols, unauthenticated obtention of the salt is the norm, and is not considered to be a problem. E.g. with SRP, a password-authenticated key exchange, where any salting and hashing must necessarily ... WebJun 15, 2015 · Only when the mechanism of the code -- the "how it works" -- is more important to the reader than the semantics -- the "what its for". So basically in a line like. byte [] salt = new byte [max_length]; or. int max_length = 32; the type of the variables does not add any value to the code. It is too obvious what the assigned type is, using the ...
WebMar 24, 2024 · Thus you want a bare minimum of 40 bits of uniqueness, which requires an 80-bit salt. The current trend is to simply use a 128-bit random number, making the chance of a salt collision "cryptographically unlikely" for the near term. 80 bits would require random 14 alphanumeric characters. 128 bits requires 22 characters. WebIn cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, …
