comment Are all unsalted password hashes inherently insecure?
@Keltari Salt should be random, and is normally stored alongside the password hash. If you have broken into a database and stolen a user's password hash, you probably have the salt too. It is not the salt's job to be secret; it is the salt's job to increase the space of possible hash inputs in order to make precomputation attacks such as rainbow tables infeasible.

comment “Inverted” asymmetric encryption
With your role reversal of private & public keys, you have essentially reinvented digital signatures. Now you just need to read up on them, align your terminology with the rest of the world, and understand how your idea has already been refined over the last few decades.

comment Password Storage - Self Encryption vs Hashing?
The original Unix crypt implementation got around the problem of variable length by using the password as a key to encrypt a fixed block of data; see en.wikipedia.org/wiki/Crypt_(C)

comment What are the differences between dictionary attack and brute force attack?
In a nutshell, a dictionary attack is a kind of brute force attack where the attacker is able to rate keys in order of most probable ... least probable, compile a list of the most probable (the dictionary), and test them in that order.
