What Is Password Hashing?

Password hashing is the practice of storing a one-way mathematical fingerprint of a password instead of the password itself, so the original text can never be read back out of the stored data. When a user sets a password, the system hashes it and saves the fingerprint. At sign-in, it hashes what was typed and compares fingerprints. EDGEBIC uses PBKDF2 with SHA-256, a widely recommended scheme, so credentials stay protected even if the underlying data is copied.

EDGEBIC by User Solutions hashes every password automatically the moment it is set or changed. This article defines the term and how the protection works. For where accounts and passwords are managed, see how EDGEBIC handles users and roles.

How It Works

A hash function turns any input into a fixed-length fingerprint that is quick to compute forward and effectively impossible to run backward. Storing the fingerprint rather than the password means that reading the stored value tells an attacker nothing they can use to sign in.

EDGEBIC uses PBKDF2 with SHA-256. Three properties make it strong:

• A unique salt per password. A random value is mixed in before hashing and stored with the result. Two users who both choose the same password still produce completely different stored fingerprints, which defeats the precomputed lookup tables attackers use to reverse common passwords.
• A high iteration count. The algorithm is run many thousands of times over, deliberately slowing each computation. That is invisible on a single legitimate sign-in but makes brute-force cracking of stolen fingerprints expensive at scale.
• A constant-time comparison. When comparing fingerprints at sign-in, the check takes the same amount of time whether the guess is close or far off, so an attacker cannot learn anything from how long a response takes.

The salt and the iteration count are embedded in the stored hash itself. That lets EDGEBIC raise the work factor later and upgrade older hashes automatically, without ever knowing anyone's actual password.

A Concrete Example

Think of a hash like a paper shredder that turns a document into a unique pile of confetti. Anyone can feed the same document in and get the same distinctive pile, so you can confirm a match. But no one can reassemble the confetti back into the original page.

Now add salt. Before shredding, you drop in a different colored slip of paper for each document. Two identical documents now make two visibly different piles, so an outsider cannot even tell that two people submitted the same thing. And the iteration count is like running the confetti through the shredder ten thousand more times: it costs you a moment, but it makes any attempt to reconstruct the original hopeless.

EDGEBIC stores only the pile and the color of the slip, never the page. At sign-in it shreds what you typed, with the same slip, and checks that the piles match.

How EDGEBIC Uses It

When an administrator creates a user or a person changes their own password, EDGEBIC hashes it with PBKDF2 and SHA-256 and stores only the fingerprint, salt, and iteration count. Sign-in compares fingerprints; the password text is never written to disk and never travels beyond the moment it is entered.

Because each hash records its own iteration count, EDGEBIC can quietly upgrade an older, weaker hash to the current work factor the next time that user signs in successfully, so stored strength improves over time with no mass reset. Hashing is one layer among several: it works alongside account lockout and password policy to protect sign-in, and events like password changes are recorded in the security audit log.
