    Hash algorithms are one way functions. They turn any amount of data intoa fixed-length "fingerprint" that cannot be reversed. They also have theproperty that if the input changes by even a tiny bit, the resulting hash iscompletely different (see the example above). This is great for protectingpasswords, because we want to store passwords in a form ...

    The simplest way to crack a hash is to try to guess the password, hashing each guess, and checking if the guess's hash equals the hash being cracked. If the hashes are equal, the guess is the passw...

    Rainbow tables are a time-memory trade-off technique. They are like lookup tables, except that they sacrifice hash cracking speed to make the lookup tables smaller. Because they are smaller, the so...

    Lookup tables and rainbow tables only work because each password is hashed theexact same way. If two users have the same password, they'll have the samepassword hashes. We can prevent these attacks by randomizing each hash, so thatwhen the same password is hashed twice, the hashes are not the same. We can randomize the hashes by appending or prepen...

    The most common salt implementation errors are reusing the same salt in multiplehashes, or using a salt that is too short.

    This section covers another common password hashing misconception: wackycombinations of hash algorithms. It's easy to get carried away and try tocombine different hash functions, hoping that the result will be more secure. Inpractice, though, there is very little benefit to doing it. All it does iscreate interoperability problems, and can sometimes...

    Because hash functions map arbitrary amounts of data to fixed-length strings,there must be some inputs that hash into the same string. Cryptographic hashfunctions are designed to make these collisions incredibly difficult to find.From time to time, cryptographers find "attacks" on hash functions that makefinding collisions easier. A recent example ...

    This section describes exactly how passwords should be hashed. The firstsubsection covers the basics—everything that is absolutely necessary. Thefollowing subsections explain how the basics can be augmented to make the hasheseven harder to crack.

    Password hashing protects passwords in the event of a security breach. It doesnot make the application as a whole more secure. Much more must be done toprevent the password hashes (and other user data) from being stolen in the firstplace. Even experienced developers must be educated in security in order to write secure applications.A great resource...

    What hash algorithm should I use?

    1. Well-designed key stretching algorithms such as PBKDF2, bcrypt, and scrypt. 2. OpenWall's Portable PHP password hashing framework 3. My implementations of PBKDF2 in PHP, C#, Java, and Ruby. 4. Secure versions of crypt($2y$, $5$, $6$) 1. Fast cryptographic hash functions such as MD5, SHA1, SHA256, SHA512, RipeMD, WHIRLPOOL, SHA3, etc. 2. Insecure versions of crypt ($1$, $2$, $2x$, $3$). 3. Any algorithm that you designed yourself. Only use technology that is in the public domain and has bee...

    How should I allow users to reset their password when they forget it?

    It is my personal opinion that all password reset mechanisms in widespread use today are insecure. If you have high security requirements, such as an encryption service would, do not let the user reset their password. Most websites use an email loop to authenticate users who have forgotten theirpassword. To do this, generate a random single-usetoken that is stronglytied to the account. Include it in a password reset link sent to the user'semail address. When the user clicks a password reset l...

    What should I do if my user account database gets leaked/hacked?

    Your first priority is to determine how the system was compromised and patchthe vulnerability the attacker used to get in. If you do not have experienceresponding to breaches, I highly recommend hiring a third-party security firm. It may be tempting to cover up the breach and hope nobody notices. However, trying to cover up a breach makes you look worse, because you're puttingyour users at further risk by not informing them that their passwords and otherpersonal information may becompromised....
