Optionally, you can pass a callable setter that It returns True if they match,įalse otherwise. Plain-text password to check, and the full value of a user’s passwordįield in the database to check against. Password to the hashed password in the database, use the convenienceįunction check_password(). If you’d like to manually authenticate a user by comparing a plain-text check_password( password, encoded, setter = None, preferred = 'default') ¶ You can use them independentlyįrom the User model. To mitigate this by upgrading older password hashes. Request for a nonexistent user (which runs the default hasher). With a password encoded in a non-default algorithm and the duration of a login Updated when increasing (or decreasing) the number of PBKDF2 iterations, bcryptīe aware that if all the passwords in your database aren’t encoded in theĭefault hasher’s algorithm, you may be vulnerable to a user enumeration timingĪttack due to a difference between the duration of a login request for a user Unmentioned algorithms won’t be able to upgrade. Sure never to remove entries from this list. PASSWORD_HASHERS, so as you upgrade to new systems you should make However, Django can only upgrade passwords that use algorithms mentioned in This means that old installs of Django will getĪutomatically more secure as users log in, and it also means that youĬan switch to new (and better) storage algorithms as they get invented. The preferred algorithm, Django will automatically upgrade the algorithm When users log in, if their passwords are stored with anything other than If a stored password names anĪlgorithm not found in PASSWORD_HASHERS, trying to verify it will The algorithm name in the stored password. Put your preferred algorithm first in PASSWORD_HASHERS.įor verifying passwords, Django will find the hasher in the list that matches To store new passwords with a different algorithm, This is a list of hashing algorithmĬlasses that this Django installation supports.įor storing passwords, Django will use the first hasher in If you do, please read on:ĭjango chooses the algorithm to use by consulting the Again, most users shouldn’t need to do this – if However, depending on your requirements, you may choose a differentĪlgorithm, or even use a custom algorithm to match your specific Sufficient for most users: it’s quite secure, requiring massive Password stretching mechanism recommended by NIST. Salt is the random seed used and the hashīy default, Django uses the PBKDF2 algorithm with a SHA256 hash, a The algorithm is one of a number of one-way hashing or password storageĪlgorithms Django can use see below. Those are the components used for storing a User’s password, separated by theĭollar-sign character and consist of: the hashing algorithm, the number ofĪlgorithm iterations (work factor), the random salt, and the resulting password
