Hello I have my existing web application in Django. Now I am migrating to node js and I am using the bcrypt algorithm for hashing the password. So, the problem is: In Django , it uses pbkdf2_sha256 algorithm for storing password. How do I migrate password from Django so that my matching algorithm match the peviously stored password correctly?
Use the node.js crypto.pbkdf2 function, see crypto.pbkdf2. PBKDF2 is the suggested passsword hashing method in the NIST SP 800-63-3 Draft document.

So I'm working on a mobile app that's driven by a node.js API. My question is, for hashing/storing passwords would it be better to hash them in the node API (with Bcrypt) then send this to the Postgres database, or should I send the plaintext password to the database and hash it using the crypt() function that is in pgcrypto.
If you send it to the database in plaintext, that is just one more spot where it can be accidentally logged or leaked, or spotted in transit. Why do that if you don't need to? If node.js has a trustworthy bcrypt API, then use it rather than using pgcrypto's.
I have a Laravel existing project where they use Laravel default encryption (i.e Hash::make('')) for user registration,so in database they saved the data with this encryption format.
Now I am creating API's using Node for the same MySQL database.So for those password decryption I have used Node bcrypt package.But the decryption is not working and I am getting error for JWT authentication token.I have used "algorithm": "RS256" for this Node API.So can anyone tell me if I did something wrong or I have to choose another package(in node) or any other algorithm(in node).
I think that is becrypt. Now when I am creating the API's with Node I have used Node be
Passwords in Laravel are hashed, which is different to encrypt them, because Hash is not reversible, when encryption can be reversed.
Furthermore, in order to let Node be able to decrypt encrypted data, you should share with Node the key that Laravel has used to encrypt that data, and that's absolutely very dangerous, because everyone than can have that key, and so if he finds a breach in you sql, like a possibility to run SQL injection, than he can use that key to decrypt that data
I've been struggling with this for some time now, hopefully someone has done this before and can help me on my way. I went to the Firebase people to request the scrypt params in order to migrate our user authentication away from Firebase to our own server. Now I got those params, but I have no clue as how they should map towards the node scrypt package (https://www.npmjs.com/package/scrypt). The Firebase params are of the following format:
hash_config: {
algorithm: SCRYPT,
base64_signer_key: asdf1234
base64_salt_seperator: xxxx
rounds: 123456
mem_cost: 098765
}
Somehow these should map onto the nodejs scrypt params, but I can't find the similarities. Any help would be much appreciated!
Struggled a lot with getting scrypt work properly. The documentation from here https://github.com/firebase/scrypt#password-hashing looks like outdated. Decided to share knowledge how we did things correctly in our team.
Working command
scrypt {key} {salt} {saltSeparator} {rounds} {memcost} [-P]
No need for salt+separator concatenation and base64 manipulations.
Firebase uses a custom version of Scrypt for user authentication. We take the derived key from standard scrypt, and then AES encrypt it with a "pepper", stored with the hashed password.
We just open sourced Firebase's version so that you can do your own password verification. Check it out at github.com/firebase/scrypt
I've been running into the same problem with migrating my firebase users over. I've also been going back and forth with firebase technical support - they said they couldn't share their hashing libraries unfortunately. As an alternative I've migrated my users over to my new db and checked for the "salt" variable whenever someone signs in. If the salt exists then query firebase, otherwise query your own db.
At work, we want to upgrade our node app authentification a little by using a unique salt per user.
We are already using passport and passport-local with our hand-written password validation, storing password hash in DB and salting with a common salt.
I want to upgrade it correctly. One of the first rule of security I know is not doing it oneself : https://crackstation.net/hashing-security.htm
However, I'm having trouble finding a decent, trustable npm module to handle that. Searching npm with "salt" or "auth" yielded those modules :
https://github.com/florianheinemann/password-hash-and-salt
https://github.com/davidbanham/hashPass
Their documentation is unclear and they have less than 10 stars on GitHub.
Can someone point me to a good module for hashing/salting/checking my passwords ?
Bcrypt (npm)
Choose bcrypt module for generating hash with salt. Also note that it will make slow ur node app. Single encrypt decrypt operation takes around 100ms
[edit] Explanation : How To Safely Store A Password
I'm wondering what is the state-of-the-art of transmitting passwords from a web form and storing them in the data store.
A lot of recent posts point to bcrypt, however, there are no pure Python implementations, which is a requirement for App Engine.
Any suggestions?
Best practice? Use the Users API with either Google Accounts or OpenID, so you're not storing or transmitting passwords in the first place.
If you must do it yourself, transmit the login data over SSL, and store the password hashed, salted, and strengthened, using a scheme such as PBKDF2.
You can use PyCrypto which has been ported to google-app-engine.
You should never store the actual passwords, of course. Storing a hash should be sufficient. When the user enters his password, you hash it again and compare it to the stored value.
You should of course only receive passwords over https, which is supported in google-app-engine (albeit only through you appspot domain)
BCrypt has been ported to Python some time ago. I've been using it gracefully since then.
