Issue with python password encryption

so i am trying to create a user using python directly entering a user enter into db but on that my auth fails

salt = bcrypt.gensalt(10)
hashed_password = bcrypt.hashpw(password.encode('utf-8'), salt)
user_id = uuid.uuid4()
cursor.execute('''INSERT INTO users (id, name, email, password, salt, isAdmin, isOwner)VALUES (?, ?, ?, ?, ?, ?, ?)''',(user_id, username, None, hashed_password, salt, True, True))

salt = bcrypt.gensalt(10)
hashed_password = bcrypt.hashpw(password.encode('utf-8'), salt)
user_id = uuid.uuid4()
cursor.execute('''INSERT INTO users (id, name, email, password, salt, isAdmin, isOwner)VALUES (?, ?, ?, ?, ?, ?, ?)''',(user_id, username, None, hashed_password, salt, True, True))

This how my code looks like is not possible to hash password via python i think hashing is correct but docker logs show no error what reason of fail auth hope you can point me to right direction. 🙂

Can I install Homarr on a Raspberry Pi?

Hi, we do not provide support for your own code. Have you considered to use the Homarr API?

Gojo•8mo ago

Where can i find docs for that? I mean homarr API and i just wanted to confirm that encryption is correct or not ?😅 If you can point to homarr API docs that would be great too 🙂

Manicraft1001•8mo ago

You can find the docs in the management pages of your app @Gojo Under "tools"

Thank you i will look into it 😄 is there a way to check why auth is failing some logs or something ?

Manicraft1001•8mo ago

Authentication failures will result in 401 or 403 on the API and a log message Can I mark this as resolved?

Gojo•8mo ago

yeah sure 🙂 Thank you for your help :d I have a question so basically i want to create a admin user without interacting with UI so what i am doing is using python to create a admin user directly in DB in user table and i checked encryption is correct from online tools that password is encrypting correctly but still i can't login is there a way to create first time admin user without interacting through UI?

Manicraft1001•8mo ago

Using the API @Gojo

Gojo•8mo ago

But for that i need auth token right? And db don't have a auth token until user is created if i am not mistaken please correct me if i am wrong and sorry for all the trouble

Manicraft1001•8mo ago

Yes, correct Have you tried restarting Homarr after you edit the dB?

Gojo•8mo ago

Yes still no luck :/

Manicraft1001•8mo ago

Does it actually write to the DB?

Gojo•8mo ago

Yes checked db manually If u want i can show u the entries

Manicraft1001•8mo ago

Yes please do Also, does the library you use work the same? It must encrypt the same way for this to work

Gojo•8mo ago

I checked using online bycrypt tools so encryption is corrected and after good its almost same

Manicraft1001•8mo ago

"almost" is not the same lol So your code is incorrect. Hence Homarr is unable to compare the hashes.

this is my entry in db

Manicraft1001•8mo ago

Yes, looks good but I cannot know whether the hash is fine or not from looking at it. You said that it's different than when you build it using Homarr? How did you test that? It should be quite clear that if the hash is different, login will refuse to work.

Gojo•8mo ago

Online bycrypt tool

Manicraft1001•8mo ago

Yes but how? What do you encrypt? How do you compare? What salt are you using?

Gojo•8mo ago

So that tool allow u to check bycrypted hash with orginam string if they are same they return a 200

Manicraft1001•8mo ago

Let me ask you again:

Yes but how? What do you encrypt? How do you compare? What salt are you using?

Yes but how? What do you encrypt? How do you compare? What salt are you using?

I am volunteering to help you. Please help me by providing information. You did not answer my questions. I am unable to help you debug when you don't answer them Do you simply not know how this "online checker" handles encryption? Then please say that

Gojo•8mo ago

No i am not sure how they does Sorry its online site so i am aware how they check it

Manicraft1001•8mo ago

It's important to understand such things when programming. We do the encryption like this: https://github.com/ajnart/homarr/blob/1cc4ae5c03b2829f9eb0fa032330a460e2de6587/src/server/api/routers/user.ts#L434 I suggest you to use a bcrypt library and attempt to do the same. - Generate a salt with 10 rounds - Hash the cleartext password using said salt - Store both in the database - Restart Homarr
