account.UpdatePasswordSettings INPUT_FETCH_ERROR

[1pyxa1]

Hi there!
Trying to use functions.account.UpdatePasswordSettings with an empty current password and have an error

pyrogram.api.errors.error.UnknownError: [520 Unknown error]: {
    "_": "types.RpcError",
    "error_code": 400,
    "error_message": "INPUT_FETCH_ERROR"
}

here is my function:

def update_password_settings(client, new_password, current_password=None, email=None):                                           
      r = client.send(functions.account.GetPassword())                                                                             
      if current_password:                                                            
          current_password = r.current_salt + current_password.encode() + \           
              r.current_salt                                                          
          current_password_hash = sha256(current_password).digest()                   
      else:                                                                           
        current_password_hash = bytearray()                                         
      new_password = r.new_salt + new_password.encode('utf-8') + r.new_salt           
      new_password_hash = sha256(new_password).digest()                               
      if email:                                                                       
          new_settings = types.account.PasswordInputSettings(                         
              new_salt=r.new_salt,                                                    
              new_password_hash=new_password_hash,                                    
              email=email)                                                            
      else:                                                                           
          new_settings = types.account.PasswordInputSettings(                         
              new_salt=r.new_salt,                                                    
              new_password_hash=new_password_hash)                                    
      client.send(functions.account.UpdatePasswordSettings(
           current_password_hash, new_settings=new_settings))

Would be grateful for any advice!

@1pyxa1 What are you trying to do exactly? Remove the password? Change it? ...?

[1pyxa1]

@delivrance Trying to set new password first time.

[1pyxa1]

I found the solution. Tested it for setting new password first time and for changing it. Works great.
Here is my version:

def update_password_settings(client,                                                
                             new_password,                                          
                             current_password=None,                                 
                             email=None,                                            
                             hint='hint'):                                          
    r = client.send(functions.account.GetPassword())                                
    salt_random = os.urandom(8)                                                     
    salt = r.new_salt + salt_random                                                 
    if current_password:                                                            
        current_password = r.current_salt + current_password.encode() + \           
            r.current_salt                                                          
        current_password_hash = sha256(current_password).digest()                   
    else:                                                                           
        current_password_hash = salt                                                
    new_password = salt + new_password.encode('utf-8') + salt                       
    new_password_hash = sha256(new_password).digest()                               
    if email:                                                                       
        new_settings = types.account.PasswordInputSettings(                         
            new_salt=salt,                                                          
            new_password_hash=new_password_hash,                                    
            email=email,                                                            
            hint=hint)                                                              
    else:                                                                           
        new_settings = types.account.PasswordInputSettings(                         
            new_salt=salt,                                                          
            new_password_hash=new_password_hash,                                    
            hint=hint)                                                              
                                                                                 
    return client.send(functions.account.UpdatePasswordSettings(                        
        current_password_hash, new_settings=new_settings))    

Maybe it would be useful to add it to pyrogram/client/client.py for other users, what do you think?

Maybe it would be useful to add it to pyrogram/client/client.py for other users, what do you think?

Definitely! Being a pretty young project there's a lot to be added and suggestions are very welcome.

I was thinking about adding three different methods to create, change and remove the password, or maybe a single one that does everything? What do you think?

[1pyxa1]

Personally I would prefer a single one that does everything. Maybe put there little more explanation. Because the code for three different methods will be pretty much the same. But of course it's up to you. And i think it's not so important which way to choose.

Here is my final tested version with removing a password also:

def update_password_settings(client,                                             
                             new_password=None,                                  
                             current_password=None,                              
                             email=None,                                         
                             hint='hint'):                                       
                                                                                 
    if new_password is None and current_password is None:                        
        logging.warning("new_password is None and current_password is None.\     
                        Nothing to do.")                                         
        return False                                                             
                                                                                 
    r = client.send(functions.account.GetPassword())                             
    salt_random = os.urandom(8)                                                  
    salt = r.new_salt + salt_random                                              
                                                                                 
    if current_password:

I've opted for three distinct methods, I think it's simpler to use this way: 8cc0fe1
