Wow its amazing please make a video for gui password manager
I'm getting an error at line 25 it says unresolved attribute reference 'add_password' for class 'PasswordManager' edit: I found out that tabnine typed 'add_password_file' instead of 'add_password'
Great video, but I have one question, isn't that password manager vulnerable? I mean anyone with access to the .key and the .password files will be able to simply decrypt and read the password right? or maybe i'm missing something here ..
turn it into .exe by comping all the files. all files will be hidden and turned into one
@@Bl0xxy that would make the program use the same key for any user...
@@jeka1030 but what if you use a randomizer for first launch?
You're right. You want to use hashing instead if you want to make this secure
You must secure the code/key/password files too.
Wooow, so good video with even great explantion. Thank you so much neural nine.
and there bug.
create key
create file. need add password before file saved?
and when files are loaded
create key
create file
all sites and password + default ones go new file so you have duplicates
def create_password_file(self,path, initial_values=None):
self.password_dict = {} #fix same when load file
also pimped to have default.key default.file on start if not exist it create it with default values. so we are quickly business xD
added list sites so not need quess when there no error check
also added remove site and change password. now its kinda manager with when load key its print keys on folder also on file
quickly ca choose without write name
Great Video! When I decode the passwords I'm getting " b' " preceding the password so I had to import codecs and then wrap the decode statement into codecs.decode(Fernet(self.key).decrypt(encrypted.encode()) in order to eliminate the prefix. This converted the passwords to string instead of byte type
good practical programming,but nothing todo managing. managing is notepad then encrypt file
this not even change password or site and not delete
and key should be protected by password otherwise anyone who launch script can manage even there nothing to manage just add
I don't get this.. So in this program I have to literally write all my passwords into the script in the dictionary? How is that safe, and all the encryption and decryption and stuff seems pointless to me then.. I don't get it, why not just have a textfile with all the sites and passwords? What does this do? I feel dumb
I completed everything, but now I am stuck with a NameError when I do #5 in the cli it says that name 'password' is not deefined. Any help? I can post the code if need be.
Somewhere in your code it says password = … well there’s your error in there. Probably tells you what line also
Nice tutorial for a simple passwort manager but for the real world its not worth using bc can easily be hacked
Hi, great video..but Im getting an error for whenever i load the password file. This is what it looks like:
Enter your choice: 4
Enter path: pass.pass
Traceback (most recent call last):
File "/Users/---/Documents/vsc_projs/practice.py", line 99, in
main()
File "/Users/---/Documents/vsc_projs/practice.py", line 83, in main
pm.load_password_file(path)
File "/Users/---/Documents/vsc_projs/practice.py", line 32, in load_password_file
site, encrypted = line.split(":")
TypeError: a bytes-like object is required, not 'str'
This is the code for that part:
def load_password_file(self, path):
self.password_file = path
with open(path, 'rb') as f:
for line in f:
site, encrypted = line.split(":")
self.password_dict[site] = Fernet(self.key).decrypt(encrypted.encode()).decode()
I was hoping you could help tell me what I did wrong.
with open(path, 'rb') as f: ---> with open(path, 'r') as f:
encode it first
When running choice 3 I get this error:
"Traceback (most recent call last):
File: . . . line 99, in
main()
File: . . .line 80, in main pm.create_password_file(path, password)
File: . . .line 25, in create_password_file self.add_password(key, value)
File: . . .line 36, in add_password
self.password_dict[site] = password
^^^^^^^^^^^^^^^^^^
AttributeError: 'PasswordManager' object has no attribute 'password_dict'. Did you mean: 'password_file'? "
I re-watched the video, looking for errors on my part, but couldn't find any. Could this be that I am missing a plugin or am overlooking something? Let me know what you all think. Thanks
I fixed the bug!
What is the most reliable python cryptography module or modules?
how would u implement it so that key is derived each time form the passphrase? generating same key for the same passphrase each time
When you entered if __name__ == "__main__":
main() I get main is not defined. what am I missing?
Figured it out had wrong ident spacing
@Jay716, i get the same problem. Please help me to fix it. I don't understand what you mean to fix yours.
@@fulbertkoffi5640 make sure that if __name__ == "__main__":
main() is outside of the if statement hope that helps.
Write like this
If __name__ == "__main__" :
Main()
You missed underscore
great!
When I try to print the key like u did at 4:58, it gibes me the error message : 'PasswordManager' object has no attribute 'create_key'. Any ideas?
Having the same problem. Trying to slove it now.
Hello thank you….how can I add hashing?
Wich video did you do the "__main__" thing that is mentioned?
Seems that so much of programming requires constant Internet access these days. Is there any advice you can give on coding when given very limited or perhaps even non-existent inet access?
(In my case it's limited by the fact I have to use my cellphone for all my inet.)
Take care of yourself. Your health is far more important than educating my dumb a... ... self.
Hope you feel better soon! ❤️
if using python 3.10.x I think hashlib and crypt are part of the standard python library, so no need to import an external like cryptography; both hashlib and crypt have been in python since 3.6.x; i don't know how yet to use them but they are referenced in some UA-cam videos
@@techgoat618 How does that help reduce the need for inet access? Wrong thread? jus askin..
@@thomasgoodwin2648 there was a reference to use of a cell phone for internet access, if coding in Python the presumption is python is loaded locally already, pip'ing external modules then is reliance on the net, so a local library that is native to Python already installed wont need internet access to retrieve it. So browse the net on the cell, for research, but then you'd need to hot-spot the cell phone and connect the laptop to download, i.e. 'pip install...' jus sayin
@@techgoat618 Ok. Gotcha. Actually I am tethering on my cell now. Problem is, even the 'unlimited' plans seem to come with a lot of limitations that amount to caps.
I appreciate your response and though it it doesn't apply directly in my case, perhaps it will help someone else in a different but similar situation.
Good lookin' out! 👍
the main at the bottum line is having a problem
Good job
Amazing brother
🤩! Awesome! Please create a video to create a mobile app and connect to any Python program to work on backend!
mine says could not be resolved from source
you don't like virtualenv?
Hi, i'm facing a really odd issue, for some reason, even though i have testkey.key in my folder with my password.py file, when i press option 2 and then type testkey.key, it says no such file or directory found, even though the file is right there, why is this so? thank you
nevermind, i figured out i have to direct it to the specific folder it's in first, despite it all being in the same folder...weird, so for me its not just "testkey.key" but "Project\testkey.key", and same applied to mypassword.pass
@@austinnunez2031 hey bro i have same problem what did you do?
@@kishankushwaha4933 Specify the directory of the "testkey.key" file, e.g "Testproject\testkey.key" and if that won't work use the full directory of the file
Could I add 2fa onto this ?
time stamps to myself: 0:25
does anyone know what style guide he uses when coding?
PEP 8 i guess..

pretty cool
Great video! learned a lot
Hello! thank you a lot for this. Very good job. But i get this error when i try it :
NameError: name 'main' is not defined. Did you mean: 'min'?
Please help to fix
IS OK for now! tks
please do a recorder video but python no import only python vanilla please
Thank you! this is not so difficult for me.
In my opinion, this video is unuseful. Why? Password manager MUST BE comfortable. When I open steam, email, VPN and another app then my password manager must automatically fill text fields to replace my routine. Here is simple app which write and read text from file + encrypt and decrypt text by ready python module + simple menu based on if statements.. why not match (pythonic switch)?
I found NeuralNine's password manager very "comfortable" because it educated me about how to create a functional password manager; plus the use case appears to be oriented toward the command line rather than an app that auto-fills password in your gaming app or wherever. I have and use LastPass and other apps for my auto-fill needs, but with respect to learning python NeuralNine''s example was well presented, IMHO
are you really too lazy to copy and paste a password?
@@multiarray2320 where is the fun in that? my goals include learning how to write code in Python that allows me to use hand-crafted CLI tools. All the apps I already have all have saved passwords, and browsers have saved passwords, so i would really only ever cut and paste once. I *could* do it that way, but it defeats my purposes, of learning... there is an elegance to crafting an app for the command line that accesses credentials stored securely in a file, rather than the throw-back neo-caveman way of cutting and pasting...IMHO
@@techgoat618 same here, it's not that i cant remember my passwords, its more like i want to learn how to do encryption and file managing from a close to practical standpoint
