Password management and cryptography tool

Trident Password Manager (TPM)

We use a serverless database to store your passwords and then we secure them using Xor encryption.

---

Important instructions

1. Please note your pin and username after signup.
2. Do not share your pin / password with anyone.
3. Install all the required modules in requirments.txt for hasle free experience.
4. To run the program use main.py .
5. Have fun and give us your valuable feedback for improvement.

How this works?

1. Generating key and encrypting passwords

def makekey(self): 
    key =str(self.pin) + self.username 
    _key = Cryptograph.binthis(self,tri=key)
    return _key

We take two inputs from user that is username and pin then we join them and make a single string as shown in the above funtion.

def binthis(self,tri): 
    return "".join(f"{ord(i):08b}" for i in tri)

Character string of the key is then converted into a binary string using binthis() function

    def xorthese(self,password,key):
        result = ""
        password = Cryptograph.binthis(self,tri=password)
        if len(password) > len(key):
            lenfor0 = len(password) - len(key)
            key +='0'*lenfor0
            for i in range(len(key)):
                if key[i]==password[i]:
                    result += "0"
                else:
                    result += "1"
        elif len(password)<len(key):
            lenfor0 = len(key)-len(password)
            password += '0'*lenfor0
            for i in range(len(key)-1):
                if key[i]==password[i]:
                    result += "0"
                else:
                    result += "1"
        return result

Finally the password entered by user is encrypted using XOR encryption by xorthese()

2. Saving your passwords.

def createtable(self):
        self.cur.execute('CREATE TABLE "user" ("Sno" int PRIMARY KEY,"website_name" text,"username" text, "password" text)')

When user creates their account a database file is created for the user using createtable() from models class and after each successful save the passwords are written into the user table of database using intovalue() function of models class

    def intovalue(self,sno,websitename,_username,password):
        self.cur.execute(f'INSERT INTO "user" VALUES({sno},"{websitename}","{_username}","{password}")')
        self.conn.commit()

3. Master password

Username and pin are combined and converted into hash which is stored in the masterpassword table of database, this is later used for the authentication purposes.
