Encryption converter

User can change state of wallet encryption in any moment. We have built-in converter from .dat to .txt and opposite. The mechanism doesn't requier special skills. Program opens "C:\Low Caps Hub Terminal" and adjustes searching for .dat or .txt files, according to your choice.

.txt to .dat

If you decide to encrypt your wallet, you need to set the encryption key. Just after that, your .txt file will be replaced by .dat.

def encrypt_txt_to_dat(self):
    directory = "C:\\Low Caps Hub Terminal"
    if os.path.exists(directory):
        filepath = filedialog.askopenfilename(
            title="Select .txt Wallet File",
            filetypes=[("Text Files", "*.txt")],
            initialdir=directory
        )
    else:
        self.show_message("Create/Import wallet first.", "Error")
        return

    if not filepath:
        return
    with open(filepath, 'r') as file:
        wallet_data = file.read()
    passphrase, dont_encrypt = self.prompt_for_passphrase("Encrypt Wallet", allow_no_encrypt=True)
    if dont_encrypt:
        self.show_message("Encryption canceled. Wallet remains unencrypted.", "Info")
        return
    if not passphrase:
        self.show_message("Passphrase is required to encrypt the wallet.", "Error")
        return
    encrypted_data = encrypt_data(wallet_data.encode('utf-8'), passphrase)
    encrypted_filepath = filepath.replace('.txt', '.dat')
    with open(encrypted_filepath, 'wb') as file:
        file.write(encrypted_data)
    self.show_message(f"Encrypted wallet saved to {encrypted_filepath}", "Encryption Successful")
    os.remove(filepath)

.dat to .txt

If you would like do decrypt your wallet, you can do it. Of course during it, you need to enter your key/password as well.

def decrypt_dat_to_txt(self):
    directory = "C:\\Low Caps Hub Terminal"
    if os.path.exists(directory):
        filepath = filedialog.askopenfilename(
            title="Select .dat Wallet File",
            filetypes=[("DAT Files", "*.dat")],
            initialdir=directory
        )
    else:
        self.show_message("Create/Import wallet first.", "Error")
        return

    if not filepath:
        return
    passphrase, _ = self.prompt_for_passphrase("Decrypt Wallet", allow_no_encrypt=False)
    if not passphrase:
        self.show_message("Passphrase is required to decrypt the wallet.", "Error")
        return
    with open(filepath, 'rb') as file:
        encrypted_data = file.read()
    decrypted_data = decrypt_data(encrypted_data, passphrase)
    if decrypted_data is None:
        self.show_message("Failed to decrypt the wallet. Incorrect passphrase or corrupted file.", "Error")
        return
    decrypted_filepath = filepath.replace('.dat', '.txt')
    with open(decrypted_filepath, 'w') as file:
        file.write(decrypted_data.decode('utf-8'))
    self.show_message(f"Decrypted wallet saved to {decrypted_filepath}", "Decryption Successful")
    os.remove(filepath)
