7zip use AES256 which is very safe.
I first encrypt the wallet within Electrum with a long password, and then use 7zip to encrypt the wallet file with a different long password.
I keep the encrypted file in my offline laptop and an USB as backup.
But when I use 7zip to encrypt the wallet file, I only need to type the password once. After that, everytime I open my file I don't need to type the password. I want to make sure that everytime I open the file, I need to type the password.
Also, when you open electrum, it loads the wallet file instantly right? So how do you encrypt it with a long password? I just have one password for it and no encryption.
Not sure what you mean by that. Every time you want to open/extract the .7z file you need to type the password.
Yup you don't need to type the password to open electrum and see the balance and addresses, but you need to type the password to spend the bitcoin or see the private keys. So, your bitcoin is still safe if someone has your wallet file only but not your password.
So thats how it is! Thanks for your explanation, I appreciate it.
So there is no point in backing up the wallet file right? Only keeping the seed safe on some papers would do the work just perfectly fine, right?
Also, can I prevent someone from opening the folder, where the electrum wallet is and the wallet file? Like I said when I used 7zip to encrypt it, I needed to only type the password once. But you say that it is every time, for me its not. I just right click on the folder, and choose the Add to archie optio. Then I get a zip file, and when I open my wallet, I have to type the password. So yeah it's correct until here. But my wallet is also in the folder. And I want to have passowrd protection each time before the folder opens, wether its in the zipfile or not. Just to protect the wallet file. Is this possible?
I think on windows you have the option to create a briefcase or passwordprotect a file folder.
