Hello.
If I'm not wrong...
There are manufacturers of non-electronic cold cryptographic wallets, for example
https://www.balletcrypto.com, to which you can commission them to manufacture them with the data you give them.
The procedure is the next:
1.- You create a secure password.
2.- With the password, you create an intermediate code (
https://www.balletcrypto.org/#/bip38-intermediate-code) and send it to the manufacturer. Only the intermediate code, (NO PASSWORD).
3.- With the intermediate code, the manufacturer creates your cold wallet card that contains: A private key BIP38 (decryptable with your password), the Bitcoin address and a confirmation code with which you can verify, with your password, that the card's Bitcoin address really depends on your password. (

My question: Can the private key BIP38 be known with the confirmation code?
A greeting.
