Answer 2: Hand written and encrypted files are a secure way to store important information. This type of file is typically used to store sensitive information such as passwords, financial information, or personal documents. The file is encrypted with a unique key, so that only the person with the key can access the file. To ensure the security of the file, it is important to store it in a safe place and to keep the key secure. Copying and pasting the file is not recommended as it can be intercepted or copied by someone else. Instead, it is best to download the .Tez keystore file as instructed, and store it in a secure location.
