Lol. That eth acc address. Lol.

Anyway, for those reading this comment, normally we need to copy paste crypto private key to a text or word file. Which mean we need to secure that file.

One of the easiest, and quite effective way...

to secure that file is to password-compress it using "AES256" algo from 7-zip or WinRAR software. When compressing, choose "advanced" mode, put the password and select aes256. Don't use winzip because it doesn't support aes256.

It's free and easy to do. It doesn't give perfect protection, but adequate protection. Then the file can be put on flash drive (and lock it in safe deposit box :D ), or if you dare to do it, on cloud storage (only for emergency please. Don't put password on public cloud).
