I found a simple and understandable solution. We have Private Key, for example
ch74nhcwrf4439nfv340fvq3rvn23mf2fj20f204f
You can leave it on the computer + print and put somewhere at home + make another copy on the email.
It is necessary to do only one thing. Change 4-6 characters.
For example, change ch74nh to krw49d Further, it is enough to remember these 4-6 characters.
Now if a hacker gets access to your computer and finds a Private Key, he can not steal money.
I store the key on my computer and on e-mail, I worry that I will be stolen. I took and changed 4 symbols. I'm sure I will not forget them.
Thats a really bad idea.
Changing a few characters in a private key doesn't really add a lot of security.
You are basically betting on the possible 'attacker' not to try too hard.
Those human 'mind games' when 'securing' something with a 'hidden/special' approach is way less random than someone would believe.
You could simply encrypt the private key with a 4-6 long password. This would be a lot more secure than simply swapping them. Even though 4-6 characters aren't enough to be 'fully secured'.
If you (for whatever reason) plan to send/store your private key online, at least do yourself the favor to encrypt it properly with a passphrase which is long enough.
A lot of people seem to forget that email is broken as f*ck.
If you don't explicitely encrypt your data, you are an
easy target for any spoofing/interception of mails.
The author of the topic offers a method not for those who are engaged in encryption, etc.
This method is for those who in any case will not do this.
And already holds the private key open.
