Hey Dear,How are you?.Today I am little bit sad I am not able to log in into my Account Pakakistani-BCH-Lover without Email.No doubt,ups and downs are part of life.Thanks @Ellie for your appreciation.I dedicate my next part to you hope so you Guys like it.Sooner or later,I shall upload my innovation on my YouTube Chanel,"Online Earning with zero Investment".Now let us take a start of Part 2.And its 3rd and final part should be uploaded soon.I can't wait for my account recovery for this awesome article and new innovation in the world.

To make things a little more official, I went the extra mile of encrypting the text file that held the wallet's private key using my PGP signature. This  guarantees funds can only be transferred out of the wallet if it's plugged into my computer, where the keys are stored. For extra comfort, the encrypted file gets stored on a microSD card -- one that could be removed or copied, and which can be physically locked in a more secure location if need be.

I got to be a little more carefree with the public key. As far as displaying the key as a basic code, I simply uploaded and renamed one of my songs on the player. "None Shall Pass" by Aesop Rock seemed like the most obvious candidate. To get it displayed on the front of the SanDisk, I took its QR code and made it the album art for the song on the player, thus allowing for easier transactions or verification of balances.

This approach came with a couple of perks. While it's a little harder (although not impossible) to make a universal wallet that holds multiple currencies, it's still possible to import and export wallets of different currencies by adding public key title songs and private key encrypted text documents. I even came across a couple of accidental -- and most certainly useless --security features. For example, Monero addresses are a minimum of ninety-five characters long. This means that the entire public key cannot ever be visible on the display at any one moment. Instead, the auto-scroller for music titles shows one part of the address at a time, preventing outsiders from photographing a public key.

Mind you, this isn't a terribly fancy approach for making hardware wallets. The state of my mp3 player is only a little more sophisticated than a paper wallet. But it's important to remember that a paper wallet is still a wallet. As the person responsible for the private keys, you are the sole representative for the funds held in your wallet. And with keys held in a digital format, it's not an unimaginable prospect to create a program that conveniently reads the titles of songs or decrypts text documents with a users PGP key when a you submit a password -- thus, acting as a user-generated interface to make the more nuanced features of a software wallet possible.

These are obviously not complicated devices -- It doesn't take an iphone or a tablet to make a cryptocurrency wallet. And it shouldn't require it, either. Rather, I think the single most significant aspect of this format is that any such device complies with the air gap. No device that stores our hypothetical wallet is in any way shape or form capable of independently connecting to an unsecured network. There are no sim chips. There are no radio antennas. Everything that can be put into airplane mode is in airplane mode by default. In some cases, there's not even any firmware present to support a sim chip -- the discarded flip phones are just too old for their networks anymore.

These are all,in the strictest sense of the word,hardware wallets

I'd like to turn your attention to the USB stick on the far right. This here is by far the most ridiculously straightforward example of a secure, low cost, do-it-yourself hardware wallet. Loaded onto it is a copy of TailsOS, downloaded from another drive and verified through a PGP signature. TailsOS is an open source Linux distro that brings many unique security features to the table, including amnesic file storage -- any information you play with while running the OS is wiped entirely, even from the RAM, after shutdown. The sole exception to this is rule is the optional persistent file storage. This storage is password encrypted on the local drive -- or another external drive, if you want -- rendering permanent file storage inaccessible to adversaries.

And perhaps best of all, it comes with a pre-installed Electrum wallet, with your keys saved in persistent storage.

This was all about today.Happy Friday to you all.God bless you.Thanks reader for your patience.
