EOS Wallet Key Generator

Usage

Download eosjs-keygen.html from releases
Perform desired level of security
- Verify the code and build/release hash
- Use from cold storage

Here is one version of Cold Storage which I think is relatively simple given the tools available.

Get a USB with a read-only switch
Install a bootable OS like Ubuntu onto the USB
Remove the hard-drive (any storage device) and wireless card from an old laptop or desktop
Put the USB in read-only mode and boot
Connect to the Internet if desired, load any software or tools needed
Unplug the Internet (ethernet cable) and work with your software and private keys
Use a second writable USB for a backup
Power off

Never re-connect the Internet after working with private keys.

I'll make a post at Steemit.com with each release hash.

Additionally you can verify that the build hash matches the human source code:

git checkout tags/v1.0.0
npm install
npm run build

The build script runs sha256sum eosjs-keygen.html

You should see a sha256 hash and a eosjs-keygen.html file. For example, v1.0.0 should hash too:

3d87f79639fa3aceaadd217b40c9e07bd0ecedc889de64cd4334eac26f66076f  eosjs-keygen.html

This should match the release hash at github and the hash on Steemit.
