Of course, you will need to install nodejs, npm, git, curl etc, I am not gonna cover these in this article\n\nMethod 1: Use eosjs-ecc tool from https://github.com/EOSIO/eosjs-ecc\na. The wiki already has the installation steps:\ngit clone https://github.com/EOSIO/eosjs-ecc.git\ncd eosjs-ecc\nnpm install\nnpm run build_browser\n\nb. To generate private/public keys, create a html file under eosjs-ecc/dist folder with content\n```\n<!DOCTYPE html>\n<html>\n<head>\n<script src=eosjs-ecc.js></script>\n</head>\n\n<body>\n<script>\nvar ecc = eosjs_ecc\necc.randomKey().then(privateKey => {\n    document.write('Private key:      ')\n    document.write(privateKey)\n    document.write(\"<p>\")\n    document.write('Public key:       ')\n    var pubkey = ecc.privateToPublic(privateKey)\n    document.write(pubkey)\n})\n\n</script>\n\n</body>\n</html>\n```\nand open html file so that I will show a pair of keys\n\n2) To validate private/public keys, create another html file under eosjs-ecc/dist folder with content\n```\n<!DOCTYPE html>\n<html>\n<head>\n<script src=eosjs-ecc.js></script>\n</head>\n\n<body>\n<script>\nvar ecc = eosjs_ecc\nvar privateWif = 'Your EOS private key' \nvar pubkey = ecc.privateToPublic(privateWif)\ndocument.write(pubkey)\ndocument.write(\"<p>\")\ndocument.write(privateWif)\nvar expected_pub = 'Your EOS public key'\nif (pubkey === expected_pub) {\n  document.write('<p>match')\n} else {\n  document.write('<p>not match, expected:')\n  document.write(expected_pub)\n}\n</script>\n\n</body>\n</html>\n```\n\nMethod 2:  Use EOS key utility tool in genesis https://github.com/EOSIO/genesis/tree/master/tools/keys\n\na) for installation, use method 2 in the wiki not method 1\nnpm install -g electron-packager\nnpm run compile\n\nb) to run it, you can go to tools/keys/build/EOSXXXXXXXXX/EOSXXXXXX\nXXX is the file name I can't remember but there is an executable file that just run it, it will show an app\nClick generator to generate keys\nand Click Validator to validate keys\n\n\nMethod 3:  Use scatter\nScatter is a tool that provides a google chrome exention https://scatter-eos.com/\ninstall the extension and then after you create your account in scatter, click settings button on top right\nand you can see Key Pairs button, click it and you can generate or validate on the UI, it will even tell you if your public key\nor private either is not valid or do not match\n![scatter.PNG](https://steemitimages.com/DQmfMo5gGsRZVfWWJNUuoeRzJ1ShHNcaygebshrMyh4CLFE/scatter.PNG)\n\n![scatter1.PNG](https://steemitimages.com/DQmYMpDZm7RRcbxrBKpTjXBjk1Bv5EMGwGacWo6J6xxTs4w/scatter1.PNG)\n\nGiven above, what I did was\n1) Create a virtual machine using Virtualbox\n2) Install Ubuntu 18.04\n3) Clone all github source code online and follow the steps to set them up\n4) Install scatter\n5) Disconnect the network\n6) Use the Method 1 to generate private/public key\n7) Validate the my private and public key using method 2 and 3 to garantee (so paranoid lol)",
