BITNATION ID

ID generator for the BITNATION project.

After generating a BITNATION-ID the userData will be signed and that signature together with the public key will be saved as a transaction on Horizon. The format will be signature:publicKey. The transaction id will be saved as hztx in your ID.

You will be able to save your ID as a JSON file that will have the following structure (without the indentation and spacing):

{
	"userData": {
		"name": "Ed Sheeran",
		"height": 168,
		"dob": 19801111,
		"witness1": "Bob Dole",
		"witness2": "Jane Simmons"
	},
	"image": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==",
	"hztx": "87buyhjksadfbiu7t23njdsf",
	"crypto": {
		"publicKey": "87yboiuahdfniauns98u98",
		"encryptedSecretKey": "khjabsdf8o7ybo283niouhf98noljkl",
		"salt":"sfdf2322d",
		"nonce": "09iniouhnis6tb",
		"logN": 16,
		"blockSize": 8
	}
}

Using scrypt to derive a key from the password entered, and then using that key to encrypt the secret key.

The ID is now downloadable as a JSON file.
