zeo-maker

Make signed Zeo items from a keypair and asset specification.

Installation

$ npm i -g zeo-maker

Usage

$ zeo-maker <assetName> <keysJsonFile> [-d <data>] [-s <skinImgFile>] [-q <quantity>]

How it works

1. Download your VRID's keys.json from my.zeovr.io
2. Use zeo-maker with your keys.json to generate the item you want. If the item is free you don't have to do anything else. If the item is secure your keys.json must be the keypair for the public key of the item, or else the item won't work if you try to load it.
3. Import your item to your VRID at my.zeovr.io

Example: wood

$ cat keys.json
{"privateKey":{"crv":"P-256","d":"BXHWuE1sHVHg1PlZLDqr7mrbD8AnFFXznCds2zJfL_0","ext":true,"key_ops":["sign"],"kty":"EC","x":"S_8irE80Ci5uSTm-tfo4hEuAuNYnzHdDUavcMam-eRg","y":"dVJq5kdkXuKfSoKC7oOcqNkWV2JfHybqd9AGrjuD_zU"},"publicKey":{"crv":"P-256","ext":true,"key_ops":["verify"],"kty":"EC","x":"S_8irE80Ci5uSTm-tfo4hEuAuNYnzHdDUavcMam-eRg","y":"dVJq5kdkXuKfSoKC7oOcqNkWV2JfHybqd9AGrjuD_zU"}}
