cwt-lib (chain-web-token)

用于区块链身份认证的js库；
js library for blockchain identity authentication;

使用区块链的私钥对数据结构（{header: ... , payload: ...}）进行签名，生成cwt;
Using the private key data structure of the blockchain ({header:... , payload: ... }) sign and generate cwt;

使用区块链的公钥对cwt进行验证，证明其身份；
Verify the cwt using the blockchain's public key to prove its identity;

Synopsis

chain web token （缩写cwt) 是有三部分组成 header.payload.Signature,其中的 Signature 是对 header.payload进行签名。
chain web token (abbreviated cwt) is composed of three partsheader.payload.Signature, where Signature is the signature of header.payload.

目前支持ethereum、ripple、bitcoin、jingtum。
Currently support ethereum, ripple, bitcoin, jingtum.

API

sign

syntax

const sign = ({ chain: string; privateKey: string; usr: string; time?: number; alg?: string; })

arguments

chain: Support chain ('jingtum', 'ripple', 'ethereum', 'bitcoin')

privateKey: Private key or secret

usr: User name

time: Timestamp unit:s Non-essential

If you want to generate cwt for a specific time, please do not ignore it, otherwise is current time.

alg: Algorithm Non-essential

If the private key is ripple or jingtum chain, length is 64 and algorithm is ed25519, alg is ed25519.

Code Examples

import { sign } from "@jccdex/cwt-lib";
// const sign = require("@jccdex/cwt-lib").sign

const cwt = sign({
  chain: "",
  privateKey: "",
  usr: ""
});
