cwt-lib (chain-web-token)

!npm

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.

#### syntax

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

#### arguments

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

privateKey: Private key or secret

usr: User name _Non-essential_

If you represent an individual, please use this parameter. Because it is required.
如果您代表个人，请使用此参数。因为它是必需的。

group: group name (enterprise name) _Non-essential_

If you represent a business (organization), please use this parameter. Because it is required.
如果您代表一家企业（组织），请使用此参数。因为它是必需的。

Note: One of the two parameters, usr and group, must exist, but not both.
注意：usr 和 group 两个参数中必须有一个存在，但不能同时存在。

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.
如果要为特定时间生成cwt，请不要忽略它，否则就是当前时间。

alg: Algorithm _Non-essential_

If the private key is ripple or jingtum chain, length is 64 and algorithm is ed25519, alg is ed25519.
如果私钥是ripple或者jingtum chain，长度为64，算法为ed25519，alg为ed25519。

#### Code Examples

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

// Representing an individual
const cwt = sign({
