jwt-lib

A cryptocurrency-compliant js library 一个实现符合加密货币的js库

Based on jsontokens library (https://github.com/stacks-network/jsontokens-js). 基于jsontokens库进行扩展。

INSTALL

npm install @maincc/jwt-lib

Documentation

example import

import WalletJwt from "@maincc/jwt-lib";

• If you don't have an Ethereum account, you can generate it through generate.
  如果你并没有以太坊的账户，可以通过generate生成。

  example generate

  const wallet = WalletJwt.generate();

  result

  {
    privateKey: '0xc5b893aef8c2e847dc14ddadb7dfd3be5781b7a5a46e0cbcc00bfa992c626ddc',
    publicKey: '0x6f592757f8e6506a5f950df6fcbb6b8000b3ef00c24cc69dfdb3155d322b182c4d31216ae1154b63211c8970977ccb2a72272ac0cce8004e0c26c86dfc01046a',
    compressPubKey: '026f592757f8e6506a5f950df6fcbb6b8000b3ef00c24cc69dfdb3155d322b182c',
    address: '0x50692568f1184911ecbfa2de4147fecba5b0b386'
  }

• If you have an Ethereum account and have its public and private keys. Then you can perform jwt related operations.
  如果你拥有了以太坊的账户，并掌握其公私钥。那么可以进行jwt的相关操作。

  • example sign

  const data = {
    header:{
      type: 'CWT',
      chain: 'ethereum'
    },
    payload:{
      sub: '1234567890',
      name: 'John Doe',
    }
  };
  const jwt = WalletJwt.sign(data, wallet.privateKey);

  result

  eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NksiLCJ0eXBlIjoiQ1dUIiwiY2hhaW4iOiJldGhlcmV1bSJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIn0.5ZICOX22jNPVeewb3o0fsMSJM04CQnO5aIbZaW_vfakwYUReR2-mZEiDkz-ezdmkOH6xKObnZDpMcNCnv9n-Rw

  The signature must contain payload and header fields.

  签名的内容必须带有payload和header字段。

  • example decode

  WalletJwt.decode(jwt)

  result

  {
    header: { typ: 'JWT', alg: 'ES256K', type: 'CWT', chain: 'ethereum' },
    payload: { sub: '1234567890', name: 'John Doe' },
    signature: '5ZICOX22jNPVeewb3o0fsMSJM04CQnO5aIbZaW_vfakwYUReR2-mZEiDkz-ezdmkOH6xKObnZDpMcNCnv9n-Rw'
  }

  • example verify

  WalletJwt.verify(jwt, wallet.publicKey) or WalletJwt.verify(jwt, wallet.compressPubKey)

  result

  true

• If you need public and private keys in pem format, or Signature in jwt is ASN.1 DER format.
  如果你需要pem格式的公私钥,或者需要jwt里的Signature是ASN.1 DER格式。

• example privToPem

WalletJwt.privToPem(wallet.privateKey)

Convert the private key to pem format. Note: The resulting pem is SEC1 specification.
将私钥转换成pem格式，注：生成的是SEC1规范的pem。

**`result`**  

-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMW4k674wuhH3BTdrbff075XgbelpG4MvMAL+pksYm3coAcGBSuBBAAK

iXCXfMsqcicqwMzoAE4MJsht/AEEag==
-----END EC PRIVATE KEY-----

• example pubToPem

WalletJwt.pubToPem(wallet.publicKey)

Convert the public key to pem format. Note: The parameter must be an uncompressed public key.
将公钥转换成pem格式，注：参数必须是未压缩的公钥。

**`result`**  

-----BEGIN PUBLIC KEY-----
MFYwEAYHKoZIzj0CAQYFK4EEAAoDQgAEb1knV/jmUGpflQ32/LtrgACz7wDCTMad
/bMVXTIrGCxNMSFq4RVLYyEciXCXfMsqcicqwMzoAE4MJsht/AEEag==
-----END PUBLIC KEY-----

• example sign(... , 'der') && verify(... , 'der')

const jwtDer = WalletJwt.sign(data, wallet.privateKey, 'der');
WalletJwt.verify(jwtDer, wallet.publicKey, 'der');

Generate jwt in ASN.1 DER format (to meet openssl and other cryptographic libraries) and verify.
生成符合ASN.1 DER格式的jwt（满足openssl等密码库）并验证。
