``shell`
npm install @maincc/jwt-lib
example import
`js`
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
`js`
const wallet = WalletJwt.generate();
result
`js`
{
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
`js`
const data = {
header:{
type: 'CWT',
chain: 'ethereum'
},
payload:{
sub: '1234567890',
name: 'John Doe',
}
};
const jwt = WalletJwt.sign(data, wallet.privateKey);
result
`js`

The signature must contain payload and header fields.
签名的内容必须带有payload和header字段。
- decode`
js`
WalletJwt.decode(jwt)
result
`js`
{
header: { typ: 'JWT', alg: 'ES256K', type: 'CWT', chain: 'ethereum' },
payload: { sub: '1234567890', name: 'John Doe' },
signature: '5ZICOX22jNPVeewb3o0fsMSJM04CQnO5aIbZaW_vfakwYUReR2-mZEiDkz-ezdmkOH6xKObnZDpMcNCnv9n-Rw'
}
- verify `
js`
WalletJwt.verify(jwt, wallet.publicKey) or WalletJwt.verify(jwt, wallet.compressPubKey)
js`
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
`js`
WalletJwt.privToPem(wallet.privateKey)
result
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。
`
js`
-----BEGIN EC PRIVATE KEY-----

iXCXfMsqcicqwMzoAE4MJsht/AEEag==
-----END EC PRIVATE KEY-----
- pubToPem `
js`
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。
`
js`
-----BEGIN PUBLIC KEY-----
MFYwEAYHKoZIzj0CAQYFK4EEAAoDQgAEb1knV/jmUGpflQ32/LtrgACz7wDCTMad
/bMVXTIrGCxNMSFq4RVLYyEciXCXfMsqcicqwMzoAE4MJsht/AEEag==
-----END PUBLIC KEY-----
- sign(... , 'der') && verify(... , 'der') `
js`
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。
