JWT

verify

JOSE ref

Additional options

name	Description
kid	Using specific key in JWKS
jti	Verify payload jti

// `key` must be JWK or JWKS.
await JWT.verify(token, key, options);
// Use embedded key instead given one.
await JWT.verify(token, undefined, options);

sign

• JOSE ref

Using JOSE options

name	Referrer
issuer	setIssuer
audience	setAudience
subject	setSubject
exp	setExpirationTime
jti	setJti
notBefore	setNotBefore
iat	setIssuedAt
typ	Header
kid	Header
alg	Header

Additional options

name	type	default	description
jwk	boolean	false	Whether embedded key to header

await JWT.sign(payload, key, options); // key must be JWK or JWKS

decrypt

JOSE ref

Additional options

name	Description
kid	Using specific key in JWKS
enc	Encrypt algorithm
alg	Key management algorithm

await JWT.decrypt(cypher, key, options);

encrypt

JOSE ref

Using JOSE options

name	Referrer
issuer	setIssuer
audience	setAudience
subject	setSubject
exp	setExpirationTime
jti	setJti
notBefore	setNotBefore
iat	setIssuedAt
typ	Header
kid	Header
enc	Header
alg	Header

await JWT.encrypt(payload, key, options);

JWS

You can sign pure string.

verify

JOSE ref

await JWS.verify(data, key, options);

sign

JOSE ref

Only using below JWT.sign's options:

• typ
• kid
• alg
• jwk

await JWS.sign('some-data', key, options);

JWE

You can encrypt pure string.

decrypt

JOSE ref

Additional options

Same as JWT.decrypt

await JWE.decrypt(cypher, key, options);

encrypt

JOSE ref

Only using below JWT.encrypt's options:

• kid
• alg
• enc

await JWE.encrypt('some-data', key, options);

JWK

JOSE ref

// generate key
const key: JWK = await JWK.generate('ES256', {
  kid: 'some-id',
  use: 'sig',
  // crv: string, some algorithms need to add curve - EdDSA
  // modulusLength: number, some algorithms need to add length - RSA
});

// object to JWK
const key: JWK = await JWK.fromObject({
  kid: 'some-id',
  alg: 'ES256',
  kty: 'EC',
  crv: 'P-256',
  x: '123',
  y: '456',
  d: '789',
});

// JWK to object
const keyObject: JWKObject = key.toObject(false); // true to output private object, default: false

// private JWK to public JWK
const newKey: JWK = await key.toPublic();

// get key's status
key.isPrivate;

// check key "id", "use", "alg"
try {
  // return `this` if all pass
  key.getKey({ kid: 'some-id', use: 'sig', alg: 'ES256' });
} catch (err) {
  // throw error if this key has different metadata from options
}

JWKS

// object to JWKS
const keys = await JWKS.fromObject({
  keys: [
    {
      alg: 'ES256',
      kty: 'EC',
      x: '123',
      y: '456',
    },
  ],
});

// get key from store in specific options
try {
  const key: JWK = keys.getKey({ kid: 'some-id', use: 'sig', alg: 'ES256' });
} catch (err) {
  // throw error if not found
}
const key: JWK = keys.getKeyByKid('some-id');
const key: JWK = keys.getKeyByUse('sig');
const key: JWK = keys.getKeyByAlg('ES256');
const publicKeys = await keys.toPublic();
