If you find the module useful, please consider supporting the project by [becoming a sponsor](https://github.com/sponsors/panva). ## Call Signature ▸ **compactVerify**(`jws`, `key`, `options?`): [`Promise`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\<[`CompactVerifyResult`](../../../../types/interfaces/CompactVerifyResult.md)\> Verifies the signature and format of and afterwards decodes the Compact JWS. This function is exported (as a named export) from the main `'jose'` module entry point as well as from its subpath export `'jose/jws/compact/verify'`. ### Parameters | Parameter | Type | Description | | ------ | ------ | ------ | | `jws` | `string` \| [`Uint8Array`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) | Compact JWS. | | `key` | [`Uint8Array`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) \| [`CryptoKey`](https://developer.mozilla.org/docs/Web/API/CryptoKey) \| [`JWK`](../../../../types/interfaces/JWK.md) \| [`KeyObject`](../../../../types/interfaces/KeyObject.md) | Key to verify the JWS with. See [Algorithm Key Requirements](https://github.com/panva/jose/issues/210#jws-alg). | | `options?` | [`VerifyOptions`](../../../../types/interfaces/VerifyOptions.md) | JWS Verify options. | ### Returns [`Promise`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\<[`CompactVerifyResult`](../../../../types/interfaces/CompactVerifyResult.md)\> ### Example ```js const jws = 'eyJhbGciOiJFUzI1NiJ9.SXTigJlzIGEgZGFuZ2Vyb3VzIGJ1c2luZXNzLCBGcm9kbywgZ29pbmcgb3V0IHlvdXIgZG9vci4.kkAs_gPPxWMI3rHuVlxHaTPfDWDoqdI8jSvuSmqV-8IHIWXg9mcAeC9ggV-45ZHRbiRJ3obUIFo1rHphPA5URg' const { payload, protectedHeader } = await jose.compactVerify(jws, publicKey) console.log(protectedHeader) console.log(new TextDecoder().decode(payload)) ``` ## Call Signature ▸ **compactVerify**(`jws`, `getKey`, `options?`): [`Promise`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\<[`CompactVerifyResult`](../../../../types/interfaces/CompactVerifyResult.md) & [`ResolvedKey`](../../../../types/interfaces/ResolvedKey.md)\> ### Parameters | Parameter | Type | Description | | ------ | ------ | ------ | | `jws` | `string` \| [`Uint8Array`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) | Compact JWS. | | `getKey` | [`CompactVerifyGetKey`](../interfaces/CompactVerifyGetKey.md) | Function resolving a key to verify the JWS with. See [Algorithm Key Requirements](https://github.com/panva/jose/issues/210#jws-alg). | | `options?` | [`VerifyOptions`](../../../../types/interfaces/VerifyOptions.md) | JWS Verify options. | ### Returns [`Promise`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\<[`CompactVerifyResult`](../../../../types/interfaces/CompactVerifyResult.md) & [`ResolvedKey`](../../../../types/interfaces/ResolvedKey.md)\>
