▸ importJWK(jwk, alg?, options?): Promise<Uint8Array | CryptoKey>

Imports a JWK to a CryptoKey. Either the JWK "alg" (Algorithm) Parameter, or the optional "alg" argument, must be present for asymmetric JSON Web Key imports.

[!NOTE]
The JSON Web Key parameters "use", "key_ops", and "ext" are also used in the CryptoKey import process.

[!NOTE]
Symmetric JSON Web Keys (i.e. kty: "oct") yield back an Uint8Array instead of a CryptoKey.

This function is exported (as a named export) from the main 'jose' module entry point as well as from its subpath export 'jose/key/import'.

Parameters

Parameter	Type	Description
`jwk`	`JWK`	JSON Web Key.
`alg?`	`string`	JSON Web Algorithm identifier to be used with the imported key. Default is the "alg" property on the JWK. See Algorithm Key Requirements.
`options?`	`KeyImportOptions`	-

Returns

Promise<Uint8Array | CryptoKey>
