▸ generateSecret(alg, options?): Promise<Uint8Array | CryptoKey>
Generates a symmetric secret key for a given JWA algorithm identifier.
Note: The secret key is generated with extractable set to false by default.
Note: Because A128CBC-HS256, A192CBC-HS384, and A256CBC-HS512 secrets cannot be represented as CryptoKey this method yields a Uint8Array for them instead.
This function is exported (as a named export) from the main 'jose' module entry point as well
as from its subpath export 'jose/generate/secret'.
| Parameter | Type | Description |
|---|---|---|
alg |
string |
JWA Algorithm Identifier to be used with the generated secret. See Algorithm Key Requirements. |

Additional options passed down to the secret generation. |
Promise<Uint8Array | CryptoKey>
const secret = await jose.generateSecret('HS256')
