Imports a JWK to a runtime-specific key representation (KeyLike). Either JWK "alg" (Algorithm)
Parameter must be present or the optional "alg" argument. When running on a runtime using Web
Cryptography API the jwk parameters "use", "key_ops", and
"ext" are also used in the resulting CryptoKey
. See Algorithm Key
Requirements to learn about key to algorithm
requirements and mapping.

Name | 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. |
octAsKeyObject? |
boolean |
Forces a symmetric key to be imported to a KeyObject or CryptoKey. Default is true unless JWK "ext" (Extractable) is true. |
