method webcrypto.SubtleCrypto.importKey
#SubtleCrypto.importKey(
format: "jwk",
keyData: JsonWebKey,
extractable: boolean,
keyUsages: readonly KeyUsage[],
): Promise<CryptoKey>

The subtle.importKey() method attempts to interpret the provided keyData as the given format to create a <CryptoKey> instance using the provided algorithm, extractable, and keyUsages arguments. If the import is successful, the returned promise will be resolved with the created <CryptoKey>.

If importing a 'PBKDF2' key, extractable must be false.

Parameters #

#format: "jwk"

Must be one of 'raw', 'pkcs8', 'spki', or 'jwk'.

#keyData: JsonWebKey
#extractable: boolean
#keyUsages: readonly KeyUsage[]

See Key usages.

Return Type #

Promise<CryptoKey>
#SubtleCrypto.importKey(
format: Exclude<KeyFormat, "jwk">,
keyData: BufferSource,

): Promise<CryptoKey>

Parameters #

#format: Exclude<KeyFormat, "jwk">
#keyData: BufferSource
#extractable: boolean
#keyUsages: KeyUsage[]

Return Type #

Promise<CryptoKey>
