method

crypto.webcrypto.SubtleCrypto.importKey

format: 'jwk',

extractable: boolean,

keyUsages: readonly KeyUsage[]

): Promise<CryptoKey>;

This 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 a {CryptoKey} representation of the key material.

If importing KDF algorithm keys, extractable must be false.

@param format

Must be one of 'raw', 'pkcs8', 'spki', 'jwk', 'raw-secret', 'raw-public', or 'raw-seed'.

@param keyUsages

See Key usages.
