method SubtleCrypto.deriveKey
#SubtleCrypto.deriveKey(
baseKey: CryptoKey,
extractable: boolean,
keyUsages: KeyUsage[],
): Promise<CryptoKey>

This method is used to derive a secret key from a base or master key using a cryptographic algorithm. It returns a Promise which fulfils with an object of the new key.

Examples #

#
// Derive a key using an HKDF algorithm
await crypto.subtle.deriveKey("HKDF", baseKey, derivedKeyType, extractable, keyUsages);

Parameters #

#baseKey: CryptoKey
#extractable: boolean
#keyUsages: KeyUsage[]

Return Type #

Promise<CryptoKey>
