ReadonlyalgorithmThe read-only algorithm property of the CryptoKey interface returns an object describing the algorithm for which this key can be used, and any associated extra parameters.
ReadonlyextractableThe read-only extractable property of the CryptoKey interface indicates whether or not the key may be extracted using SubtleCrypto.exportKey() or SubtleCrypto.wrapKey().
ReadonlytypeThe read-only type property of the CryptoKey interface indicates which kind of key is represented by the object.
ReadonlyusagesThe read-only usages property of the CryptoKey interface indicates what can be done with the key.
The
CryptoKeyinterface of the Web Crypto API represents a cryptographic key obtained from one of the SubtleCrypto methods SubtleCrypto.generateKey, SubtleCrypto.deriveKey, SubtleCrypto.importKey, or SubtleCrypto.unwrapKey. Available only in secure contexts.MDN Reference
