The CryptoKey object represents a cryptographic key used for encryption,decryption,signing, or verification within the webcrypto module. The CryptoKey object is created using the SubtleCrypto.generateKey() or SubtleCrypto.importKey() methods.


typestringIndicates the type of the key material. Possible values are public, private, secret, unspecified, or unknown.
extractablebooleanIndicates whether the raw key material can be exported.
algorithmobjectAn object containing the algorithm used to generate or import the key.
usagesstring[]An array of strings indicating the cryptographic operations that the key can be used for. Possible values are encrypt, decrypt, sign, verify, deriveKey, deriveBits, wrapKey, and unwrapKey.
