interface CryptoKey

• readonly algorithm: KeyAlgorithm

  An object detailing the algorithm for which the key can be used along with additional algorithm-specific parameters.

• readonly extractable: boolean

  When true, the CryptoKey can be extracted using either subtleCrypto.exportKey() or subtleCrypto.wrapKey().

• readonly type: KeyType

  A string identifying whether the key is a symmetric ('secret') or asymmetric ('private' or 'public') key.

• readonly usages: KeyUsage[]

  An array of strings identifying the operations for which the key may be used.

  The possible usages are:

  • 'encrypt' - The key may be used to encrypt data.
  • 'decrypt' - The key may be used to decrypt data.
  • 'sign' - The key may be used to generate digital signatures.
  • 'verify' - The key may be used to verify digital signatures.
  • 'deriveKey' - The key may be used to derive a new key.
  • 'deriveBits' - The key may be used to derive bits.
  • 'wrapKey' - The key may be used to wrap another key.
  • 'unwrapKey' - The key may be used to unwrap another key.

  Valid key usages depend on the key algorithm (identified by cryptokey.algorithm.name).
