{{ APIRef("Web Crypto API") }}

The AesDerivedKeyParams dictionary of the Web Crypto API represents the object that should be passed as the derivedKeyType parameter into {{domxref("SubtleCrypto.deriveKey()")}}, when deriving an AES key: that is, when the algorithm is identified as any of AES-CBC, AES-CTR, AES-GCM, or AES-KW.

Instance properties

  • name
    • : A string. This should be set to AES-CBC, AES-CTR, AES-GCM, or AES-KW, depending on the algorithm you want to use.
  • length
    • : A Number — the length in bits of the key to generate. This must be one of: 128, 192, or 256.

Examples

See the examples for {{domxref("SubtleCrypto.deriveKey()")}}.

Browser compatibility

Browsers that support any of the AES-based algorithms for the {{domxref("SubtleCrypto.deriveKey()")}} method will support this type.
