-// Derives a key by calling the underlying deriveBits/getKeyLength/importKey
-// operations.
-//
-// Note that whereas the WebCrypto spec uses a single "derivedKeyType"
-// AlgorithmIdentifier in its specification of deriveKey(), here two separate
-// AlgorithmIdentifiers are used:
-//
-//   * |import_algorithm|  -- The parameters required by the derived key's
-//                            "importKey" operation.
-//
-//   * |key_length_algorithm| -- The parameters required by the derived key's
-//                               "get key length" operation.
-//
-// WebCryptoAlgorithm is not a flexible type like AlgorithmIdentifier (it cannot
-// be easily re-interpreted as a different parameter type).
-//
-// Therefore being provided with separate parameter types for the import
-// parameters and the key length parameters simplifies passing the right
-// parameters onto ImportKey() and GetKeyLength() respectively.
