-// AlgorithmImplementation is a base class for *executing* the operations of an
-// algorithm (generating keys, encrypting, signing, etc.).
-//
-// This is in contrast to blink::WebCryptoAlgorithm which instead *describes*
-// the operation and its parameters.
-//
-// AlgorithmImplementation has reasonable default implementations for all
-// methods which behave as if the operation is it is unsupported, so
-// implementations need only override the applicable methods.
-//
-// Unless stated otherwise methods of AlgorithmImplementation are responsible
-// for sanitizing their inputs. The following can be assumed:
-//
-//   * |algorithm.id()| and |key.algorithm.id()| matches the algorithm under
-//     which the implementation was registerd.
-//   * |algorithm| has the correct parameters type for the operation.
-//   * The key usages have already been verified. In fact in the case of calls
-//     to Encrypt()/Decrypt() the corresponding key usages may not be present
-//     (when wrapping/unwrapping).
