  • Publication number: 20190132120
    Abstract: In response to determining that an encryption operation request includes no indication of a cryptographic key, an encryption service module performs an encryption operation using a current cryptographic key retrieved by the encryption service module, and creates and stores an encrypted data object that includes the resulting ciphertext and a key identifier that uniquely identifies the cryptographic key and the associated cryptographic algorithm used to perform the encryption. A subsequent decryption operation request to the encryption service module that indicates the encrypted data object is processed by retrieving the cryptographic key and identifying the associated cryptographic using the key identifier contained in the encrypted data object. The encrypted data object may also include an initialization vector used to generate the ciphertext contained in the encrypted data object, as well as an integrity check value generated across the ciphertext and initialization vector.

The solenoid device includes an armature, and the piston pump includes a sleeve, a piston, an inlet valve, and an outlet valve. The sleeve includes an inner sleeve bore. The inner sleeve bore conforms with the external surface of the piston and can slide freely. The piston pump divides the interior pump body into a low-pressure space and a pressure feed space. Liquid enters the pressure feed space from the low pressure space through the inlet valve and is output through the outlet valve, wherein the sleeve connects with the armature and keeps synchronous reciprocating motions. The solenoid-driven device drives the sleeve to perform a motion relative to the piston, causing output of liquid. The output quantity of liquid due to such relative motion is defined by the geometric construction.
