According to examples, an apparatus may include a first hardware component including a first memory and a first processor. The first processor may initiate pairing between the first hardware component and a second hardware component to establish a trusted relationship between the first hardware component and a second hardware component. In response to a successful pairing between the first hardware component and the second hardware component, the processor may compare a first setting of the first hardware component with a second setting of the second hardware component. In response to a determination that the second setting corresponds to the first setting, the processor may authorize operation of the second hardware component.

Pairing hardware components to authorize operation

Reprocessing of a replaceable supply component may include receiving from an encoding device and using an interface communicatively coupled to the encoding device, a request blob to reprocess a replaceable supply component. The method may include in response to cryptographically verifying the request blob, extracting from the request blob, a supply identifier and raw supply data. The method further includes using the supply identifier and raw supply data, generating a reprocess structure to append or amend original manufacturing data for the replaceable supply component, and providing a response blob to the encoding device, to designate the replaceable supply component as a reprocessed supply component.

Examples associated with firmware encryption are described. One example device firmware includes a base module. The base module controls a base function of the device. The device firmware also includes a first encrypted module that modifies a first function of the device. The first encrypted module is inactive until decrypted. A decryption module decrypts the first module using a first encryption key and controls activation of the first encrypted module.

Firmware module encryption

Examples described herein include methods for configuring deployed devices, such as printers and scanners, across a network. Such methods include parsing a manageable features message received from a deployed electronic device according to a common management framework protocol to determine specifications for a manageable feature of the deployed electronic device, generating a features object comprising the specification for the manageable feature according to the common management framework protocol, associating the features object to the deployed electronic device, generating a user interface based on the features object, and sending configuration message to the deployed electronic device based on user input received through the user interface and the features object.

Common management frameworks

Examples associated with printer authentication are described. One example print container includes a space for a supply of print material and an interface for delivering the print material to a printer to which the print container is connected. An authentication module provides an authentication signal to a decrypted module embedded in firmware of the printer. The decrypted firmware module is kept in an encrypted state until decrypted by a decryption module embedded in the firmware of the printer. The decrypted module is decrypted after the decryption module receives a decryption key after release of the printer.

The printer also includes a first encrypted firmware module that modifies a first function of the printer. The first encrypted module is inactive until decrypted. A firmware decryption module decrypts the first encrypted module upon receiving a first encryption key.
