Abstract: A system comprises a computer device, such as a host apparatus, a second device, such as a digital signage player, which is connectable to the computer device, and an external device connectable to the second device. The computer device sends a command to the second device. The command causes the second device to send a message to the external device. The command includes destination information for the external device and a command payload, whereby the second device can be controlled to send a message to the external device corresponding to the destination information with a message payload corresponding to the command payload and compatible with the external device.

Abstract: The disclosure provides an approach for certificate management for cryptographic agility. Embodiments include receiving, by a cryptographic agility system, a cryptographic request related to an application. Embodiments include selecting, by the cryptographic agility system, a cryptographic technique based on contextual information associated with the cryptographic request. Embodiments include determining, by the cryptographic agility system, based on the cryptographic request, a certificate for authenticating a key related to the cryptographic technique. Embodiments include providing, by the cryptographic agility system, the certificate to an endpoint related to the cryptographic request for use in authenticating the key.

Abstract: The disclosure provides an approach for cryptographic agility. Embodiments include establishing, by a proxy component associated with a cryptographic agility system, a first secure connection with an application. Embodiments include receiving, by the proxy component, via the first secure connection, a communication from the application directed to an endpoint. Embodiments include selecting, by the cryptographic agility system, a cryptographic technique based on contextual information related to the communication. Embodiments include establishing, by the proxy component, a second secure connection with the endpoint based on the cryptographic technique. Embodiments include transmitting, by the proxy component, a secure communication to the endpoint via the second secure connection based on the communication.
