Abstract
A cryptographic accelerator may include an input buffer to store an additional authenticated data (AAD) portion of a message and a plain text portion of the message. The cryptographic accelerator may include a cryptographic engine to generate cipher text using the plain text portion of the message, generate a message authentication code (MAC) using the AAD portion and either the plain text portion or the cipher text, determine a configuration for creating an assembled message in an output buffer of the cryptographic accelerator, and provide at least the cipher text to the output buffer to create the assembled message in the output buffer according to the configuration. The cryptographic accelerator may include the output buffer to provide the assembled message.
