Stratix SDM Encryption Accelerator?

Sorry, I missed your reply as all of Intel's emails are considered Junk by Office365.

This is the whitepaper. See page 2, "Encryption Support Hardware".

All I want to do if to find out how to use the stated features as no public documentation exists for them.

Excerpt below, (emphasis added):

The SDM uses these blocks during the configuration (and

reconfiguration) process; however, these accelerator

blocks are also available for user applications after device

configuration with appropriate licensing through the Intel

Quartus® Prime software. For example, designs could use

these blocks for encryption/decryption of data traffic in user

applications, as well as authenticating messages to and from

the FPGA. Service requests to these blocks come through

either the FPGA fabric or the ARM* Cortex*-A53 HPS system

to a request mailbox in the SDM, which instructs the blocks

to perform encryption, decryption, hashing, signing, or

signature checking functions.
