Crypto enabled/disabled blue field2

I am using the node with smartNIC on cloudlab. Here is the hardware description for it:
Device Type: BlueField2
Part Number: MBF2H516A-CENO_Ax
Description: Bluefield-2 SmartNIC 100GbE Dual-Port QSFP56; PCIe Gen4 x16; Crypto Disabled; 16GB on-board DDR; 1GbE OOB management; FHHL

It has crypto disabled.
I wonder whether that is from the hardware restriction like the smartNIC does not have the hardware accelerator or if there is a way to change it into a crypto enabled state.

Hi @cxinyic ,

Please refer to:


“The BlueField-2 DPU crypto-enabled versions include a BlueField-2 IC which supports accelerated cryptographic operations. In addition to specialized instructions for bulk cryptographic processing in the Arm cores, an offload hardware engine accelerates public-key cryptography, and random number generation is enabled.”

Best Regards,
