Hardware Crypto Accelerator in visionfive 2


I am using the VisionFive-2 board and checking the Hardware Crypto accelerator using the cryptode-linux application.
I have verified the AES-128, 192, & 256-bit with all the modes (ECB, CBC, OFB, CFB , CTR, GCM & CCM). and but we are observing AES-192 bit is not encrypting as expected.

1. Can anyone provide me with a detailed document for the Hardware crypto accelerator?
2. Is the 192 bit is available on the VisionFive-2…?
