Sifive deliver a high level of API for the cryptographic function call SCL (SiFive Cryptographic Librarie). The HCA is the Hardware Cryptographic Accelerator for this librarie.

This example show how low level functions can be called (when hardware feature is present) to connect the HCA.

This example perform some AES-ECB, AES-CCM, AES-GCM cryptographic operation with test vector and verify the attended result.

it perform also SHA256 and SHA224 on "well formated" buffer (it is the upper API that is in charge to format the "human" entry to the "well formated" buffer for the HCA)

it perform a TRNG initialization and get some random Data.
