Crypto Engine

The HW crypto engine provides acceleration of many crypto algorithms such as hashing, secret key

generation, encryption/decryption and sign/verify operations.

Table 32 shows the HW accelerated crypto algorithms supported by the DA16200. This table is cited

from Ref. [4]. Examples of how to use these crypto algorithms are explained in Ref. [2].
