MCUBootApp checks image integrity with SHA256, image authenticity with EC256 digital signature verification and uses completely SW implementation of cryptographic functions based on mbedTLS Library.
**Hardware cryptography acceleration:**
Cypress PSOC6 MCU family supports hardware acceleration of cryptography based on mbedTLS Library via shim layer. Implementation of this layer is supplied as separate submodule `cy-mbedtls-acceleration`. HW acceleration of cryptography shortens boot time more then 4 times, comparing to software implementation (observation results).
To enable hardware acceleration in `MCUBootApp` pass flag `USE_CRYPTO_HW=1` to `make` while build.
Hardware acceleration of cryptography is enabled for PSOC6 devices by default.
