Module atsamd_hal::pukcc
source · [−]Expand description
Public Key Cryptography Controller (PUKCC)
This module provides both low and high level abstractions for dealing with a PUKCC peripheral.
PUKCC consists of a set of functions (called services) hidden within a reserved region of memory. These functions usually make use of a separate piece of RAM to operate called CryptoRAM.
c_abi module contains raw structs and callable C-like function
definitions. Pukcc wraps this low-level access API and exposes it in a
safe manner.
WARNING!
This module has not been evaluated for correctness nor suitability for any use-case. Subtle implementation details may have catastrophic implications for the security of your cryptosystem, and users are advised to engage a cryptographer before making use of this module.
