28 - Disable Hardware Cryptography, Keep DRBG and Jitter Entropy

Summary

This fragment disables hardware-accelerated cryptography but retains pseudo-random generation (DRBG) and entropy from CPU jitter, favoring software-only randomness sources.

Configuration breakdown

Software-only cryptography

CONFIG_CRYPTO_DRBG
CONFIG_CRYPTO_JITTERENTROPY
CONFIG_CRYPTO_HW
  • Keeps deterministic random bit generator.

  • Keeps entropy generation from CPU jitter.

  • Disables hardware crypto support.
