  - QNX Cryptography Library
    The QNX cryptography library (qcrypto library) is a generic cryptographic shim layer that provides a consistent API to the various cryptographic primitives offered by third-party libraries.
  - The devcrypto service
    The devcrypto service is a legacy system driver interface and is mainly provided for backwards compatibility.
    - The devcrypto plugin API (devcrypto_plugin.h)
      The devcrypto plugin API allows you to create a software backend to the devcrypto service, which provides access to cryptographic accelerators.
    - Example devcrypto plugin: openssl_digest.c
      This example illustrates how to implement a devcrypto plugin.
    - The devcrypto I/O command API (cryptodev.h)
      The devcrypto API that provides I/O command structures.
  - Pathtrust
    The pathtrust feature prevents processes from executing untrusted code. If a process is compromised, pathtrust mitigates the threat of the system being further compromised by an attacker using chained-together exploits.
  - PAM
    Systems that need authentication can use pluggable authentication module (PAM), a configurable standard library.

The devcrypto service

QNX SDP8.0QNX OS System Security GuideAPIConfiguration

The devcrypto service is a legacy system driver interface and is mainly provided for backwards compatibility.

The QNX OS /dev/crypto is a driver that provides cryptography support through the "standard" /dev/crypto interface (similar to OpenBSD's cryptodev userspace API). It exposes an interface that uses I/O control calls to perform cryptography operations (MAC, digest, cipher, AEAD cipher, etc.).

The devcrypto plugin API allows you to create a software backend to devcrypto, which provides access to either software or hardware cryptographic accelerators.
