  - QNX Cryptography Library
    The QNX Cryptography Library (qcrypto) is a flexible cryptography framework that allows you to choose which cryptography provider responds to requests on a per-process basis.
    - 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.
    - Configuration File
      The qcrypto library configuration file allows the system integrator to define which cryptography providers are supported and available to the system.
    - Adding Cryptographic Primitives
      The libqcrypto_pluginS.a plugin library and qcrypto/qcrypto_plugin.h header file allow you to create a custom plugin to use with the qcrypto library.
    - Supported Primitives
      The qcrypto library provides a consistent API to cryptographic primitives offered by third-party libraries.
      - Key generation and usage
        The qcrypto library supports various types of cryptographic keys.
      - Digests
        The qcrypto library API includes cryptographic digest (hashing) functions.
      - Symmetric cryptography (ciphers)
        The qcrypto library API includes cryptographic cipher functions.
      - Message authentication code (MAC)
        The qcrypto library API includes cryptographic MAC functions.
      - Key Derivation Function (KDF)
        The qcrypto library API includes cryptographic KDF functions.
      - Random number generator (RNG)
        The qcrypto library API includes RNG functions.
      - Digital signing and verification
        The qcrypto library API includes functions that provide cryptographic signing and verification primitives. Several forms are provided to give you the flexibility of using one that is best suited to your needs.
      - Padding
        Some cryptographic primitives, such as AES ciphers in block cipher modes of operation, often require that the input data size be a multiple of the primitive's block size. Because the size of some data (e.g., plaintext) can be variable, padding can be added to meet the primitive's size requirements.
