Integration update: wolfSSL is the Secure Socket Solution for Qt

    • The QSslSocket class in Qt makes it easy to add encryption to your application. wolfSSL makes it secure!

    The wolfSSL embedded SSL/TLS library is a lightweight SSL/TLS library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments – primarily because of its small size, speed, and feature set.  It is commonly used in standard operating environments as well because of its royalty-free pricing and excellent cross-platform support. wolfSSL supports industry standards up to the current TLS 1.3 and DTLS 1.2 levels, is up to 20 times smaller than OpenSSL, supports FIPS, and has critical interfaces like TPM 2.0 and  PKCS#11.

    Qt has traditionally used OpenSSL as the provider for SSL/TLS in Qt Network for secure network communications. wolfSSL 4.4.0 adds support for building Qt 5.12 and 5.13 against the wolfSSL embedded SSL/TLS library instead of the default OpenSSL backend! The wolfSSL integration with Qt provides a performance-minded alternative, ideal for Qt developers who are looking for a lightweight, progressive, and well-tested SSL/TLS implementation.  

    Using wolfSSL as a TLS provider in Qt can have many advantages, depending on application and industry.  Some of these may include:
