wolfSSL for Espressif
wolfSSL is dedicated to ensuring all Espressif customers have access to world-class encryption libraries to secure connections.
Some of our mutual customers may have questions regarding Espressif no longer distributing static wolfSSL binaries and what this means for wolfSSL in the Espressif environment. We want everyone to know that wolfSSL fully embraces the Espressif ecosystem.
Having customers link directly to source code allows a more efficient distribution of wolfSSL library updates. This is particularly important as any vulnerabilities are found and fixed promptly in source code, but the static binaries outside of our control may not immediately be updated.
What does this mean for makers?
The source code for wolfSSL is dual-licensed under GPLV2. This means that makers can continue using wolfSSL encryption for free, as long as they abide by the terms of GPLV2.
What does this mean for commercial users?
Commercial users of the Espressif chips are encouraged to use the wolfSSL libraries to secure all end user connections with the robust and reliable wolfSSL libraries. There are a variety of licensing options for commercial users of all sizes. We also offer commercial support and dedicated consulting for optimization and tuning.
