Are you looking for an SSL/TLS library which will seamlessly integrate into your bare metal or No-OS environment? If so, continue reading to learn why the wolfSSL lightweight SSL library is a perfect fit for such environments.
wolfSSL has been designed with portability and ease of use in mind, allowing developers to easily integrate it into a bare metal or operating systemless environment. As a large percentage of wolfSSL users are running the library on small, embedded devices, we have added several abstraction layers which make tying wolfSSL into these types of environments an easy task.
Available abstraction layers include:
- Custom Input/Output
- Standard C library / Memory
- File system (Able to use cert/key buffers instead)
- Operating System
In addition to abstraction layers, we have tried to keep wolfSSL’s memory usage as low as possible. Build sizes for a complete SSL/TLS stack range from 20-100kB depending on build options, with RAM usage between 1-36kB per connection.
