Make Your Apps Safer with an Embedded SSL Library

Developers are under more pressure than ever before to implement security as a core design element in all their projects. The concept of being secure by design is now expected by many business customers, rather than simply something that gets tacked on later after the rest of the project has been complete. As such, the ability to encrypt data in any app that involves the transmission of potentially sensitive data is an essential feature to have. wolfSSL provides that much-needed functionality in the form of a very lightweight library that’s only a twentieth of the size of the industry-standard OpenSSL. When it comes to mobile apps in particular, that’s a substantial benefit, since it can significantly reduce the size of the app and its installer without compromising on security.

wolfSSL works with real-time operating systems, embedded devices and almost any resource-contained environment to offer a maximum level of security while taking up minimal space and other resources. This is highly beneficial in such applications, not least because embedded devices generally only have a small amount of storage space that cannot be upgraded. Furthermore, the TLS library offers uncompromising security per the standards of the latest TSL protocol.

Designed with Versatility in Mind

Many software libraries are particularly restrictive and will only work with specific platforms and programming languages. Open-source solutions often don’t have these restrictions, but they often come with a degree of feature bloat as well or have other problems. When it comes to digital security, you cannot afford to compromise. wolfSSL has been developed with the global marketplace in mind so that many hardware and software developers can find a valuable use for it. It’s a very portable library as well, making it easier to compile and adapt to your needs. Out of the box, wolfSSL supports the world’s most popular programming language – C. The library also provides native support for Perl, C#, Java, Python and PHP. Even in the unlikely event that your preferred platform isn’t officially supported, it can still be made to work with a variety of other host programming languages thanks to additional support from the community.

What Is Performance Like?

Portability by way of small library size isn’t the only way in which wolfSSL outdoes the competition. It also offers exceptional performance, because security shouldn’t always have to mean compromising on everything else. It uses minimal memory and storage space, which is important given that the average size for embedded systems is just a few megabytes. Despite this, wolfSSL still includes a full-featured TLS 1.2 client and server that meets all the necessary industry standards of the TLS protocol.

Developers can also choose from a variety of builds, the most popular being LeanPSK, which is a recently implemented solution that brings the library size down to only 20 kilobytes. However, for this solution to work, pre-shared keys (PSKs) are necessary. Developers working with other platforms, which are not officially supported, can subscribe for additional support to get the assistance they need to integrate the library with other programing languages.
