Here's our take.

wolfSSL

Nice Pick

Developers should learn and use wolfSSL when building applications for embedded systems, IoT devices, or any environment with limited memory and processing power, as it offers a minimal code size without sacrificing security

Pros

• It is ideal for use cases like secure firmware updates, device-to-cloud communication, and real-time operating systems where traditional TLS libraries are too heavy
• Related to: c-programming, embedded-systems

Cons

• Specific tradeoffs depend on your use case

OpenSSL

Developers should learn and use OpenSSL when building or maintaining systems that require secure data transmission, such as HTTPS web servers, VPNs, or encrypted messaging applications

Pros

• It is essential for implementing SSL/TLS certificates, generating cryptographic keys, and performing security audits in environments like Linux servers, where it is often the default tool for handling cryptographic operations
• Related to: tls-ssl, cryptography

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. wolfSSL is a library while OpenSSL is a tool. We picked wolfSSL based on overall popularity, but your choice depends on what you're building.

The Bottom Line

wolfSSL wins

Based on overall popularity. wolfSSL is more widely used, but OpenSSL excels in its own space.
