OpenSSL is a widely used but poorly documented software, making it difficult for users to figure out how to use basic functionality like generating an RSA key. The documentation is scattered across multiple websites, often contradictory, and assumes a level of cryptographic knowledge that many users lack. Even simple tasks like determining the key format can be challenging due to the lack of clear guidance. The author highlights several usability issues with OpenSSL, such as the default use of a weak 512-bit RSA key, and the lack of warnings or guidance when using deprecated interfaces. The author argues that improving OpenSSL's usability through better documentation, user testing, and avoiding unnecessary forks could go a long way in making this critical piece of software more accessible to a wider audience.
