Tech stack & purpose

OpenSSL is a general-purpose cryptographic and transport layer security library that handles encryption, decryption, and TLS/SSL protocols. The project is built in C and C++, with configuration managed through a sophisticated platform-targeting system that allows compilation across diverse systems by specifying compiler commands, flags, assembler options, linking strategies, and platform-specific features. The build system uses a unified scheme with configuration files, build templates, and helper Perl modules to manage compilation across different target platforms and architectures.
