OpenSSL is probably the entire package can be divided into three major functional components: cryptographic algorithm library, SSL protocol libraries and applications. OpenSSL directory structure around these three functions naturally part of planning. As a cryptography-based security development kits, OpenSSL provides quite powerful and comprehensive, covering the major cryptographic algorithms, commonly used key and certificate management functions as well as the SSL protocol encapsulation, and provides a rich set of applications for testing or other purposes.
