OpenSSL is an ubiquitious SSL/TLS implementation and cryptography toolkit. It is widely used to manipulate keys and certificates for servers and clients and there are a lot of tutorials on how to use it from the command line.
This presentation attempts to go deeper into OpenSSL`s library and give an overview of its API. It will show how to programmatically calculate one-way hashes, perform symmetric and asymmetric encryption and create and verify message authentication codes and digital signatures. The concrete examples will include DES and AES ciphers, RSA and DSA encryption and decryption, Diffie-Hellman key exchange and a simple SSL-enabled application. Some particular algorithms can also be described in more details along with their mathematical properties if time permits but the presentation will be mostly example-driven.
