Network Security with OpenSSL
"If you have struggled with OpenSSL and the supplied documentation then you will regret the amount of time that you have wasted before finding this book. If you are planning to use OpenSSL then you need to buy a copy - it's essential reading. What is more surprising is that even if you don't plan to use OpenSSL, then downloading it and trying out the examples in the book could be the education in practical cryptography you really need. What more can I say of any book, other than that I certainly won't be lending it to anyone else? It's going to remain firmly chained to my bookshelf for the foreseeable future - and no, you can't borrow it." - Mike James, VSJ, October 2003
