1189. [func] fdupont
Owing to API changes, crypto code now requires OpenSSL 1.0.1 or
later.

Kea supports two cryptographic libraries: Botan and OpenSSL. Only one of
them is required to be installed during compilation. If using Botan, Kea
requires the Botan cryptographic library for C++ (<ulink
url="http://botan.randombit.net/"/>), version 1.8, 1.9 or 1.10. If
OpenSSL is used, (<ulink url="http://www.openssl.org/"/>), then Kea
requires the OpenSSL C++ library version 1.0.*. Support for later
versions of Botan and OpenSSL will be added in future releases of Kea.
