95 + Optimized Data packet signing

97 :ndn-cxx:`KeyChain::sign` method now pre-allocates :ndn-cxx:`EncodingBuffer`, requests
98 unsigned portion of :ndn-cxx:`Data` using ``Data::wireEncode(EncodingBuffer, true)``,
99 and then appends the resulting signature and prepends :ndn-cxx:`Data` packet header.

140^^^^^^^^^^
Alexander Afanasyev45312f52015-09-27 12:06:50 -0700141
142- ``SignatureSha256`` class, use :ndn-cxx:`DigestSha256` instead.
143
144- All :ndn-cxx:`Face` constructors that accept ``shared_ptr<io_service>``.
145
146 Use versions that accept reference to ``io_service`` object.
147
148- ``Face::ioService`` method, use :ndn-cxx:`Face::getIoService` instead.
149
150- :ndn-cxx:`Interest` constructor that accepts name, individual selectors, and individual
151 guiders as constructor parameters.
152
153 Use ``Interest().setX(...).setY(...)`` or use the overload taking ``Selectors``
154
155- ``name::Component::toEscapedString`` method, use :ndn-cxx:`name::Component::toUri` instead.
156
susmitf47cef62018-02-13 12:01:14 -0700157- ``SecPublicInfo::addPublicKey`` method, use ``SecPublicInfo::addKey`` instead.
Alexander Afanasyev45312f52015-09-27 12:06:50 -0700158
159- ``Tlv::ConentType`` constant (typo), use ``Tlv::ContentType`` instead.
160
161- ``CommandInterestGenerator`` and ``CommandInterestValidator`` utility classes.
162 :ndn-cxx:`ValidatorConfig` should be used instead.
163

165^^^^^^^
Alexander Afanasyev45312f52015-09-27 12:06:50 -0700166

Alexander Afanasyev45312f52015-09-27 12:06:50 -0700168
169- ``SecPublicInfoMemory`` and ``SecTpmMemory`` classes that were no longer used
170
171- Removing concept of periodic event from :ndn-cxx:`Scheduler`.
172
173 In applications, periodic events should be just re-scheduled within the callback for
174 single-shot events.
