NFD » ndn-cxx

ndn-cxx supports only one type of strong signature: SignatureSha256WithRsa.
Signing process of RSA algorithm is slow on some platforms with limited resources (e.g., raspberry-pi).
As a faster public-key signature algorithm, ECDSA seems to be a good alternative to RSA.

In order to support ECDSA, several tasks are required:

1. Add ECDSA signature wire format into NDN-TLV packet format spec #1650
2. Add SignatureSha256WithEcdsa in ndn-cxx.
3. Add PublicKey::getKeyType method.
4. Support KeyType in SecPublicInfo.
5. Support ECDSA in SecTpm.
   1. Support ECDSA in SecTpmOsx.
   2. Support ECDSA in SecTpmFile.
6. Update KeyChain to use ECDSA.
7. Update PublisherPublicKeyLocator selector matching code to recognize new signature type.
