Bug #1589 ยป sign-bench.cpp

KeyChain::sign benchmark tool - Junxiao Shi, 05/10/2014 11:29 PM

 
// ndn-cxx KeyChain::sign benchmark tool
//
// Compile with:
// (OSX only) export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
// g++ -o sign-bench sign-bench.cpp `pkg-config --libs --cflags libndn-cxx`
//
// HOW TO USE
// 1. edit ~/.ndn/client.conf to choose between file or osx-keychain TPM
// (osx-keychain TPM is available on GUI mode only)
// 2. install a default certificate
// (after choosing correct TPM)
// 3. run this benchmark
// If "sign-bench wants to sign using key" popup appears, click [Always Allow],
// and rerun the benchmark.
