compile and install cryptopp 7.0 on windows 10

Posted on Edited on In

Guide

  • windows 10 64-bit
  • crypto++ 7.0
  • vs 2015

compile

download crypto++ 7.0

open cryptest.sln with Visual Studio 2015

change Windows SDK Version from 8.1 to 10.0

png

compile cryptodll with Release x64 and we get cryptopp.dll and cryptopp.lib
png

sdk

copy headers to include, copy libs to lib and dlls to dll like this:
