# Using NetPGP instead of GnuPG

 ## Prepare

 Get OpenSSL:

 curl -O https://www.openssl.org/source/openssl-1.1.0f.tar.gz

 Build it using the openssl-for-ios build script:

 git clone https://github.com/sinofool/build-openssl-ios/ .

  and build/install it as shared library.

 ```

 wget https://www.openssl.org/source/old/1.0.1/openssl-1.0.1u.tar.gz

 tar xvfz openssl-1.0.1u.tar.gz

 cd openssl-1.0.1u

 ./Configure darwin64-x86_64-cc --prefix=$HOME shared

 make install

 ```

 Get and autoconf NetPGP

 ```

 cd $SRC

 hg clone https://pep.foundation/dev/repos/netpgp-et/

 cd netpgp-et

 autoreconf -i

 ```

 ## Build

 Important : LDFLAGS is set to help finding OpenSSL shared lib. If not set,

 system's default libcrypto may silently be used instead, causing memory

 corruption or crash at runtime.

 ```

 mkdir netpgp_debug

 cd netpgp_debug

 $SRC/netpgp-et/configure --with-openssl=$HOME --prefix=$HOME CPPFLAGS=-DDEBUG CXXFLAGS="-g -O0" LDFLAGS="-L${HOME}/lib"

 make

 make install

 ```
