title: How to install latest version of openssl Mac OS X El Capitan
body: <p>I have used <code>brew install openssl</code> to download and install openssl v1.0.2f, however, it comes back saying:</p>
  
  <pre><code>A CA file has been bootstrapped using certificates from the system
  keychain. To add additional certificates, place .pem files in
    /usr/local/etc/openssl/certs
  
  and run
    /usr/local/opt/openssl/bin/c_rehash
  
  This formula is keg-only, which means it was not symlinked into /usr/local.
  
  Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries
  
  Generally there are no consequences of this for you. If you build your
  own software and it requires this formula, you'll need to add to your
  build variables:
  
      LDFLAGS:  -L/usr/local/opt/openssl/lib
      CPPFLAGS: -I/usr/local/opt/openssl/include
  </code></pre>
  
  <p>And when I do <code>openssl version -a</code> it always gives me:</p>
  
  <pre><code>OpenSSL 0.9.8zg 14 July 2015
  built on: Jul 31 2015
  platform: darwin64-x86_64-llvm
  options:  bn(64,64) md2(int) rc4(ptr,char) des(idx,cisc,16,int) blowfish(idx) 
  compiler: -arch x86_64 -fmessage-length=0 -pipe -Wno-trigraphs -fpascal-strings -fasm-blocks -O3 -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DL_ENDIAN -DMD32_REG_T=int -DOPENSSL_NO_IDEA -DOPENSSL_PIC -DOPENSSL_THREADS -DZLIB -mmacosx-version-min=10.6
  OPENSSLDIR: "/System/Library/OpenSSL"
  </code></pre>
  
  <p>How can I replace the old version with the new one? I've searched a lot on how to do this, but the solutions online don't seem to work for me...</p>
