A shell script to build OpenSSL for iOS and Mac. It currently builds: Mac -> i386 & x86_64 // iOS -> armv7, armv7s, arm64 // iOS Simulator -> i386 & x86_64.
#!/bin/bash
# This script builds the iOS and Mac openSSL libraries
# Download openssl http://www.openssl.org/source/ and place the tarball next to this script
