This script downloads and builds OpenSSL v1.0.2m and socat v1.7.3.2 in /usr/local/src. Once complete, a symlink at /usr/local/bin/socat-ssl23 is created so that you can run it with socat-ssl23.
Tested on Kali Linux:
curl -fsSL https://git.io/vFBDA | bash| # socat with sslv2 && sslv3 support for proxies | |
| # symlinks the built socat to /usr/local/bin/socat-ssl23 | |
| # | |
| # 2017 - @leonjza | |
| set -e | |
| # https://en.wikipedia.org/wiki/OpenSSL | |
| # sslv2 is ripped from 1.1.0 so build latest 1.0.2 | |
| opensslversion=1.0.2m | |
| socatversion=1.7.3.2 | |

| tar xvf openssl-$opensslversion.tar.gz | |
| cd openssl-$opensslversion | |
| ./config --prefix=`pwd`/local --openssldir=/usr/lib/ssl enable-ssl2 enable-ssl3 shared | |

| echo "OpenSSL build complete." | |
| # Next, socat! | |
| cd $working_directory | |
| echo "Downloading socat..." | |
| curl -s -O http://www.dest-unreach.org/socat/download/socat-$socatversion.tar.gz | |
| echo "Unpacking and building..." | |

| cd socat-$socatversion | |
| ./configure LIBS="-L$openssl_libs" CPPFLAGS="-I$openssl_include" | |

| echo "Creating symlink to new socat for 'socat-ssl23'..." | |
| ln -s `pwd`/socat /usr/local/bin/socat-ssl23 | |

Had the same problem. The executable doesn't search /usr/local/src/openssl-1.0.2m/local/lib/ on runtime.
Fixed by passing the -rpath option to the linker so that the executable searchs the path.
In line 46 append LDFLAGS="$openssl_rpath" and line 32 openssl_rpath="-Wl,-rpath,'\$\$ORIGIN/../openssl-$opensslversion/local/lib' -Wl,-z,origin"
then rebuild and it should be working
Thanks @franjo2016 / @dampfklon I moved the script to a repo here so I can actually get notifications on messages.
I run this script and it seemed to have downloaded and install everything, but when I trying using compiled app I get this error:
/usr/local/src/socat-1.7.3.2/socat: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
I verified that files exist in lib folder:
ls -l /usr/local/src/openssl-1.0.2m/local/lib/
total 8380

Any advice what is missing?
Thanks!
