Both compiled versions are are from OpenSSL 1.0.2-beta1. The 64 bit version was compiled under Opensuse 12.3 32 bit version was compiled under Ubuntu 12.04 LTS Both are statically linked, except a few libraries which are nowadays sometimes hard to link in, i.e. the dynamic loader (libdl) and glibc (libc). If you want to compile OpenSSL yourself, here are the configure options: for 32 Bit: --prefix=/usr/ --openssldir=/etc/ssl enable-zlib enable-ssl2 enable-rc5 enable-rc2 enable-gost enable-cms enable-md2 enable-mdc2 enable-rc5 enable-ec enable-ec2m enable-ecdh enable-ecdsa enable-seed enable-idea -Wa,--noexecstack no-dane no-ec_nistp_64_gcc_128 no-gmp no-jpake no-krb5 no-libunbound no-multiblock no-rfc3779 no-sctp no-shared no-ssl-trace no-store no-zlib-dynamic static-engine for 64Bit: --prefix=/usr/ --openssldir=/etc/ssl enable-zlib enable-ssl2 enable-ec_nistp_64_gcc_128 enable-rc5 enable-rc2 enable-gost enable-cms enable-md2 enable-mdc2 enable-rc5 enable-ec enable-ec2m enable-ecdh enable-ecdsa enable-seed enable-idea -Wa,--noexecstack no-dane no-gmp no-jpake no-krb5 no-libunbound no-multiblock no-rfc3779 no-sctp no-shared no-ssl-trace no-store no-zlib-dynamic static-engine And: You have to patch the sources, see file vanilla.patch otherwise ypu miss the experimental and some RC4/MD5 cipher suites. "openssl ciphers -V | wc -l" lists for me 112 ciphers as opposed to 82 from Ubuntu or Opensuse. Enjoy, Dirk
