Compilation instructions
========================

The precompiled versions here are from an OpenSSL 1.0.2 fork
from Peter Mosmans. He has patched the master git branch
to support chacha20+poly1305 and other ciphers (CAMELIA 256 Bit).

CHACHA20+POLY1305 cipher suites from the official git repo didn't 
work for me work correctly, it's also likely they'll disappear shortly
(https://www.mail-archive.com/openssl-dev@openssl.org/msg34756.html).


General
-------

* 64 bit versions were compiled under Opensuse 12.3
* 32 bit versions were compiled under Ubuntu 12.04 LTS

Likely you cannot use older distributions, younger should work.
I provide for each distributions two sets of binaries:

* statically linked binaries (except a few libs which are nowadays difficult to statically link)
* dynamically linked binaries with MIT Kerberos support ("krb5" in the name)

For the latter you need a whopping bunch of kerberos libraries which you maybe need to 
install from your distributor (libgssapi_krb5, libkrb5, libcom_err, libk5crypto, libkrb5support, 
libkeyutils). For the 'static' binaries kerberos is not compiled in, so that's is not needed.

All binaries are signed with my gpg key (.asc files).


Compilation instructions
------------------------

If you want to compile OpenSSL yourself, here are the instructions:

1.) get openssl from Peter Mosmans' repo:

     git clone https://github.com/PeterMosmans/openssl
     cd openssl

2.) configure the damned thing. Options I used:

**for 64Bit:**

    ./config --prefix=/usr/ --openssldir=/etc/ssl enable-zlib enable-ssl2 enable-rc5 enable-rc2 enable-GOST \
    enable-cms enable-md2 enable-mdc2 enable-ec enable-ec2m enable-ecdh enable-ecdsa enable-seed enable-camellia \   
    enable-idea enable-rfc3779 enable-ec_nistp_64_gcc_128 --with-krb5-flavor=MIT experimental-jpake  

**for 32 Bit:**

    ./config --prefix=/usr/ --openssldir=/etc/ssl enable-zlib enable-ssl2 enable-rc5 enable-rc2 enable-GOST \
    enable-cms enable-md2 enable-mdc2 enable-ec enable-ec2m enable-ecdh enable-ecdsa enable-seed enable-camellia \
    enable-idea enable-rfc3779 no-ec_nistp_64_gcc_128 --with-krb5-flavor=MIT experimental-jpake 

Don't use -DTEMP_GOST_TLS, it currently breaks things and it is not needed for general GOST support.

If you don't have / don't want Kerberos libraries and devel rpms/debs, omit "--with-krb5-flavor=MIT". 
If you have other Kerberos flavors you need to figure out by yourself.

3.) make depend

4.) make

5.) make report (check whether it runs ok)

6.) "openssl ciphers -V ALL:COMPLEMENTOFALL | wc -l" lists for me 
     * 187 + 4 russian GOST ciphers -- including kerberos
     * 173 + 4 russian GOST ciphers without kerberos

as opposed to 111/109 from Ubuntu or Opensuse. 

Enjoy, Dirk

PS: **Never use these binaries for anything else then for testing**
