Kekeo - A Little Toolbox To Play With Microsoft Kerberos In C

kekeo is a little toolbox I have started to manipulate Microsoft Kerberos in C (and for fun)

ASN.1 library

In kekeo, I use an external commercial library to deal with Kerberos ASN.1 structures: OSS ASN.1/C (http://www.oss.com/asn1/products/asn1-c/asn1-c.html)
It was the only code generator/library that I've found to work easily with Microsoft C project.

works without a lots of dependencies;
magical documentation;
wonderful support for my stupid questions;
had a binary that work only few hours after started my project...

They were kind enough to offer me a 1-year licence.
With this one, I'm able to let you download binaries that run in your environment.
So don't forget to thank them ( http://www.oss.com/company/contact-us.html / https://twitter.com/OSSNokalva )

Limitations

Binaries will work until December 21, 2017 (yeah, 1 year licence ;));
You must buy a licence from OSS ASN.1/C (or download a trial version) to build kekeo solution/adapt it.

- When you register for a free trial, don't forget to refer me in the description field ;) (kekeo or gentilkiwi)

Building kekeo with ASN.1/C

You can't build kekeo out-of-the-box, you'have to generate C files and link with OSS libraries.

After downloading and installing a commercial/trial version of OSS ASN.1/C, Win32 and/or x64:

Open a command prompt in ($kekeo)\modules\asn1
Adapt the ASN1C variable to your ASN.1/C configuration (architecture & version)
```
set ASN1C="C:\Program Files\OSS Nokalva\ossasn1\winx64\10.4.0"
```

Depending on the targeted lib architecture:

Win32

%ASN1C%\bin\asn1.exe ^
  %ASN1C%\asn1dflt\asn1dflt.ms.zp4 ^
  KerberosV5Spec2.asn KerberosV5-PK-INIT-SPEC.asn PKIX1Explicit88.asn PKINIT.asn MS-SFU-KILE.asn ^
  -noSampleCode -der -root -CStyleComments -externalName kekeo_asn1 -messageFormat msvc -verbose ^
  -headerFile kull_m_kerberos_oss_asn1_internal.h -soedFile kull_m_kerberos_oss_asn1_internal_Win32.c

x64

%ASN1C%\bin\asn1.exe ^
  %ASN1C%\asn1dflt\asn1dflt.msx64.zp8 ^
  KerberosV5Spec2.asn KerberosV5-PK-INIT-SPEC.asn PKIX1Explicit88.asn PKINIT.asn MS-SFU-KILE.asn ^
  -noSampleCode -der -root -CStyleComments -externalName kekeo_asn1 -messageFormat msvc -verbose ^
  -headerFile kull_m_kerberos_oss_asn1_internal.h -soedFile kull_m_kerberos_oss_asn1_internal_x64.c

Header file kull_m_kerberos_oss_asn1_internal.h is the same for both architecture.

Copy from OSS ASN.1/C install dir (eg: C:\Program Files\OSS Nokalva\ossasn1\winx64\10.4.0)
- include\ossasn1.h to ($kekeo)\inc
- include\osstype.h to ($kekeo)\inc
- lib\soeddefa.libto ($kekeo)\lib\{Win32 or x64}
- lib\ossiphlp.libto ($kekeo)\lib\{Win32 or x64}
