DLLs work on Windows but not on Android

Thank you very much. I've noticed something in the App.config of the repository.

 <dllmap os="osx" dll="libeay32" target="libcrypto.1.0.0.dylib"/>
 <dllmap os="osx" dll="ssleay32" target="libssl.1.0.0.dylib"/>
 <dllmap os="!windows,osx" dll="libeay32" target="libcrypto.so"/>
 <dllmap os="!windows,osx" dll="ssleay32" target="libssl.so"/>

So I'm wondering, will it work if I add a dllmap targeting Android to use libcrypto.so and libssl.so ? Sound to me that's a step in the right direction, but then there's the possiblity that I need to build the dll's on Android or perhaps I should build the dll's on Linux if Android is a flavor of Linux. To make it even more complicated, this should also work on iPhones and iPads.

I Think just building for android/linux should do the trick because the ddlmaps refer to libcrypto.so and libssl.so

Update: I've used a linux virtual box with CentOS 7 to get the .so files. It coincidentally had the exactly right version of OpenSSL installed(1.0.2k) but it could not find libcrypto.so or libssl.so so I used "yum provides libcrypto.so.10" to find out how to get these files on the virtual machine. After installing it "yum install libcrypto.so.10" I could use "find / -name libcrypto.so.10" and "find / -name libssl.so.10" to discover where these files were located. They were called libcrypto.so.1.0.2k and libssl.so.1.0.2k. I transfered the 32bit and 64bit versions to my work computer using ftp, removed ".1.0.2k" from all of them so they had the neutral libcrypto.so and libssl.so names as desired by the configuration file in the git repostory in my first post. I dropped them in the appropriate directory in my unity project:
Assets/Plugins/Android/libs/x86/
Assets/Plugins/Android/libs/armeabi-v7a/
Then I built the project for android and checked adb logcat for any errors and ufortunately it gave me the exact same errors described in my first post.
I feel like I'm getting very close but it still does not work. Is there anyone who can help me out a little bit more? Thanks in advance

Update: I've edited the $$anonymous$$anagedOpenSSL dll to skip the dllmap configuration. I think that only works when used outside of Unity. I built two ($$anonymous$$anagedOpenSSL) dll's one that searches for the windows libraries and one that searches for the android libraries. const string DLLNA$$anonymous$$E = "crypto"; Is used on android and DLLNA$$anonymous$$E is used in every [DllImport] attribute which would link the native C methods to C# calls. The actual "dll's" are called libcrypto.so and libssl.so but to make it work for Android people should remove the lib part and extension which results in calls to crypto and ssl. At this moment, OpenSSL works on Windows in the Unity editor. On Android however, I get a number of errors:

01-03 15:32:50.743 2573 2616 D Unity : Unable to load library '/system/lib/libcrypto.so', native render plugin support disabled: java.lang.UnsatisfiedLinkError: dlopen failed: library "/system/lib/libcrypto.so" needed or dlopened by "/system/lib/libnativeloader.so" is not accessible for the namespace "classloader-namespace"

01-03 15:32:51.312 2573 2616 E Unity : DllNotFoundException: crypto

It seems to search for libcrypto.so(the right name) in /system/lib/ which to me sounds like it's not loading it from the one I've added to the Unity folder but it's actually searching for it on the device. How would I link that back to the one I've actually added to the Unity project?

@Dread$$anonymous$$yller Could you maybe clarify a bit more about the problem and possible solution?

Thanks in advance

I've moved the entire $$anonymous$$anagedOpenSLL source code to my Unity project to be able to use Unity's platform dependent compilation. Changed the const string part to:
#if UNITY_EDITOR || UNITY_STANDALONE_WIN
const string DLLNA$$anonymous$$E = "libeay32";
const string SSLDLLNA$$anonymous$$E = "ssleay32";
#elif UNITY_ANDROID || UNITY_STANDALONE_LINUX
const string DLLNA$$anonymous$$E = "crypto";
const string SSLDLLNA$$anonymous$$E = "ssl";
#elif UNITY_IOS || UNITY_STANDALONE_OSX
no support yet
#endif

It works on Windows but when I run this on android I get the exact same error as in the previous comment. It's still searching for the /system/lib/libcrypto.so ins$$anonymous$$d of loading it from Unity.
