Which version I should use?

[liorko87]

We are using OpenSSL 1.0.2 version. Right now scapi doesn't support OpenSSL 1.1. OpenSSL changes his interface in version 1.1 (you can read more details here and that's the reason why you are getting this error.

I tried to downgrade my openssl but I couldn't. when I tryied to install it by apt-get (telling the specific version), there were some errors because version 1.0 is not in repositories now, when I tried to install it from source, everything seems well, but when i check the version of my openssl, it's still 1.1.1 ! Would you please give me some help with this?

We are now working on convert scapi to OpenSSL version 1.1.0>.

Something is very confusing for me! when I want to see my openssl version and type command "openssl version", it tells me "OpenSSL 1.1.1-dev xx XXX xxx" but openssl doesn't have 1.1.1 version, the newest version of openssl is 1.1.0 !! I am really stuck! I think these problem is made after installing scapi in java, because in scapi/lib/openssl/readme I see this sentence : OpenSSL 1.1.1-dev exactly the same thing that i saw in my terminal. So i have two questions: 1- Why openssl that i have in scapi libraries tell me that its version is 1.1.1, when there isn't such a version for openssl? 2- How can I remove java scapi completely, so I can install c++ version instead?

[liorko87]

OpenSSL version 1.1.1 exists. You can found here the source code

[fatemehajikarami]

Yes you are right, this is under develop version! I should remove this and install 1.0.2 version. How can remove scapi (java version) completely?

Hi I remove openssl 1.1.1, now my openssl is : OpenSSL 1.0.2g 1 Mar 2016 But i still get error in making scapi: Compiling the OtExtension library... make[1]: Entering directory '/home/hajikarami/libscapi/build/OTExtension' In file included from cbitvector.cpp:8:0: cbitvector.h:296:16: error: field ‘m_nKey’ has incomplete type ‘EVP_CIPHER_CTX {aka evp_cipher_ctx_st}’ AES_KEY_CTX m_nKey; ^ In file included from /usr/local/include/openssl/evp.h:14:0, from ../util/typedefs.h:15, from cbitvector.h:18, from cbitvector.cpp:8: /usr/local/include/openssl/ossl_typ.h:90:16: note: forward declaration of ‘EVP_CIPHER_CTX {aka struct evp_cipher_ctx_st}’ typedef struct evp_cipher_ctx_st EVP_CIPHER_CTX; ^ Makefile:55: recipe for target 'util/*.o' failed make[1]: *** [util/*.o] Error 1 make[1]: Leaving directory '/home/hajikarami/libscapi/build/OTExtension' makefile:110: recipe for target 'compile-otextension' failed make: *** [compile-otextension] Error 2

It seems that It doesn't recognize the OpenSSL version that you installed manually.
Yo can look here to see how to link the new OpenSSL.

We are currently working on converting libscapi to the new version of OpenSSL.

I've installed Scapi on ubuntu 14, but when I want to install it on ubuntu 16.0.4, I get some errors: /usr/lib/jvm/java-8-openjdk-amd64/include/jni.h:45:20: fatal error: jni_md.h: No such file or directory compilation terminated. makefile:49: recipe for target 'OTExtensionMaliciousReceiver.o' failed make[1]: *** [OTExtensionMaliciousReceiver.o] Error 1 make[1]: Leaving directory '/home/serveradmin/scapi/src/jni/MaliciousOtExtensionJavaInterface' makefile:236: recipe for target 'src/jni/MaliciousOtExtensionJavaInterface/libMaliciousOtExtensionJavaInterface.so' failed make: *** [src/jni/MaliciousOtExtensionJavaInterface/libMaliciousOtExtensionJavaInterface.so] Error 2 Is there any problem with installation on ubuntu 16.0.4?

[liorko87]

I assume that you are dealing with scapi java version.
I installed it today on clean Ubuntu 16.04 machine. There is a problem with the new jdk 1.8.
It seems that the location of jni_md.h has changed.
please run the following code before make:

sudo cp /usr/lib/jvm/java-8-openjdk-amd64/include/linux/jni_md.h /usr/lib/jvm/java-8-openjdk-amd64/include/

thank you so much, I installed it successfully. Now when I create DlogExample.java and try to run "scapic DlogExample.java", I get these errors? I dont know why!
