Dear Fiware,

I have deployed at Fiware Lab one instance of the idm-keyrock based on image "keyrock-R5.3.0". The IDM works under protocol http and default port 8000 with no problems.

I have installed Apache Web Server to setup with SSL certificates signed by a CA and the website works 1 or 2 times and then I get at the error file of apache the messages appears below

AH01990: PRNG still contains insufficient entropy!

extern "Python": function Cryptographyrandbytes() called, but @ffi.def_extern() was not called in the current subinterpreter. Returning 0.

Any tip or help to solve this problem is wellcome

Many thanks in advance for your support!

Best Regards

It seems to be a problem with Cryptography lib. I see several forums in which developers propose solutions to it.

I have tested some proposals and they does not work. Is it possible get a running instance of idm-keyrock configured with apache web server and ssl? Best regards

I have deployed a new instance of IDM-keyrock at FiwareLab, I have configured Apache under SSL with certificates signed by a CA and I get again the Entrophy Error. So the instance avaliable at FiwareLab of the GE focused on Security does not work under secure protocol. It seems to be like a joke ;-(

I have deployed an instance of WIRECLOUD at FiwareLab. I have configured Apache under SSL with certificates signed by a CA and eveything works OK!!! No entrophy errors. Wirecloud and KeyRock have the same versions of Apache/2.4.7 and Python 2.7.6. This can be helpful to find a solution for KeyRock?
