Key Generating #12

Closed Kushal08 closed 8 years ago

Kushal08 commented 8 years ago

Hey, I am using th is code on my 64 bit ubuntu system. This command ccr -g sig --name "John Deo" It does not showing anything.I waited for two but keys are not generated. It is not ending. Please help me in this issue.

Can you install strace and post the output of

strace ccr -g sig --name 'xxx'

(be sure not to post anything secret, strace can reveal e.g. privkeys).

Also, is there completely no output, or just some debugging messages? Generating FMTSeq keys takes some time (make sure you're compiling with -O3, it makes quite a difference), but there should be at least a message saying "gathering random bits" or so.

Sir, Thanks for replying. I ran the command that you said. The output is in the attached file. It stops again at the last line

Hm, seems okay. Please wait a bit more, it takes around 1 minute on my laptop. Also, be sure to compile with ./configure CXXFLAGS=-O3. Because the cubehash function (that takes most of the keygen time) is in the compiled source, its speed is directly and very positively affected by the -O3 flag. If nothing happens with -O3 after ~5 minutes, let me know.

screenshot from 2016-06-01 20-08-56 waited for more than 5 min but not showing any output.

Seems you've forgotten to actually rebuild the source. Sorry for not being verbose enough. :]

So:

./configure CXXFLAGS=-O3
make clean
make

should produce a lot faster code.

Please reopen if the problem persists.
