Hi Angelo, hi all, First of all thanks for making JPBC and publishing it as open-source. I would love to make use of your great work. My first hurdle with your library is that it is not available in the maven central repository. Would you consider publishing your releases to maven central? You will find instructions here: https://central.sonatype.org/pages/ossrh-guide.html I would assist in case you have any questions and strongly believe this would make your library more attractive for other Java...

I am currently trying to implement this paper supposed to generate a random number from Zp or prime group and a hash function H:{0,1}* -> G but I can't find any Zp available in jpbc or pbc cryptography. My current code is as follow: //Check the params, esp number of primes and lambda (bit length of each prime)! TypeA1CurveGenerator parametersGenerator = new TypeA1CurveGenerator( 3, // the number of primes lambda // the bit length of each prime ); PairingParameters params = parametersGenerator.generate();...

I've been working with JPBC for a while. Now I'm stuck in one little problem. I need to receive a String representation of a generated element from G1 group. So I randomly generated (using newRandomElement()) this element g. However, g cannot be converted to BigInteger (Exception: Cannot convert to BigInteger) because at some point it contains "401329,3521518". The receiver gets a String representation of g and then has to instantiate a new Element but it's not possible to do that using a Big Integer...
