Hi, Does anyone knows there is a way to implement accelerated verification of ECDSA like in this paper: http://www.mathnet.or.kr/mathnet/preprint_file/cacr/2005/cacr2005-28.pdf Specifically instead of generating ECDSA signature with (r,s), I have to generate (R, s). Now R in this case is not the public key. I don't know if OpenSSL currently support this? Regards,
