Hi Folks,
I'm developping the DSA Algo:
To sign:
r = (g^k mod p) mod q
s = (k^-1 (H(m) + x*r)) mod q
My question is: When calculating s, we need H(m) and I would like to know
if it must be convert to some kind of type ?
Is it possible for someone to send me a signature (r and s) that is good
using SHA1 as Hash algo, with the plaintext that has been type ? In that
case I will be sure my implementation is good.
Thanks
Best regards,
Hans...
