calculate v s fields from AuthLogonChallenge

well im not sure if this is posible but i want to ask for sure if i can reverse the process of the creation of this 2 values that generate the uint8_t B[32]:confused::confused::confused:

================================================
b.SetRand(19 * 8);
BigNumber gmod = g.ModExp(b, N);
B = ((v * 3) + gmod) % N;
================================================

No, if you could reverse the process of SRP protocol using simple maths it wouldn't be a SECURE REMOTE PASSWORD protocol.

Hah.

Technically you can reverse it. SRP6a doesn't rely (entirely, at least) on security through obscurity. It's not practical though as it will involve arithmetic which would take millions of years to work out.
