TestSessionKeyString fails with Go 1.18beta1

[alexsaezm]

TestSessionKeyString fails with Go 1.18beta1. The tests works perfectly fine with 1.16 and 1.17.

$ go test -timeout 30s -run ^TestSessionKeyString$ github.com/schollz/pake/v3

This issue appeared in a Fedora package review, but it is not related with the package system.

I would be nice to see croc in Fedora. As I understood, this issue complicates the thing as pake is needed to be packaged before croc. @schollz I wonder, if it is just a problem with tests or with 1.18 pake could do not function correctly?

Thanks for bringing this up @alexsaezm. It seems that Go1.18 now assumes that the point on the curve has been modulo-ed against the order of the underlying field. Will wait to see how this is addressed before addressing here.
