minimum working example for ECC

[davejakenic]

Hello,

I have read the documentation on ECC ( https://pycryptodome.readthedocs.io/en/latest/src/public_key/ecc.html ).
I cannot help myself with it. I would like to compute the following:

I initialize an object G, hiding a cyclic group context (a.k.a., "g,N"), and being the generator of the group.
That is, using random integers j,k in python, I can compute:

G = supercurve("ed25519")
U=j*G
V=k*U
flag = V==j*k*G

Can you give me a minimum actual working code example for the above with pycryptodome?
I don't care what curve is used precisely. It just has to satisfy the CDH assumption; and it would be nice if you give rough advice on the size of j,k and the size of G,U,V, respectively.

Thank you very much in advance!
