comment How do I convert the definition of E-521 into a curve definition a la Bouncy Castle?
Thanks for the advice! I'll look into it. It may be in the Java version and not yet in the C# version, so I'll possibly just have some conversion to do.

Ah, I think I have found it. If I'm reading this correctly and assuming that BC implemented the basic Weierstrass-form, then I have to implement the Montgomery form myself or convert it to Weierstrass form. Am I reading this correctly? Are there any performance considerations in this?

That makes sense. Unfortunately, it's what we're relegated to without implementing our own ECC. The FpCurve takes in three BigIntegers, q, a, and b. The question is really, how do I map the definition of the curve to these parameters? I'll look in to the Montgomery though, as it seems (according to SafeCurves) to fit our needs as well.
