- Group element arithmetics is possible only with the same types of groups and throws `MethodError` when that is violated. For instance, `@ECGroup{P_192}() * @ECGroup{P_256}()` throws an error;
- Group elements are validated during construction, throwing `ArgumentError` for invalid inputs;
- Modular prime group elements are checked to belong in prime group via $g^q = 1$;
- Modular prime group elements are checked to belong in prime group via $g^q = 1$ or with an efficient `jaocbi(g, p) = 1` for quadratic residue groups;
- Elliptic curve points are checked for curve equation satisfaction and cofactor validation;
- The package implements checks to prevent issues with special cases in point addition formulas;
- Exponentiation with $k~ {\rm mod} ~q = 0$ shows warning or throws an error in a strict mode.
