+Generate a prime field, prime order, uniquely generated 192-bit curve, don't ask for input try random values:

 ### Generation methods
 Three different EC curve parameters generation methods are implemented.

  - Can generate curves repeatedly until one satisfies requested properties:
    - `-p/--prime` generates curves until a prime order curve is found.
    - `-k/--koblitz` generates a curve with fixed *A = 0* parameter.
+   - `-u/--unique` generates a uniquely generated curve (with one generator/cyclic group).
 
 ##### Invalid curve generation
  - Generates *invalid* curves for a given curve.
