For those, perhaps it would be nice to just use the constant: "MGF: MGF1ParameterSpec.SHA1" and for anything else, "MGF: MGF1ParameterSpec [digestAlgorithm: ...>". If this is too complicated, then I am ok with the above.

This is doable and probably will be fast if I just keep checking `if (this == MGF1ParameterSpec.SHA1) return "MGF1ParameterSpec.SHA1"` but the code will be quite long. There are 11 constants. Maybe if this class were an enumeration...
