I wonder if there is a free program with source that finds symmetric positions of a specific position.

The program simply should get a fen and parameter (same side to move in case that there is no problem because of castling rights or different side to move) and return a symmetric fen

Example:

The program should get the following fen

[D]4k3/8/8/pppppppp/8/8/PPPPPPPP/4K3 w - - 0 1
   ::    :: BK ::    ::
::    ::    ::    ::    
   ::    ::    ::    ::
BP BP BP BP BP BP BP BP
   ::    ::    ::    ::
::    ::    ::    ::    
WP WP WP WP WP WP WP WP
::    ::    WK    ::    


it can return the following fens(when the first is for the same side to move and the second is for different side to move)

[D]3k4/8/8/pppppppp/8/8/PPPPPPPP/3K4 w - - 0 1
   ::    BK    ::    ::
::    ::    ::    ::    
   ::    ::    ::    ::
BP BP BP BP BP BP BP BP
   ::    ::    ::    ::
::    ::    ::    ::    
WP WP WP WP WP WP WP WP
::    :: WK ::    ::    

[D]4k3/pppppppp/8/8/PPPPPPPP/8/8/4K3 b - - 0 1
   ::    :: BK ::    ::
BP BP BP BP BP BP BP BP
   ::    ::    ::    ::
::    ::    ::    ::    
WP WP WP WP WP WP WP WP
::    ::    ::    ::    
   ::    ::    ::    ::
::    ::    WK    ::
