After descrypt, it's not creating a new nds, like the command -hash

I try all the command, only hash create a new file, and decrypt the file, a message saying that is done appears but not create a new file, it's working on the previous file?

Yes. Here's a line from the readme demonstrating this as intended behavior.

Note: This overwrites the input files, so make backups if you're working on your original, personal dumps.

It sounds like you want to supply a duplicate of your file as the input to prevent the original copy from being overwritten and lost. Personally, I like to duplicate the original file and rename the new copy to denote whether it's going to be encrypted or decrypted, ie; renaming the new copy as filename-dec or filename-enc respectively. Good luck.
