git-crypt does not unlock files ...not able to view the file after unlock on MAC

I did lock the files using git-crypt lock and I see they are not readable...when I tried to do git-crypt unlock /path/to/key it exits with out any errors, but not able to see the content of the file..it is in encrypted format...can I decrypt the file with the key I have...

I need to disable the encryption for terraform to work.

FYI...I lost important state files and do not have back up. Please help
