seems to me that : output_hash.hc22000 is the name of a file where you have stored the actual hash? But the command line is reading it as a hash itself and sees the dot (.) as a separator in the hash (cypher)

Try one of these:

1- name the file with a simple name, like: myhashs.txt or myhash.hash

2- instead of passing the file name, actually paste the hash (number or cipher) directly in the command.

Try it, I hope it helps.
