Changing File Permissions in Cygwin (Windows 8)

I tried to change the permissions of my ssh private/public keys in the .ssh directory under Cygwin on Windows 8 and it didn’t work. This seems to be a bug in Cygwin but there is a work around that I found through SuperUser.

chgrp -R Users ~/.ssh

Now all you need to do is run the chmod commands as usual and all should work.

 chmod 644
 chmod 600 id_rsa
