Ok, i found a similar issue in gnupg here from this user:

https://bugs.g10code.com/gnupg/issue940

its exactly as described - adding "< /dev/null" to the end solves the problem.

But as the user suggested why does --batch does not take care of it? I saw that it is "expected from unix" programs to behave like this - but what about windows? there is no dev null piping - at least there should be an option because users expect that --batch will work automatically.

Furthermore there is still the issue that even with /dev/null status-fd does not tell me its a detached signature file it just asks for a public key first.

Thanks
