Thank you. I don't follow all of that, such as deep diving into gnupg/common/sysutils.c:translate_sys2libc_fd , but I do get the answer is: Unsupported (at least at this time).
Could you make whatever notation at dev.gnupg.org is appropriate, please? Summary: --passphrase-fd #, where # >= 3, fails under Windows / DOS %COMSPEC% == unsupported (at this time). So that, with that and this list, web searchers looking to figure out why the described '--passphrase-fd #' isn't working for them, stop chasing their tails? [i.e. it's not user error, it's a Windows (DOS) issue not yet worked around]. ----- It is curious that fd 4 produced the different result of triggering a graphical pinentry. I presume the file open failed and it fell back to that mechanism. And, interesting that under wsl: 'cat HelloWorld.txt | gpg.exe --pinentry-mode loopback --passphrase-fd 4 -c 4< HelloWorld.txt' returned the expected consistent result for fd 3. [with and without --pinentry-mode loopback] > gpg: failed to translate osfhandle 0x00000004 Interesting in that: (1) A call to an .exe file ran 'properly' (under wsl) at all. [Who knew!] (Once I did, seemed worth a try, here.) (2) The surrounding os file redirection services (between cmd.exe and wsl.exe) are inconsistent - wsl.exe side behaviour better operating in the traditional and expected manner, than cmd.exe. > lsb_release -a ; uname -a No LSB modules are available.
