The passphrase is read in epg--status-GET_HIDDEN. For gpgsm (same arguments as passed from Emacs, plus --passphrase-fd 0) output is this: $ /usr/bin/gpgsm --no-tty --status-fd 1 --yes --output hello.txt.p7m --p= inentry-mode loopback --passphrase-fd 0 --sign -u XXXXXXXXXXXXXXXX -- hello= .txt 2>/dev/null **** <-- passphrase input [GNUPG:] PROGRESS starting_agent ? 0 0 [GNUPG:] SIG_CREATED S 1 8 00 20231115T195756 XXXXXXXXXXXXXXXXXXXXXXXXXX= XXXXXXXXXXXXXX Note that gpgsm is way less chatty than gpg2. Especially, the passphrase is expected before the first status message appears, and function epg--status-GET_HIDDEN is never called. So this would have to be handled in a different way.
