Hi All,
Can I do symmetric encryption non-interactively using gpg?
gpg -batch -ca doesn't seem to work as the key cannot be provided in some file or command line.
Tried writing a expect script, #!/usr/bin/expect -d -f #
set timeout -1 set send_slow {1 .1} set send_human {.1 .3 1 .05 2} spawn gpg -q -o message.enc -ca message match_max 100000 expect -exact "Enter passphrase: " send -- "ab\r" expect -exact "\r \rRepeat passphrase: " send -- "ab\r" expect eof
This script works sometimes, hangs mostly after first/second passphrase has been sent. Tried "send -s/h" but they also fail. What's wrong? Am I missing something?
Also if the expect script can read the input from stdin and write encrypted output to stdout, it would be great. Any help/suggestion is appreciated. I would summarize to the list.
Thanks, Anshul
