Hi, I need to create a passphrased key in a shell script, and while
testing it in a console it's still asking for the passphrase. Any way
to do that easily?
$ echo -e "MyStrongPassword\nMyStrongPassword" | tarsnap-keymgmt
--outkeyfile outkeyfile -w -r -d --nuke --passphrased keyfile
Please enter passphrase for keyfile encryption:
Ok, after reading the source code I think I got it... tarsnap-keymgmt
attempts to open /dev/tty no matter what and failing that reads from
standard input. So running the pipeline above from cron or similar
should work, since it has no tty open.
