Another solution would be to use the 'command-fd' switch. Then
all input from the keyboard is redirected to the file descriptor
you specify for the command. For example:

gpg --status-fd=2 --command-fd=23 -c foo

Then all input would be read from fd 23 which was created by
a pipe call. You've to watch for the 'status-fd' messages to
send the correct strings.

[GNUPG:] GET_HIDDEN passphrase.enter

This is the string GnuPG will output if a passphrase is needed.

If you want a more elegant solution you should use GPGME.
