Yes, rpm always asks... And yes, expect knows what to do:
#!/usr/bin/expect
set p ""
set f [lindex $argv 0]
spawn rpm --resign $f
expect "Enter pass phrase:"
send -- "$p\r"
expect eof

The other way; Use perl (
http://search.cpan.org/~nanardon/RPM4-0.20/lib/RPM4.pm). RPM4 also knows 
how to do it...
