FDroidPopen() does not have a way to send to stdin, so we will use the
password file for now. In the long run, at least the keypass should always
be sent via stdin rather than via a file. Ideally, storepass would be too,
but if they are different, then storepass is less important.
Any process can read the process table, and can therefore see the entire
command line of any other process. That means its a bad idea to ever put
passwords as part of a command line. Python is executing keytool and
jarsigner command lines here, so now instead of putting the password on the
command line, a file is passed instead with suitable file permissions.
This should reduce the exposure a lot. But still, sensitive passwords
should not be written to any text file.
This change requires OpenJDK-7 since the :file option to -storepass and
-keypass was only added in Java 7's keytool and jarsigner.
