fdroidclient now uses SHA256 fingerprints internally, and they are shown in
the repo details view. This changes the digest algorithm to SHA256 and
changes the format to match what is shown in the repo details view.
This assumes that the smartcard is already setup with a signing key. init
does not generate a key on the smartcard, and skips genkey() if things are
configured to use a smartcard.
This also does not touch APK signing because that is a much more elaborate
question, since each app is signed by its own key.
These options are needed to configure Java's keytool and jarsigner to use
a Hardware Security Module aka HSM aka smartcard. The defaults provided
are meant to make things work as easily as possible.
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.
Just dropping this apk entry temporarily caused an old version of the
app to appear on the wiki as a failing build. (only for one cycle after
the archiving happened). Moving it to the archived apks list ought to
resolve that problem.
