Hello,
I've noticed that duplicity does not require me the GPG passphrase for
the secret key when doing a differential backup, but it requires the
passphrase for a 'verify'. From the latter I see that my files are
properly encrypted.
Nevertheless, how come duplicity can do a differential backup without
being able to decrypt what has already been backed up? Are the files
metadata (names, timestamps, sizes, ...) stored without encryption?

Fixed 435975 gpg asks for password in 0.6.05, but not in 0.5.18
Hi Kenneth,
thank you for the new version.
Is it sure that bug 435975 is really fixed?
I tried the following command line:
/usr/bin/duplicity --name fixedname --archive-dir
/tmp/duplicity_test/archive --encrypt-key B399F3FD -v9 /tmp/duplic
ity_testdata file:///tmp/duplicity_test/data
The first time (full backup) the backup finished successfully. The
second time a GPG error "Entschlüsselung fehlgeschlagen: Geheimer
Schlüssel ist nicht vorhanden" (english: "decryption failed: Secret key
not available") occured.
I have attached the full log as text file.
Regards
Georg
