Does the password obtained via zld_fsextract work for both .bin and .db firmware files?

No. The article notes that the decryption password obtained from tracking `zld_fsextract` parameters works for the .bin file but does not apply to the `536ABHL0C0.db` file. For .db files, the known-plaintext attack method is required instead, using the appropriate absolute path of `system-default.conf` within the archive.
