gir1.2-gnomekeyring-1.0 binary package in Ubuntu Xenial amd64

 gnome-keyring is a daemon in the session, similar to ssh-agent,
 and other applications can use it to store passwords and other
 sensitive information.
 .
 The program can manage several keyrings, each with its own master
 password, and there is also a session keyring which is never stored to
 disk, but forgotten when the session ends.
 .
 This package provides introspection data for libgnome-keyring. It can
 be used by packages using the GIRepository format to generate dynamic
 bindings.
