Migrating from libgnome-keyringIntroductionConceptually, libgnome-keyring and libsecret are fairly similar. Both
have keyrings, items, and ways to store and retrieve passwords. In both
cases items have attributes. The keys and values of attributes are used
to lookup a password that was stored.There is a
simple password API for storing and retrieving passwords
which is the easiest and recommended way to store passwords. And then
there is a more complicated API which models all the various collections
and items, along with all the possible actions that can be performed on them.libsecret uses the
Secret Service DBus API
to communicate with gnome-keyring-daemon, and as such exposes features
based on that DBus API.libsecret has been designed to be threadsafe, and uses the 'GDBus'
code in gio to accomplish this.Keyrings are called 'collections' in libsecret.See the relevant section for specifics about how to port the
libgnome-keyring functions or symbols in your project.API conversionHere are some clues on how to migrate various libgnome-keyring
API functions and their logical equivalents in libsecret.Item attributesRemember that attributes are not, and never have been stored in
an encrypted fashion. They are not part of the 'secret', but instead
are a way to lookup a secret item.All attributes in libsecret are stored as strings. Sets of attributes
are represented by #GHashTables and the keys and values of
these hash tables are strings.libsecret is far more focused on schemas,
and encourages users to define a #SecretSchema for their password storage.
The schema defines which attributes are allowed an item. Each schema has
a name which is usually a dotted string (eg: org.gnome.MyProject.Password).
This schema name is stored internally in the item attributes.Schemas define whether an attribute should look like an integer,
a boolean, or a free-form string. These types are used when validating
the attribute values, even though the attribute values are stored and
matched as strings. Since attribute values are used primarily
for lookup of items it's important that the string representations of
integers and booleans are always identical. Boolean values are stored
as the strings true and false.
Integer values are stored in decimal, with a preceding negative sign
for negative integers. libsecret facilitates this using the
secret_attributes_build() and secret_attributes_buildv() functions.Attributes are meant to be used for lookup of items; they're not
designed to be used as a generic key/value database. Although you can
force libsecret to do the latter, it's better to store your account
information elsewhere if possible, and use libsecret to store the password
or other secret.Replacements for related libgnome-keyring functions and types

Working with schemaslibsecret is far more focused on schemas, and encourages users to
define a #SecretSchema for their password storage. The schema defines
which attributes are allowed an item. Each schema has a name which
is usually a dotted string (eg: org.gnome.MyProject.Password).
This name is stored in the item attributes. The schema name is also
used when looking up an item, to make sure that the stored schema
matches that used during the lookup. If you wish to lookup items that
were stored by libgnome-keyring, you should specify the
%SECRET_SCHEMA_DONT_MATCH_NAME flag in the schema so that the schema
name is not matched, since it was not stored by libgnome-keyring.Schemas define whether an attribute should look like an integer,
a boolean, or a free-form string. These types are used when validating
the attribute values stored, even though the attribute values are
stored and matched as strings.Replacements for related libgnome-keyring functions and types

Storing passwords and itemsIt's encouraged to use a #SecretSchema when storing items and
passwords.By default most ways of storing an item will now overwrite
another item with the same attributes in the same keyring. To manually
control this behavior use the secret_item_create().Replacements for related libgnome-keyring functions and types

Searching for passwords and itemsIn general libsecret tries not to unlocking keyrings
where not necessary. Many search methods only return one item or
password that matches, preferring already unlocked items, and recently stored
items.Attributes are meant to be used for lookup of items; they're not
designed to be used as a generic key/value database. Although you can
force libsecret to do the latter, it's better to store your account
information elsewhere if possible, and use libsecret to store the password
or other secret. Because of this many search methods return just the
password or secret.Replacements for related libgnome-keyring functions and types

Keyring managementIn libsecret keyrings are called 'collections'. This is the same
lingo as the underlying Secret Service DBus API. Keyrings are no longer
identified by simple keyring names. Normally applications just use the
default keyrings and these are identified by the aliases
%SECRET_COLLECTION_DEFAULT and %SECRET_COLLECTION_SESSION. It is also

Locking and unlockingIn libsecret you can unlock items directly, and the result is
(with gnome-keyring daemon) that the enclosing collection will be unlocked.It is no longer possible to pass a password to unlock keyrings.
These are automatically prompted for.Replacements for related libgnome-keyring functions and types

Non-pageable memorylibsecret no longer provides a full API for using non-pageable
memory. Use the equivalent API in the Gcr library.You can request that passwords are returned in non-pageable
memory by using the secret_password_lookup_nonpageable_sync() and
secret_password_lookup_nonpageable_finish() functions.

non-pageable memory, unless the system doesn't support this.Replacements for related libgnome-keyring functions and types

Errors and cancellationlibsecret uses standard the standard #GCancellable idiom
to cancel operations.It is not necessary to check whether the keyring daemon is
available before using it. It is started automatically.Errors are returned as standard #GError in the usual way.
There are fewer errors that are worth handling in an intelligent way,
exceptions are in the #SecretError enumeration. It is not recommended
to display any #GError message returned by libsecret to the user. Most
of the possible errors are DBus communication problems or similar.Replacements for related libgnome-keyring functions and types
