This project is originally forked from https://github.com/gsterjov/go-libsecret[go-libsecret^] due to:

* Lack of response from the developer
* Complete lack of documentation
* Poor, ineffecient, or just plain antipattern design
* Missing functionality

and as such, hopefully this library should serve as a more effective libsecret/SecretService interface.

== Backwards Compatability/Drop-In Replacement Support

Version series `v0.X.X` of this library promises full and non-breaking backwards support of API interaction with the original project. The only changes should be internal optimizations, adding documentation, some file reorganizing, adding Golang module support, etc. -- all transparent from the library API itself.

To use this library as a replacement without significantly modifying your code, you can simply use a `replace` directive:

// TODO: did I do this correctly? I never really use replacements so someone PR if this is incorrect.
.go.mod
[source]
----
// ...
replace (
	github.com/gsterjov/go-libsecret dev => r00t2.io/gosecret v0
)
----

and then run `go mod tidy`.

== New Developer API

Starting from `v1.0.0` onwards, entirely breaking changes can be assumed from the original project.

To use the new version,

[source,go]
----
import (
	`r00t2.io/gosecret/v1`
)
----

To reflect the absolute breaking changes, the module name changes as well from `libsecret` to `gosecret`.

=== Status

The new API is underway, and all functionality in V0 is present. However, it's not "complete". https://github.com/johnnybubonic/gosecret/pulls[PRs^] welcome, of course, but this will be an ongoing effort for a bit of time.

== SecretService Concepts

For reference:

* A `*Service*` allows one to retrieve and operate on/with `*Session*` and `*Collection*` objects.
* A `*Session*` allows one to operate on/with `*Item*` objects (e.g. parsing/decoding/decrypting them).
* A `*Collection*` allows one to retrieve and operate on/with `*Item*` objects.
* An `*Item*` allows one to retrieve and operate on/with `*Secret*` objects.

(`*Secrets*` are considered "terminating objects" in this model, and contain
actual secret value(s) and metadata).

Various interactions are handled by `*Prompts*`.

So the object hierarchy in *theory* looks kind of like this:

----
Service
├─ Session "A"
├─ Session "B"
├─ Collection "A"
│	├─ Item "A.1"
│	│	├─ Secret "A_1_a"
│	│	└─ Secret "A_1_b"
│	└─ Item "A.2"
│		├─ Secret "A_2_a"
│		└─ Secret "A_2_b"
└─ Collection "B"
    ├─ Item "B.1"
    │	├─ Secret "B_1_a"
    │	└─ Secret "B_1_b"
    └─ Item "B.2"
        ├─ Secret "B_2_a"
        └─ Secret "B_2_b"
----

And so on.

In *practice*, however, most users will only have two ``Collection``s:

* a default "system" one named `login` (usually unlocked upon login), and
* a temporary one that may or may not exist, running in memory for the current login session named `session`

== Usage

Full documentation can be found via inline documentation. Either via the https://pkg.go.dev/r00t2.io/gosecret[pkg.go.dev documentation^] or https://pkg.go.dev/golang.org/x/tools/cmd/godoc[`godoc`^] (or `go doc`) in the source root.

However, here's a quick demonstration.

	collectionName string = "login"
	// A label for an Item used in examples below.
	exampleLabel   string = "Some Website Credentials"

func main() {

	var collection *gosecret.Collection

	var itemAttrs map[string]string
	var itemLabel string

	// All interactions with SecretService start with initiating a Service connection.
	if service, err = gosecret.NewService(); err != nil {

	defer service.Close()

	// And unless operating directly on a Service via its methods, you probably need a Collection as well.

		log.Panicln(err)
	}

	/*
		Create a Secret which gets stored in an Item which gets stored in a Collection.
		See the documentation for details.
	*/
	// Incidentally, I believe this is the only exported function/method that does not return an error returner.
	secret = gosecret.NewSecret(
		service.Session,                   // The session associated with this Secret. You're likely fine with the automatically-created *(Service).Session.
		[]byte{},                          // The "parameters". Likely this is an empty byteslice.

	)

	/*

		Do *NOT* store sensitive information in these.
		They're primarily used for searching for Items.
	*/
	itemAttrs = map[string]string{

		"note":     "These keys can be anything you want!",
		"url":      "https://somewebsite.tld/login",

		true,         // Whether to replace an existing item with the same label or not.
	); err != nil {
		log.Panicln(err)
	}

	/*
		Now let's fetch the same Item via its attributes.
		The results are split into locked items and unlocked items.
	*/
	var unlockedItems []*gosecret.Item
	var lockedItems []*gosecret.Item

	if unlockedItems, lockedItems, err = service.SearchItems(itemAttrs); err != nil {
		log.Panicln(err)
	}

	// We should only have one Item that matches the search attributes, and unless the item or collection is locked, ...
	item = unlockedItems[0]
	if itemLabel, err = item.Label(); err != nil {
		log.Panicln(err)
	}
	fmt.Printf("Found item: %v\n", itemLabel)

	// Alternatively if you are unsure of the attributes but know the label of the item you want, you can iterate through them.
	var itemResults []*gosecret.Item

	if itemResults, err = collection.Items(); err != nil {
		log.Panicln(err)
	}

	for idx, i := range itemResults {
		if itemLabel, err = i.Label(); err != nil {
			fmt.Printf("Cannot read label for item at path '%v'\n", i.Dbus.Path())
			continue
		}
		if itemLabel != exampleLabel { // Matching against a desired label - exampleLabel, in this case.
			continue
		}
		fmt.Printf("Found item labeled '%v'! Index number %v at path '%v'\n", itemLabel, idx, i.Dbus.Path())
		fmt.Printf("Password: %v\n", string(i.Secret.Value))
		break
	}
}
----

== Library Hacking

=== Tests

Many functions are consolidated into a single test due to how dependent certain processes are on other objects. However, all functionality should be covered by test cases and the error string will always be passed through the stack to `go test -v` output.

Obviously since this library interacts directly with Dbus (and I don't want to spend the time to mock up an entire Dbus-like interface to test), all tests are integration tests rather than unit tests. Therefore in the event of a failed run, you will need to open e.g. Seahorse or d-feet or some other Dbus/SecretService browser and manually delete the created Secret Service collection. It/they should be easily identified; they use a generated UUID4 string as the collection name and it is highly unlikely that you will see any other collections named as such. If running `go test` with the verbose flag (`-v`), the name and path of the collection will be printed out. If all tests pass, the test collection should be removed automatically.

The same UUID is used for all tests in a test run.

You may be prompted during a test run for a password; you can simply use a blank password for this as it is the password used to protect a collection. This prompt pops up during the creation of a Collection.

Documentation

Overview

Package gosecret is(/was originally) a fork of go-libsecret (see https://github.com/gsterjov/go-libsecret and https://pkg.go.dev/github.com/gsterjov/go-libsecret).

It was forked in order to present bugfixes, actually document the library, conform to more Go-like patterns, and provide missing functionality (as the original seems to be unmaintained). As such, hopefully this library should serve as a more effective libsecret/SecretService interface.

Backwards Compatibility

Version series `v0.X.X` of this library promises full and non-breaking backwards compatibility/drop-in support of API interaction with the original project. The only changes should be internal optimizations, adding documentation, some file reorganizing, adding Golang module support, etc. -- all transparent from the library API itself.

To use this library as a replacement without significantly modifying your code, you can simply use a `replace` directive in your go.mod file: 

// ...
replace (
	github.com/gsterjov/go-libsecret dev => r00t2.io/gosecret v0
)

and then run `go mod tidy`.

Do NOT use the master branch. For anything. I make no promises on the stability of that branch at any given time. New features will be added to V1 branch, and stable releases will be tagged. V0 branch is reserved only for optimization and bug fixes.

New Developer API

Starting from `v1.0.0` onwards, entirely breaking changes can be assumed from the original project. To use the new version, 

import (
	`r00t2.io/gosecret/v1`
)

To reflect the absolute breaking changes, the module name changes as well from `libsecret` to `gosecret`.

SecretService Concepts

For reference:

- A Service allows one to retrieve and operate on/with Session and Collection objects.

- A Session allows one to operate on/with Item objects (e.g. parsing/decoding/decrypting them).

- A Collection allows one to retrieve and operate on/with Item objects.

- An Item allows one to retrieve and operate on/with Secret objects.

(Secrets are considered "terminating objects" in this model, and contain actual secret value(s) and metadata).

Various interactions are handled by Prompts.

So the object hierarchy in THEORY looks kind of like this: 

Service
├─ Session "A"
├─ Session "B"
├─ Collection "A"
│	├─ Item "A.1"
│	│	├─ Secret "A_1_a"
│	│	└─ Secret "A_1_b"
│	└─ Item "A.2"
│		├─ Secret "A_2_a"
│		└─ Secret "A_2_b"
└─ Collection "B"
	├─ Item "B.1"
	│	├─ Secret "B_1_a"
	│	└─ Secret "B_1_b"
	└─ Item "B.2"
		├─ Secret "B_2_a"
		└─ Secret "B_2_b"

And so on. In PRACTICE, however, most users will only have two Collection items (a default "system" one named "login", which usually is unlocked upon login, and a temporary one that may or may not exist, running in memory for the current login session named `session`).

Usage

Functions

func NewErrors added in v1.0.0 

func NewErrors(errs ...error) (err error)

NewErrors returns a new MultiError based on a slice of error.Error (errs). Any nil errors are trimmed. If there are no actual errors after trimming, err will be nil.

func TranslateError added in v1.0.0 

func TranslateError(ssErr SecretServiceErrEnum) (ok bool, err error)

TranslateError translates a SecretServiceErrEnum into a SecretServiceError. If a matching error was found, ok will be true and err will be the matching SecretServiceError. If no matching error was found, however, then ok will be false and err will be ErrUnknownSecretServiceErr.

Types

type Collection 

type Collection struct {
	*DbusObject
	// contains filtered or unexported fields
}

Collection is an accessor for libsecret collections, which contain multiple Secret Item items. Reference: https://developer-old.gnome.org/libsecret/0.18/SecretCollection.html https://specifications.freedesktop.org/secret-service/latest/ch03.html

func NewCollection 

func NewCollection(service *Service, path dbus.ObjectPath) (coll *Collection, err error)

NewCollection returns a pointer to a Collection based on a Service and a Dbus path. You will almost always want to use Service.GetCollection instead.

func (*Collection) CreateItem 

func (c *Collection) CreateItem(label string, attrs map[string]string, secret *Secret, replace bool, itemType ...string) (item *Item, err error)

CreateItem returns a pointer to an Item based on a label, some attributes, a Secret, whether any existing secret with the same label should be replaced or not, and the optional itemType.

itemType is optional; if specified, it should be a Dbus interface (only the first element is used). If not specified, the default DbusDefaultItemType will be used. The most common itemType is DbusDefaultItemType and is the current recommendation. Other types used are: 

org.gnome.keyring.NetworkPassword
org.gnome.keyring.Note

These are libsecret schemas as defined at https://gitlab.gnome.org/GNOME/libsecret/-/blob/master/libsecret/secret-schemas.c (and bundled in with libsecret). Support for adding custom schemas MAY come in the future but is unsupported currently.

func (*Collection) Created added in v1.0.0 

func (c *Collection) Created() (created time.Time, err error)

Created returns the time.Time of when a Collection was created.

func (*Collection) Delete 

func (c *Collection) Delete() (err error)

Delete removes a Collection. While *technically* not necessary, it is recommended that you iterate through Collection.Items and do an Item.Delete for each item *before* calling Collection.Delete; the item paths are cached as "orphaned paths" in Dbus otherwise if not deleted before deleting their Collection. They should clear on a reboot or restart of Dbus (but rebooting Dbus on a system in use is... troublesome).

func (*Collection) Items 

func (c *Collection) Items() (items []*Item, err error)

Items returns a slice of Item pointers in the Collection.

func (*Collection) Label added in v1.0.0 

func (c *Collection) Label() (label string, err error)

Label returns the Collection label (name).

func (*Collection) Locked 

func (c *Collection) Locked() (isLocked bool, err error)

Locked indicates if a Collection is locked (true) or unlocked (false).

func (*Collection) Modified added in v1.0.0 

func (c *Collection) Modified() (modified time.Time, isChanged bool, err error)

Modified returns the time.Time of when a Collection was last modified along with a boolean that indicates if the collection has changed since the last call of Collection.Modified.

Note that when calling NewCollection, the internal library-tracked modification time (Collection.lastModified) will be set to the latest modification time of the Collection itself as reported by Dbus rather than the time that NewCollection was called.

func (*Collection) PathName added in v1.0.0 

func (c *Collection) PathName() (realName string)

PathName returns the "real" name of a Collection. In some cases, the Collection.Label may not be the actual *name* of the collection (i.e. the label is different from the name used in the Dbus path). This is a thin wrapper around simply extracting the last item from the Collection.Dbus.Path().

func (*Collection) Relabel added in v1.0.0 

func (c *Collection) Relabel(newLabel string) (err error)

Relabel modifies the Collection's label in Dbus.

func (*Collection) SearchItems deprecated 

func (c *Collection) SearchItems(profile string) (items []*Item, err error)

SearchItems searches a Collection for a matching profile string. It's mostly a carry-over from go-libsecret, and is here for convenience. IT MAY BE REMOVED IN THE FUTURE.

I promise it's not useful for any other implementation/storage of SecretService whatsoever.

Deprecated: Use Service.SearchItems instead.

type CollectionInitFlag added in v1.0.0 

type CollectionInitFlag int

CollectionInitFlag is a flag for Collection.SearchItems and Collection.Items. 

const (
	FlagCollectionNone CollectionInitFlag = iota
	FlagCollectionLoadItems
)

type ConnPathCheckResult added in v1.0.0 

type ConnPathCheckResult struct {
	// ConnOK is true if the dbus.Conn is valid.
	ConnOK bool `json:"conn"`
	// PathOK is true if the Dbus path given is a valid type and value.
	PathOK bool `json:"path"`
}

ConnPathCheckResult contains the result of validConnPath.

type DbusObject added in v1.0.0 

type DbusObject struct {
	// Conn is an active connection to the Dbus.
	Conn *dbus.Conn `json:"-"`
	// Dbus is the Dbus bus object.
	Dbus dbus.BusObject `json:"-"`
}

DbusObject is a base struct type to be anonymized by other types.

type Item 

type Item struct {
	*DbusObject
	// Secret is the corresponding Secret object.
	Secret *Secret `json:"secret"`
	// contains filtered or unexported fields
}

Item is an entry in a Collection that contains a Secret. https://developer-old.gnome.org/libsecret/0.18/SecretItem.html https://specifications.freedesktop.org/secret-service/latest/re03.html

NewItem returns a pointer to an Item based on Collection and a Dbus path.

func (*Item) Attributes added in v1.0.0 

func (i *Item) Attributes() (attrs map[string]string, err error)

Attributes returns the Item's attributes from Dbus.

func (*Item) Created added in v1.0.0 

func (i *Item) Created() (created time.Time, err error)

func (*Item) Modified added in v1.0.0 

func (i *Item) Modified() (modified time.Time, isChanged bool, err error)

Modified returns the time.Time of when an Item was last modified along with a boolean that indicates if the collection has changed since the last call of Item.Modified.

Note that when calling NewItem, the internal library-tracked modification time (Item.lastModified) will be set to the latest modification time of the Item itself as reported by Dbus rather than the time that NewItem was called.

func (*Item) ModifyAttributes added in v1.0.0 

func (i *Item) ModifyAttributes(replaceAttrs map[string]string) (err error)

ModifyAttributes modifies the Item's attributes in Dbus. This is similar to Item.ReplaceAttributes but will only modify the map's given keys so you do not need to provide the entire attribute map. If you wish to remove an attribute, use the value "" (empty string). If you wish to explicitly provide a blank value/empty string, use the constant gosecret.ExplicitAttrEmptyValue.

This is more or less a convenience/wrapper function around Item.ReplaceAttributes.

func (*Item) Relabel added in v1.0.0 

func (i *Item) Relabel(newLabel string) (err error)

Relabel modifies the Item's label in Dbus.

func (*Item) ReplaceAttributes added in v1.0.0

	/*
		Parameters are "algorithm dependent parameters for secret value encoding" - likely this will just be an empty byteslice.
		Refer to Session for more information.
	*/
	Parameters []byte `json:"params"`
	// Value is the secret's content in []byte format.
	Value SecretValue `json:"value"`
	// ContentType is the MIME type of Value.
	ContentType string `json:"content_type"`
	// contains filtered or unexported fields
}

Secret is the "Good Stuff" - the actual secret content. https://developer-old.gnome.org/libsecret/0.18/SecretValue.html https://specifications.freedesktop.org/secret-service/latest/re03.html https://specifications.freedesktop.org/secret-service/latest/ch14.html#type-Secret

	EnumErrIsLocked
	EnumErrNoSuchObject
	EnumErrAlreadyExists
	EnumErrInvalidFileFormat
)

		This is what should be displayed to users, and is returned by SecretServiceError.Error.
	*/
	ErrDesc string `json:"desc"`
}

SecretServiceError is a translated error from SecretService API. See https://developer-old.gnome.org/libsecret/unstable/libsecret-SecretError.html#SecretError and ErrSecretService* errors.

func (SecretServiceError) Error added in v1.0.0 

func (e SecretServiceError) Error() (errStr string)

Error returns the string format of the error; this is necessary to be considered a valid error interface.

type SecretValue added in v1.0.0 

type SecretValue []byte

SecretValue is a custom type that handles JSON encoding/decoding a little more easily.

func (*SecretValue) MarshalJSON added in v1.0.0 

func (s *SecretValue) MarshalJSON() (b []byte, err error)

MarshalJSON converts a SecretValue to a JSON representation. For compat reasons, the MarshalText is left "unmolested" (i.e. renders to a Base64 value). I don't bother with an UnmarshalJSON because it makes exactly 0 sense to unmarshal due to runtime and unexported fields in Secret.

	*DbusObject
	// Session is a default Session initiated automatically.
	Session *Session `json:"-"`
}

func (*Service) CreateCollection 

func (s *Service) CreateCollection(label string) (collection *Collection, err error)

CreateCollection creates a new Collection (keyring) via a Service with the name specified by label and returns the new Collection. It is a *very* thin wrapper around Service.CreateAliasedCollection, but with a blank alias.

func (*Service) GetCollection added in v1.0.0 

func (s *Service) GetCollection(name string) (c *Collection, err error)

GetCollection returns a single Collection based on the name (name can also be an alias). It's a helper function that avoids needing to make multiple calls in user code.

func (*Service) GetSecrets added in v1.0.0 

func (s *Service) GetSecrets(itemPaths ...dbus.ObjectPath) (secrets map[dbus.ObjectPath]*Secret, err error)

func (s *Service) ReadAlias(alias string) (collection *Collection, err error)

ReadAlias allows one to fetch a Collection based on an alias name. An ErrDoesNotExist will be raised if the alias does not exist. You will almost assuredly want to use Service.GetCollection instead; it works for both alias names and real names.

func (*Service) SearchItems added in v1.0.0 

func (s *Service) SearchItems(attributes map[string]string) (unlockedItems []*Item, lockedItems []*Item, err error)

SearchItems searches all Collection objects and returns all matches based on the map of attributes.

func (*Service) SetAlias added in v1.0.0 

func (s *Service) SetAlias(alias string, objectPath dbus.ObjectPath) (err error)
