Constants

const Domain = "credential"

Domain defines the domain for the credential package.

Variables

var ValidPurposes = []Purpose{
	ApplicationPurpose,
	IngressPurpose,
	EgressPurpose,
}

ValidPurposes are the set of all credential Purposes.

Types

type Certificate

type Certificate interface {
	Credential
	Certificate() []byte
	Private() PrivateKey
}

Certificate is a credential containing a certificate and the private key for the certificate.

type Credential

type Credential interface {
	boundary.Entity
	Secret() SecretData
}

Credential is an entity containing secret data.

type Dynamic

type Dynamic interface {
	Credential
	GetSessionId() string
	Library() Library
	Purpose() Purpose
}

Dynamic is a credential generated by a library for a specific session.

type Issuer

type Issuer interface {
	// Issue issues dynamic credentials for a session from the requested
	// libraries and for the requested purposes. The sessionId must be a
	// valid sessionId. The SourceId in each request must be the public id
	// of a library the Issuer can issue credentials from.
	//
	// If Issue encounters an error, it returns no credentials and revokes
	// any credentials issued before encountering the error.
	Issue(ctx context.Context, sessionId string, requests []Request) ([]Dynamic, error)
}

Issuer issues dynamic credentials.

type KeyPair

type KeyPair interface {
	Credential
	Username() string
	Private() PrivateKey
}

KeyPair is a credential containing a username and a private key.

type Library

type Library interface {
	boundary.Resource
	GetStoreId() string
	CredentialType() Type
}

A Library is a resource that provides credentials that are of the same type and access level from a single store.

type Password

type Password string

Password represents a secret password.

func (Password) GoString

func (s Password) GoString() string

GoString returns a string with the password redacted.

func (Password) MarshalJSON

func (s Password) MarshalJSON() ([]byte, error)

MarshalJSON returns a JSON-encoded string with the password redacted.

func (Password) String

func (s Password) String() string

String returns a string with the password redacted.

type PrivateKey

type PrivateKey []byte

PrivateKey represents a secret private key.

func (PrivateKey) GoString

func (s PrivateKey) GoString() string

GoString returns a string with the private key redacted.

func (PrivateKey) MarshalJSON

func (s PrivateKey) MarshalJSON() ([]byte, error)

MarshalJSON returns a JSON-encoded byte slice with the private key redacted.

func (PrivateKey) String

func (s PrivateKey) String() string

String returns a string with the private key redacted.

type Purpose

type Purpose string

Purpose is the purpose of the credential.

const (
	// ApplicationPurpose is a credential used for application specific
	// purposes. Application credentials are returned to the user.
	ApplicationPurpose Purpose = "application"

	// IngressPurpose is a credential used by a boundary worker to secure
	// the connection between the user and the worker. Ingress credentials
	// are never returned to the user.
	IngressPurpose Purpose = "ingress"

	// EgressPurpose is a credential used by a boundary worker to secure
	// the connection between the worker and the endpoint. Egress
	// credentials are never returned to the user.
	EgressPurpose Purpose = "egress"
)

Credential purpose values.

func (Purpose) String

func (p Purpose) String() string

type Request

type Request struct {
	SourceId string
	Purpose  Purpose
}

A Request represents a request for a credential from the SourceId for the given purpose. For dynamic credentials, the SourceId is the PublicId of a credential library.

type Revoker

type Revoker interface {
	// Revoke revokes the dynamic credentials issued for sessionid.
	Revoke(ctx context.Context, sessionId string) error
}

Revoker revokes dynamic credentials.

type SecretData

type SecretData interface{}

SecretData represents secret data.

type Store

type Store interface {
	boundary.Resource
	GetScopeId() string
}

A Store is a resource that can store, retrieve, and potentially generate credentials of differing types and access levels. It belongs to a scope and must support the principle of least privilege by providing mechanisms to limit the credentials it can access to the minimum necessary for the scope it is in.

type Type

type Type string

Type is the type of credential provided by a library.

const (
	UnspecifiedType  Type = "unspecified"
	UserPasswordType Type = "user_password"
)

Credential type values.

type UserPassword

type UserPassword interface {
	Credential
	Username() string
	Password() Password
}

UserPassword is a credential containing a username and a password.
