}

func NewORM

func NewORM(db *sqlx.DB, sessionDuration time.Duration, lggr logger.Logger) ORM

type Session

type Session struct {
	ID        string    `json:"id"`
	LastUsed  time.Time `json:"lastUsed"`
	CreatedAt time.Time `json:"createdAt"`
}

Session holds the unique id for the authenticated session.

func NewSession

func NewSession() Session

NewSession returns a session instance with ID set to a random ID and LastUsed to now.

type SessionReaperConfig

type SessionReaperConfig interface {
	SessionTimeout() models.Duration
	ReaperExpiration() models.Duration
}

type SessionRequest

type SessionRequest struct {
	Email          string `json:"email"`
	Password       string `json:"password"`
	WebAuthnData   string `json:"webauthndata"`
	WebAuthnConfig WebAuthnConfiguration
	SessionStore   *WebAuthnSessionStore
	RequestContext *gin.Context
}

SessionRequest encapsulates the fields needed to generate a new SessionID, including the hashed password.

type User

type User struct {
	Email             string
	HashedPassword    string
	CreatedAt         time.Time
	TokenKey          null.String
	TokenSalt         null.String
	TokenHashedSecret null.String
	UpdatedAt         time.Time
}

User holds the credentials for API user.

func NewUser

func NewUser(email, plainPwd string) (User, error)

NewUser creates a new user by hashing the passed plainPwd with bcrypt.

func (*User) GenerateAuthToken

func (u *User) GenerateAuthToken() (*auth.Token, error)

GenerateAuthToken randomly generates and sets the users Authentication Token.

func (*User) SetAuthToken

func (u *User) SetAuthToken(token *auth.Token) error

SetAuthToken updates the user to use the given Authentication Token.

type WebAuthn

type WebAuthn struct {
	Email         string
	PublicKeyData sqlxTypes.JSONText
}

WebAuthn holds the credentials for API user.

type WebAuthnConfiguration struct {
	RPID     string
	RPOrigin string
}

type WebAuthnSessionStore

type WebAuthnSessionStore struct {
	// contains filtered or unexported fields
}

WebAuthnSessionStore is a wrapper around an in memory key value store which provides some helper methods related to webauthn operations.
