Types

type AdminListUsersResult 

type AdminListUsersResult struct {
	Users  []AdminUser `json:"users"`
	Total  int64       `json:"total"`
	Limit  int         `json:"limit"`
	Offset int         `json:"offset"`

Admin listing/get/delete

type AuthEventLogReader added in v0.4.2 

type AuthEventLogReader interface {
	// ListSessionEvents returns session events matching any of the given event types.
	// If userID is empty, returns events for all users.
	ListSessionEvents(ctx context.Context, userID string, eventTypes ...SessionEventType) ([]AuthSessionEvent, error)
}

AuthEventLogReader allows listing session events filtered by event types and optional userID.

type AuthEventLogger 

type AuthEventLogger interface {
	LogSessionEvent(ctx context.Context, e AuthSessionEvent) error
}

type AuthSessionEvent 

type AuthSessionEvent struct {
	OccurredAt time.Time
	Issuer     string
	UserID     string
	SessionID  string
	Event      SessionEventType
	Method     *string
	Reason     *string
	IPAddr     *string
	UserAgent  *string
}

AuthSessionEvent is a best-effort, append-only session lifecycle record intended for external sinks.

ClickHouse schema expectation (see migrations/clickhouse): - issuer, user_id, session_id, event are required - method is typically set for SessionEventCreated - reason is typically set for SessionEventRevoked

type Config 

type Config struct {
	Issuer               string
	IssuedAudiences      []string // JWT audiences - tokens issued will contain ALL of these audiences
	ExpectedAudiences    []string
	AccessTokenDuration  time.Duration
	RefreshTokenDuration time.Duration
	// Session limits
	SessionMaxPerUser int // 0 = unlimited, default 3 if unset by service; eviction is always evict-oldest
	// Optional: if set, used for building absolute URLs (e.g., password reset/verify links).
	// If empty and Issuer is a well-formed URL, NewFromConfig defaults BaseURL to Issuer.
	BaseURL string

	// RegistrationVerification controls registration verification behavior.
	// Valid values: "none", "optional", "required".
	// Empty defaults to "none".
	RegistrationVerification RegistrationVerificationPolicy

	// OrgMode controls multi-organization behavior.
	// Valid values: "single" (default) or "multi".
	OrgMode string

	// Environment is a host-provided runtime mode string used for dev/prod behavior checks.
	// Expected values include "prod"/"production" for production, anything else is treated as non-prod.
	Environment string

	// SolanaNetwork is a host-provided Solana chain selector ("mainnet", "testnet", "devnet").
	// If empty, AuthKit derives a default from Environment.
	SolanaNetwork string

	// Keys can be nil - if nil, authkit auto-discovers keys with this priority:
	// 1. Environment variables (ACTIVE_KEY_ID, ACTIVE_PRIVATE_KEY_PEM, PUBLIC_KEYS)
	// 2. Filesystem /vault/auth/keys.json (External Secrets Operator in K8s)
	// 3. Auto-generated keys in .runtime/authkit/ (development fallback)
	Keys jwtkit.KeySource

	// Providers – identity providers by name ("google", "apple", "github", "discord").
	// Only client id/secret are required; standard scopes are derived from defaults.
	Providers map[string]oidckit.RPConfig
}

Config mirrors the simplicity of go-pkgz/auth: provide issuer, durations, and keys.

type EmailSender 

type EmailSender interface {
	SendVerification(ctx context.Context, email, username string, msg VerificationMessage) error
	SendPasswordResetLink(ctx context.Context, email, username, token string) error

	Get(ctx context.Context, key string) ([]byte, bool, error)
	Set(ctx context.Context, key string, value []byte, ttl time.Duration) error
	Del(ctx context.Context, key string) error
}

EphemeralStore is a minimal key-value interface used for short-lived auth state. Implementations should honor TTL on Set and treat missing keys as (found=false, err=nil).

type Keyset 

type Keyset struct {
	Active     jwtkit.Signer
	PublicKeys map[string]*rsa.PublicKey // kid -> pub
}

Keyset holds the active signer and the public keys exposed via JWKS.

type Options 

type Options struct {
	Issuer               string
	IssuedAudiences      []string // JWT audiences - tokens issued will contain ALL of these audiences
	ExpectedAudiences    []string
	AccessTokenDuration  time.Duration
	RefreshTokenDuration time.Duration
	SessionMaxPerUser    int
	// Optional link building (paths are fixed: /reset and /verify)
	BaseURL string
	// RegistrationVerification controls whether registration verification is disabled,
	// non-blocking, or required.
	RegistrationVerification RegistrationVerificationPolicy

	// OrgMode controls multi-organization behavior.
	// Valid values: "single" or "multi".
	OrgMode string

	// Environment is host-provided runtime mode used for dev/prod behavior checks.
	Environment string
	// SolanaNetwork is host-provided chain selector for SIWS flows.
	SolanaNetwork string
