Constants ¶
const ( FeatureHA = "ha" // High Availability clustering FeatureKubernetes = "kubernetes" // Kubernetes integration FeatureAWS = "aws" // AWS integration FeatureGCP = "gcp" // GCP integration FeatureTerraform = "terraform" // Terraform provider )
Feature constants for license gating
const DefaultGracePeriod = 7 * 24 * time.Hour // 7 days
DefaultGracePeriod is the default grace period after license expiration
Variables ¶
var ( // ErrLicenseExpired is returned when a license has expired beyond its grace period ErrLicenseExpired = errors.New("license expired") // ErrLicenseInvalid is returned when a license cannot be parsed or verified ErrLicenseInvalid = errors.New("invalid license") // ErrFeatureNotLicensed is returned when attempting to use an unlicensed feature ErrFeatureNotLicensed = errors.New("feature not licensed") // ErrNoLicenseFile is returned when no license file is specified or found ErrNoLicenseFile = errors.New("no license file") )
Functions ¶
func GenerateJWT ¶
func GenerateJWT(claims Claims, privateKey ed25519.PrivateKey) (string, error)
GenerateJWT creates a signed JWT from claims using the provided private key This is primarily used for license generation tooling
func LoadPublicKeyFromFile ¶
LoadPublicKeyFromFile loads a public key from a file This can be used for custom deployments with their own keys
func RequireFeature ¶
RequireFeature validates that a license has a specific feature
Types ¶
type Claims ¶
type Claims struct {
// Standard JWT claims
Issuer string `json:"iss"` // "neuwerk.io"
Subject string `json:"sub"` // License holder identifier
ExpiresAt int64 `json:"exp"` // Expiration timestamp
IssuedAt int64 `json:"iat"` // Issuance timestamp
NotBefore int64 `json:"nbf,omitempty"` // Not valid before timestamp
JTI string `json:"jti,omitempty"` // JWT ID (unique identifier)
// Custom claims
Features []string `json:"features"` // Enabled features: ["ha", "kubernetes"]
CustomerID string `json:"customer_id,omitempty"` // Customer identifier
MaxNodes int `json:"max_nodes,omitempty"` // Max cluster nodes (0 = unlimited)
LicenseType string `json:"license_type,omitempty"` // "trial", "commercial", "enterprise"
}
Claims represents the JWT claims structure for Neuwerk licenses
type License ¶
