Constants

const PolicyTokenRule = "bacalhau.authn.token" //nolint:gosec

The rule that authentication policies must implement. If the rule returns a token string, the authentication method has succeeded and passed policy, and the token string will be passed to future API calls. If the rule returns nothing, authentication has failed.

This is typically provided by a package `bacalhau.authn` and defined rule `token`. See "challenge_ns_anon.rego" for a minimal example.

Types

type Authentication

type Authentication struct {
	Success bool   `json:"success"`
	Reason  string `json:"reason,omitempty"`
	Token   string `json:"token,omitempty"`
}

Authentication represents the result of a user attempting to authenticate. If Success is true, Token will provide an access token that the user agent should pass to future API calls. If Success is false, Reason will provide a human-readable reason explaining why authentication failed.

func Error

func Error(err error) (Authentication, error)

func Failed

func Failed(reason string) Authentication

type Authenticator

type Authenticator interface {
	provider.Providable

	Authenticate(ctx context.Context, req []byte) (Authentication, error)
	Requirement() Requirement
}

Authenticator accepts HTTP requests for user authentications and returns the result of trying to authenticate the credentials supplied by the user.

type MethodType

type MethodType string
const (
	// An authentication method that provides a challenge string that the user
	// must sign using their private key.
	MethodTypeChallenge MethodType = "challenge"

	// An authentication method that asks the user to supply some credentials.
	MethodTypeAsk MethodType = "ask"
)

type Provider

type Provider = provider.Provider[Authenticator]

Provider maps "method names" to authenticator implementations. A method name is a human-readable string chosen by the person configuring the system that is shown to users to help them pick the authentication method they want to use. There can be multiple usages of the same Authenticator *type* but with different configs and parameters, each identified with a unique method name.

For example, if an implementation wants to allow users to log in with Github or Bitbucket, they might both use an authenticator implementation of type "oidc", and each would appear once on this provider with key / method name "github" and "bitbucket".

type Requirement

type Requirement struct {
	// The type of the method, informing the user agent how to prepare an
	// authentication response.
	Type MethodType `json:"type"`
	// Parameters specific to this authentication type. For example, a list of
	// required information, or minimum acceptable key sizes.
	Params *json.RawMessage `json:"params"`
}

Requirement represents information about how to authenticate using a configured method.
