Variables

var AcceptAllPolicy *cb.SignaturePolicyEnvelope

AcceptAllPolicy always evaluates to true

var MarshaledAcceptAllPolicy []byte

MarshaledAcceptAllPolicy is the Marshaled version of AcceptAllPolicy

var MarshaledRejectAllPolicy []byte

MarshaledRejectAllPolicy is the Marshaled version of RejectAllPolicy

var RejectAllPolicy *cb.SignaturePolicyEnvelope

RejectAllPolicy always evaluates to false

Functions

func And

func And(lhs, rhs *cb.SignaturePolicy) *cb.SignaturePolicy

And is a convenience method which utilizes NOutOf to produce And equivalent behavior

func Envelope

func Envelope(policy *cb.SignaturePolicy, identities [][]byte) *cb.SignaturePolicyEnvelope

Envelope builds an envelope message embedding a SignaturePolicy

func FromString

func FromString(policy string) (*common.SignaturePolicyEnvelope, error)

FromString takes a string representation of the policy, parses it and returns a SignaturePolicyEnvelope that implements that policy. The supported language is as follows:

GATE(P[, P])

where:

• GATE is either "and" or "or"
• P is either a principal or another nested call to GATE

A principal is defined as:

ORG.ROLE

where:

• ORG is a string (representing the MSP identifier)
• ROLE takes the value of any of the RoleXXX constants representing the required role

func NOutOf

func NOutOf(n int32, policies []*cb.SignaturePolicy) *cb.SignaturePolicy

NOutOf creates a policy which requires N out of the slice of policies to evaluate to true

func NewPolicyProvider

func NewPolicyProvider(deserializer msp.IdentityDeserializer) policies.Provider

NewProviderImpl provides a policy generator for cauthdsl type policies

func Or

func Or(lhs, rhs *cb.SignaturePolicy) *cb.SignaturePolicy

Or is a convenience method which utilizes NOutOf to produce Or equivalent behavior

func SignedBy

func SignedBy(index int32) *cb.SignaturePolicy

SignedBy creates a SignaturePolicy requiring a given signer's signature

func SignedByAnyAdmin

func SignedByAnyAdmin(ids []string) *cb.SignaturePolicyEnvelope

SignedByAnyAdmin returns a policy that requires one valid signature from a admin of any of the orgs whose ids are listed in the supplied string array

func SignedByAnyClient

func SignedByAnyClient(ids []string) *cb.SignaturePolicyEnvelope

SignedByAnyClient returns a policy that requires one valid signature from a client of any of the orgs whose ids are listed in the supplied string array

func SignedByAnyMember

func SignedByAnyMember(ids []string) *cb.SignaturePolicyEnvelope

SignedByAnyMember returns a policy that requires one valid signature from a member of any of the orgs whose ids are listed in the supplied string array

func SignedByAnyPeer

func SignedByAnyPeer(ids []string) *cb.SignaturePolicyEnvelope

SignedByAnyPeer returns a policy that requires one valid signature from an orderer of any of the orgs whose ids are listed in the supplied string array

func SignedByMspAdmin

func SignedByMspAdmin(mspId string) *cb.SignaturePolicyEnvelope

SignedByMspAdmin creates a SignaturePolicyEnvelope requiring 1 signature from any admin of the specified MSP

func SignedByMspClient

func SignedByMspClient(mspId string) *cb.SignaturePolicyEnvelope

SignedByMspClient creates a SignaturePolicyEnvelope requiring 1 signature from any client of the specified MSP

func SignedByMspMember

func SignedByMspMember(mspId string) *cb.SignaturePolicyEnvelope

SignedByMspMember creates a SignaturePolicyEnvelope requiring 1 signature from any member of the specified MSP

func SignedByMspPeer

func SignedByMspPeer(mspId string) *cb.SignaturePolicyEnvelope

SignedByMspPeer creates a SignaturePolicyEnvelope requiring 1 signature from any peer of the specified MSP
