Types ¶
type ChannelConfigGetter ¶
type ChannelConfigGetter interface {
// GetChannelConfig returns the resources of the channel config
GetChannelConfig(cid string) channelconfig.Resources
}
ChannelConfigGetter enables to retrieve the channel config resources
type ChannelConfigGetterFunc ¶
type ChannelConfigGetterFunc func(cid string) channelconfig.Resources
ChannelConfigGetterFunc returns the resources of the channel config
func (ChannelConfigGetterFunc) GetChannelConfig ¶
func (f ChannelConfigGetterFunc) GetChannelConfig(cid string) channelconfig.Resources
GetChannelConfig returns the resources of the channel config
type ChannelPolicyManagerGetter ¶
type ChannelPolicyManagerGetter interface {
// Returns the policy manager associated to the passed channel
// and true if it was the manager requested, or false if it is the default manager
Manager(channelID string) (policies.Manager, bool)
}
ChannelPolicyManagerGetter is a support interface to get access to the policy manager of a given channel
type ChannelVerifier ¶
type ChannelVerifier struct {
policies.ChannelPolicyManagerGetter
Policy string
}
ChannelVerifier verifies a signature and a message on the context of a channel
func NewChannelVerifier ¶
func NewChannelVerifier(policy string, polMgr policies.ChannelPolicyManagerGetter) *ChannelVerifier
NewChannelVerifier returns a new channel verifier from the given policy and policy manager getter
func (*ChannelVerifier) VerifyByChannel ¶
func (cv *ChannelVerifier) VerifyByChannel(channel string, sd *cb.SignedData) error
VerifyByChannel checks that signature is a valid signature of message under a peer's verification key, but also in the context of a specific channel. If the verification succeeded, Verify returns nil meaning no error occurred. If peerIdentity is nil, then the verification fails.
type DiscoverySupport ¶
type DiscoverySupport struct {
ChannelConfigGetter
Verifier
Evaluator
}
DiscoverySupport implements support that is used for service discovery that is related to access control
func NewDiscoverySupport ¶
func NewDiscoverySupport(v Verifier, e Evaluator, chanConf ChannelConfigGetter) *DiscoverySupport
NewDiscoverySupport creates a new DiscoverySupport
func (*DiscoverySupport) ConfigSequence ¶
func (s *DiscoverySupport) ConfigSequence(channel string) uint64
ConfigSequence returns the configuration sequence of the given channel
func (*DiscoverySupport) EligibleForService ¶
func (s *DiscoverySupport) EligibleForService(channel string, data cb.SignedData) error
Eligible returns whether the given peer is eligible for receiving service from the discovery service for a given channel
func (*DiscoverySupport) SatisfiesPrincipal ¶
func (s *DiscoverySupport) SatisfiesPrincipal(channel string, rawIdentity []byte, principal *msp.MSPPrincipal) error
type Evaluator ¶
type Evaluator interface {
// Evaluate takes a set of SignedData and evaluates whether this set of signatures satisfies the policy
Evaluate(signatureSet []*cb.SignedData) error
}
Evaluator evaluates signatures. It is used to evaluate signatures for the local MSP
type Verifier ¶
type Verifier interface {
// VerifyByChannel checks that signature is a valid signature of message
// under a peer's verification key, but also in the context of a specific channel.
// If the verification succeeded, Verify returns nil meaning no error occurred.
// If peerIdentity is nil, then the verification fails.
VerifyByChannel(channel string, sd *cb.SignedData) error
}
Verifier verifies a signature and a message
