Functions

func AppendSignerIfNeed

func AppendSignerIfNeed(signers []types.Signer, controller string, msg *types.Did) []types.Signer

func NewMsgServerImpl

func NewMsgServerImpl(keeper Keeper) types.MsgServer

NewMsgServerImpl returns an implementation of the MsgServer interface for the provided Keeper.

func VerifyDidDeactivate

func VerifyDidDeactivate(metadata *types.Metadata, id string) error

Check the Deactivate status of DID

func VerifyIdentitySignature

func VerifyIdentitySignature(signer types.Signer, signatures []*types.SignInfo, signingInput []byte) (bool, error)

Ref 1: The current implementatition takes in the verification key and checks if that belongs to EITHER of the DID controllers. If so, then the signature is valid, which is an approach as opposed to the earlier implementation where all the signatures of all DIDs present in DID controller were expected. This needs to be verified. Link to DID Controller Spec: https://www.w3.org/TR/did-core/#did-controller
