Types

type BasicProof

type BasicProof struct {
	Type   string `json:"@type"`
	Issuer string `json:"issuer"`
	HIndex string `json:"h_index"`
	HValue string `json:"h_value"`
}

BasicProof is basic proof for Iden3Claim

type CredentialStatus

type CredentialStatus struct {
	ID   string               `json:"id"`
	Type CredentialStatusType `json:"type"`
}

CredentialStatus contains type and revocation Url

type CredentialStatusType

type CredentialStatusType string

CredentialStatusType type for understanding revocation type

const SparseMerkleTreeProof CredentialStatusType = "SparseMerkleTreeProof"

SparseMerkleTreeProof is CredentialStatusType

type Iden3Credential

type Iden3Credential struct {
	ID                string                 `json:"id"`
	Context           []string               `json:"@context"`
	Type              []string               `json:"@type"`
	Expiration        time.Time              `json:"expiration,omitempty"`
	Updatable         bool                   `json:"updatable"`
	Version           uint32                 `json:"version"`
	RevNonce          uint64                 `json:"rev_nonce"`
	CredentialSubject map[string]interface{} `json:"credentialSubject"`
	CredentialStatus  *CredentialStatus      `json:"credentialStatus,omitempty"`
	CredentialSchema  struct {
		ID   string `json:"@id"`
		Type string `json:"type"`
	} `json:"credentialSchema"`
	Proof interface{} `json:"proof,omitempty"`
}

Iden3Credential is struct that represents claim json-ld document

type MTP

type MTP struct {
	Type      string     `json:"@type,omitempty"`
	Existence bool       `json:"existence"`
	Siblings  []*mt.Hash `json:"siblings"`
	NodeAux   *struct {
		HIndex string `json:"h_index,omitempty"`
		HValue string `json:"h_value,omitempty"`
	} `json:"node_aux,omitempty"`
}

MTP is merkle tree mtp but in lower case and with type

type MTPProof

type MTPProof struct {
	BasicProof
	State struct {
		TxID               *string `json:"tx_id,omitempty"`
		BlockTimestamp     *int    `json:"block_timestamp,omitempty"`
		BlockNumber        *int    `json:"block_number,omitempty"`

		ClaimsTreeRoot     *string `json:"claims_tree_root,omitempty"`
		RevocationTreeRoot *string `json:"revocation_tree_root,omitempty"`
		Value              *string `json:"value,omitempty"`
		Status             string  `json:"status,omitempty"`
	} `json:"state"`

	Mtp MTP `json:"mtp"`
}

MTPProof JSON-LD merkle tree proof

type ProofPurpose

type ProofPurpose string

ProofPurpose is alias for string, represents proof purpose

const (
	// ProofPurposeAuthentication is a proof for authentication
	ProofPurposeAuthentication ProofPurpose = "Authentication"
)

type SignatureProof

type SignatureProof struct {
	BasicProof

	Created            int64    `json:"created"`
	IssuerMTP          MTPProof `json:"issuer_mtp"`
	VerificationMethod string   `json:"verification_method"`
	ProofValue         string   `json:"proof_value"`
	ProofPurpose       string   `json:"proof_purpose"`
}

SignatureProof is proof that contains signature of content
