Issuer string `json:"issuer,omitempty"`
IssuanceDate string `json:"issuanceDate,omitempty"`
ValidFrom string `json:"validFrom,omitempty"`
ExpirationDate string `json:"expirationDate,omitempty"`
CredentialSubject json.RawMessage `json:"credentialSubject,omitempty"`
CredentialStatus CredentialStatus `json:"credentialStatus,omitempty"`
Proof Proof `json:"proof,omitempty"`
}
Credential represents a verifiable credential.
type CredentialStatus ¶

StatusPurpose string `json:"statusPurpose,omitempty"`
StatusListIndex uint `json:"statusListIndex,omitempty"`
StatusListCredential string `json:"statusListCredential,omitempty"`
}
CredentialStatus represents the status of the verifiable credential.
type Issuer ¶
type Issuer struct {
// contains filtered or unexported fields
}
Issuer issues various Verifiable Credentials.
func (*Issuer) CreateBitstringStatusListVC ¶
type Proof ¶
type Proof struct {
ProofOptions
ProofValue string `json:"proofValue,omitempty"`
}
Proof contains the signed proof value and options.
func CreateProof ¶
func CreateProof(unsecuredDocument Credential, options ProofOptions, privateKey *ecdsa.PrivateKey, ldProcessor *ld.JsonLdProcessor, ldOptions *ld.JsonLdOptions) (Proof, error)
CreateProof creates a proof for a document using ecdsa-rdfc-2019.
type ProofOptions ¶

}
ProofOptions contains the options for generating a proof.
type ProofOptionsWithContext ¶
type ProofOptionsWithContext struct {
Context []string `json:"@context,omitempty"`
ProofOptions
}
proofOptionsWithContext contains the proof options with the context. this is used for canonicalization.
type VINSubject ¶
