    wallet_handle: IndyHandle, 
    issuer_did: &str, 
    schema_json: &str, 
    tag: &str,

Create credential definition entity that encapsulates credentials issuer DID, credential schema, secrets used for signing credentials and secrets used for credentials revocation.

Credential definition entity contains private and public parts. Private part will be stored in the wallet. Public part will be returned as json intended to be shared with all anoncreds workflow actors usually by publishing CRED_DEF transaction to Indy distributed ledger.

It is IMPORTANT for current version GET Schema from Ledger with correct seq_no to save compatibility with Ledger.

Arguments

  • issuer_did: a DID of the issuer signing cred_def transaction to the Ledger
  • schema_json: credential schema as a json
  • tag: allows to distinct between credential definitions for the same issuer and schema
  • signature_type: credential definition type (optional, 'CL' by default) that defines credentials signature and revocation math. Supported types are:
    • 'CL': Camenisch-Lysyanskaya credential signature type
  • config_json: (optional) type-specific configuration of credential definition as json:
    • 'CL':
      • support_revocation: whether to request non-revocation credential (optional, default false)

Returns

  • cred_def_id: identifier of created credential definition
  • cred_def_json: public part of created credential definition
