Submodules

aries_cloudagent.vc.ld_proofs.check module

Validator methods to check for properties without a context.

aries_cloudagent.vc.ld_proofs.check.diff_dict_keys(full: dict, with_missing: dict, prefix: str = None, *, document_loader: Callable[[str, dict], dict], context) → Sequence[str]

Get the difference in dict keys between full and with_missing.

Checks recursively

Parameters:

• full (dict) – The full dict with all keys present
• with_missing (dict) – The dict with possibly keys missing
• prefix (str, optional) – The prefix. Mostly used for internal recursion.

Returns:

List of missing property names in with_missing

Return type:

Sequence[str]

aries_cloudagent.vc.ld_proofs.check.get_properties_without_context(document: dict, document_loader: Callable[[str, dict], dict]) → Sequence[str]

Get the properties from document that don’t have an context definition.

aries_cloudagent.vc.ld_proofs.constants module

JSON-LD, Linked Data Proof and Verifiable Credential constants.

aries_cloudagent.vc.ld_proofs.document_loader module

JSON-LD document loader methods.

class aries_cloudagent.vc.ld_proofs.document_loader.DocumentLoader(profile: aries_cloudagent.core.profile.Profile, cache_ttl: int = 300)

Bases: object

JSON-LD document loader.

load_document(url: str, options: dict)

Load JSON-LD document.

Method signature conforms to PyLD document loader interface

Document loading is processed in separate thread to deal with async to sync transformation.

Bases: object

Domain verification result class.

class aries_cloudagent.vc.ld_proofs.validation_result.ProofResult(*, verified: bool, proof: dict = None, error: Exception = None, purpose_result: aries_cloudagent.vc.ld_proofs.validation_result.PurposeResult = None)

Bases: object

Proof result class.

class aries_cloudagent.vc.ld_proofs.validation_result.PurposeResult(*, valid: bool, error: Exception = None, controller: dict = None)
