Standards and Protocols
Technical summary of the standards and protocols supported by the cloud agent
Secure Channel
| Description | |
|---|---|
DIDComm V1 | DIDComm V1 over HTTP/s is used by the cloud agent to transmit and receive E2EE messages (basic messages, credential exchanges, proof exchanges, etc). |
Credential & Presentation Formats
| Description | |
|---|---|
Anoncreds V1 | The cloud agent supports issuance and presentation of credentials following the Hyperledger AnonCreds Specification v1.0. Anoncreds credentials have many privacy-preserving capabilities such as blinded holder bindings, zero-knowledge proofs and selective disclosure. |
W3C VCs/VPs V1 | The cloud agent supports issuance and presentation of W3C credentials following the W3C Verifiable Credentials Data Model v1.1 spec, using LD-Proofs (JSON Linked Data Proofs). |
Credential & Proof Exchange
| Description | Formats | |
|---|---|---|
AIP1 | Hyperledger Aries protocols from the AIP1 suite can be used to issue credentials and present proofs. This includes the protocols issue-credential-v1 and present-proof-v1 respectively. | |
AIP2 | Hyperledger Aries protocols from the AIP2 suite can also be used to issue credentials and present proofs. This includes the protocols issue-credential-v2 and present-proof-v2 respectively. |
Supported DID Methods
The cloud agent is able to resolve any DID, by use of a universal resolver.
Other Protocols
Some other notable protocols supported by the cloud agent include (but are not limited to):
| Description | |
|---|---|
AIP1 Connection Protocol | The cloud agent establishes DIDComm connections using the AIP1 connection protocol (RFC 0160). |
Aries Basic Messages | The cloud agent uses the AIP2 basic message protocol for exchanging arbitrary messages along a DIDComm connection (RFC 0095). |
Aries BBS+ Derived W3C VCs | The cloud agent supports the issuance of W3C credentials using BBS+ signatures (RFC 0646). This signature allows the holder to selectively disclose a subset of their W3C credential attributes when performing a proof exchange. |
