DIDComm Message Envelope

See: https://identity.foundation/didcomm-messaging/spec/v2.1/#iana-media-types

Variants§

§

PlainJson

Unsiged JSON encoded message.

Envelope: plaintext (no envelope) Media Type: application/didcomm-plain+json

Fields

§header: DidCommHeader
§body: String
§

SignedJson

Signed JSON encoded message.

The identity has been verified when this is constructed.

Envelope: signed(plaintext) Media Type: application/didcomm-signed+json

Fields

§sender: Did
§header: DidCommHeader
§body: String
§

AnonCryptJson

Encrypted JSON encoded message.

Guarantees confidentiality and integrity without revealing the identity of the sender.

Envelope: anoncrypt(plaintext) Media Type: application/didcomm-encrypted+json

Fields

§header: DidCommHeader
§body: String
§

AuthCryptJson

Encrypted authenticated JSON encoded message.

Guarantees confidentiality and integrity. Also proves the identity of the sender – but in a way that only the recipient can verify. This is the default wrapping choice, and SHOULD be used unless a different goal is clearly identified. By design, this combination and all other combinations that use encryption in their outermost layer share an identical IANA media type, because only the recipient should care about the difference. Media Type: application/didcomm-encrypted+json

The identity has been verified when this is constructed.

Envelope: authcrypt(plaintext) Media Type: application/didcomm-encrypted+json

Fields

§sender: Did
§header: DidCommHeader
§body: String
