Public Key
Represents an encoding of a public key, one half of a cryptographic key pair.
Serialization
PublicKey object serialization MUST conform to the following Avro schema:
{
"namespace": "org.dsnp",
"name": "PublicKey",
"type": "record",
"fields": [
{
"name": "publicKey",
"type": "bytes",
"doc": "Multicodec public key"
}
]
}
Generation
publicKey
- MUST be a public key of an allowed key type for the associated User Data type, encoded in
multicodec
format
The byte encoding consists of a multicodec key identifier (as a varint) followed by the public key's binary data in the codec's described format.
Allowed Key Types
User Data Type | Allowed Algorithms (multicodec) | Purpose |
---|---|---|
keyAgreementPublicKeys | x25519-pub | A Curve25519 public key that can be used in key exchange protocols to generate a shared secret |
assertionMethodPublicKeys | ed25519-pub | A public key for the EdDSA signature scheme using SHA-512 and Curve25519 that can be used to verify cryptographic signatures |
