Creates a new public key registration for Message Level Encryption. You can register your key using either direct registration (providing the JWK directly) or well-known endpoint registration (providing a URL where Method can fetch your JWKS).
Each key ID (kid) can only be registered once. Choose either direct or well-known registration for each unique key.

​
Body

​
type
string
required
The type of key registration. One of direct or well_known
​
contact
string
required
Contact email for the key registration.
​
jwk
object | null
The JSON Web Key object. Required for direct registration, null for well-known.
​
well_known_endpoint
string | null
URL to your JWKS endpoint. Required for well-known registration, null for direct.

​
Well-Known Endpoint Requirements

If using type: "well_known", your endpoint must return a JWKS that meets these requirements:
  1. Must have a top-level field named keys that has a list as its value.
  2. For a JWK (an item in list of keys) to be valid the following must be met:
    1. JWK must be an object
    2. JWK must have a field named kty and it must be equal to RSA
    3. JWK must have a field n and it must be a string that is valid n for a JWK in accordance to the RFC
    4. JWK must have a field e and it must be a string that is valid e for a JWK in accordance to the RFC
    5. JWK can optionally have a field named alg but if it is provided the value must be RSA-OAEP-256
    6. JWK must have a field kid and it must be a string that is a valid id which will be passed as cid when making requests to Method

​
Returns

Returns the created public key registration object with an assigned ID and active status.
