getRequiredParams

public LinkedHashMap<String,?> getRequiredParams()

Description copied from class: JWK

Returns the required JWK parameters. Intended as input for JWK thumbprint computation. See RFC 7638 for more information.

Specified by:

getRequiredParams in class JWK

Returns:

The required JWK parameters, sorted alphanumerically by key name and ready for JSON serialisation.

isPrivate

public boolean isPrivate()

Description copied from class: JWK

Returns true if this JWK contains private or sensitive (non-public) parameters.

toPublicJWK in class JWK

Returns:

The copied public RSA JWK.

toJSONObject

public net.minidev.json.JSONObject toJSONObject()

Description copied from class: JWK
