@Alpha
public final class EcdsaParameters
extends SignatureParameters

Describes the parameters of an ECDSA signature primitive.

This API is annotated with Alpha because it is not yet stable and might be changed in the future.

Overrides:

hasIdRequirement

public boolean hasIdRequirement()

Description copied from class: Parameters

Returns true if a key created with the parameters in this object has to have a certain ID when it is in a keyset.

In Tink, certain keys change their behavior depending on the key id (for example, an Aead object can prefix the ciphertext with the big endian encoding of the key id). If this is the case, such a key should require a unique id in Key.getIdRequirementOrNull() and return true here.
