Represents a cryptographic function without the actual key material.
In Tink, a Key represents a set of cryptographic functions. The Parameters class contains all the information about the function which is not randomly chosen with each instance.

  - hasIdRequirement
```
public abstract boolean hasIdRequirement()
```
    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.
