| * Represents a security configuration to be used for servers. There is no generic mechanism for |
| * processing arbitrary {@code ServerCredentials}; the consumer of the credential (the server) |
| * must support each implementation explicitly and separately. Consumers are not required to support |
| * all types or even all possible configurations for types that are partially supported, but they |
| * <em>must</em> at least fully support {@link ChoiceServerCredentials}. |
| * |
| * <p>A {@code ServerCredential} provides server identity. They can also influence types of |
| * encryption used and similar security configuration. |
| * |
| * <p>The concrete credential type should not be relevant to most users of the API and may be an |
| * implementation decision. Users should generally use the {@code ServerCredentials} type for |
| * variables instead of the concrete type. Freshly-constructed credentials should be returned as |
| * {@code ServerCredentials} instead of a concrete type to encourage this pattern. Concrete types |
| * would only be used after {@code instanceof} checks (which must consider |
| * {@code ChoiceServerCredentials}!). |
