/**
 * Base class for exceptions during cryptographic operations which cannot throw a suitable checked
 * exception.
 *
 * <p>The contract of the majority of crypto primitives/operations (e.g. {@code Cipher} or
 * {@code Signature}) is that they can throw a checked exception during initialization, but are not
 * permitted to throw a checked exception during operation. Because crypto operations can fail
 * for a variety of reasons after initialization, this base class provides type-safety for unchecked
 * exceptions that may be thrown in those cases.
