KeyException

public class KeyException
extends GeneralSecurityException

java.lang.Object
↳	java.lang.Throwable
	↳	java.lang.Exception
		↳	java.security.GeneralSecurityException
			↳	java.security.KeyException

Known direct subclasses

InvalidKeyException, KeyManagementException

InvalidKeyException	This is the exception for invalid Keys (invalid encoding, wrong length, uninitialized, etc).
KeyManagementException	This is the general key management exception for all operations dealing with key management.

Known indirect subclasses

KeyExpiredException, KeyNotYetValidException, KeyPermanentlyInvalidatedException, UserNotAuthenticatedException, UserPresenceUnavailableException

KeyExpiredException	Indicates that a cryptographic operation failed because the employed key's validity end date is in the past.
KeyNotYetValidException	Indicates that a cryptographic operation failed because the employed key's validity start date is in the future.
KeyPermanentlyInvalidatedException	Indicates that the key can no longer be used because it has been permanently invalidated.
UserNotAuthenticatedException	Indicates that a cryptographic operation could not be performed because the user has not been authenticated recently enough.
UserPresenceUnavailableException	Indicates the condition that a proof of user-presence was requested but this proof was not presented.

This is the basic key exception.

Summary

Public constructors
`KeyException()` Constructs a KeyException with no detail message.
`KeyException(String msg)` Constructs a KeyException with the specified detail message.
`KeyException(String message, Throwable cause)` Creates a `KeyException` with the specified detail message and cause.
`KeyException(Throwable cause)` Creates a `KeyException` with the specified cause and a detail message of `(cause==null ? null : cause.toString())` (which typically contains the class and detail message of `cause`).

Inherited methods

From class


        
          java.lang.Throwable

`final void`	`addSuppressed(Throwable exception)` Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
`Throwable`	`fillInStackTrace()` Fills in the execution stack trace.
`Throwable`	`getCause()` Returns the cause of this throwable or `null` if the cause is nonexistent or unknown.
`String`	`getLocalizedMessage()` Creates a localized description of this throwable.
`String`	`getMessage()` Returns the detail message string of this throwable.
`StackTraceElement[]`	`getStackTrace()` Provides programmatic access to the stack trace information printed by `printStackTrace()`.
`final Throwable[]`	`getSuppressed()` Returns an array containing all of the exceptions that were suppressed, typically by the `try`-with-resources statement, in order to deliver this exception.
`Throwable`	`initCause(Throwable cause)` Initializes the cause of this throwable to the specified value.
`void`	`printStackTrace()` Prints this throwable and its backtrace to the standard error stream.
`void`	`printStackTrace(PrintWriter s)` Prints this throwable and its backtrace to the specified print writer.
`void`	`printStackTrace(PrintStream s)` Prints this throwable and its backtrace to the specified print stream.
`void`	`setStackTrace(StackTraceElement[] stackTrace)` Sets the stack trace elements that will be returned by `getStackTrace()` and printed by `printStackTrace()` and related methods.
`String`	`toString()` Returns a short description of this throwable.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

KeyException

public KeyException ()

Constructs a KeyException with no detail message. A detail message is a String that describes this particular exception.

KeyException

public KeyException (String msg)

Constructs a KeyException with the specified detail message. A detail message is a String that describes this particular exception.

Parameters
`msg`	`String`: the detail message.

KeyException

public KeyException (String message, 
                Throwable cause)

Creates a KeyException with the specified detail message and cause.

Parameters
`message`	`String`: the detail message (which is saved for later retrieval by the `Throwable.getMessage()` method).
`cause`	`Throwable`: the cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)

KeyException

public KeyException (Throwable cause)

Creates a KeyException with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause).

Parameters
`cause`	`Throwable`: the cause (which is saved for later retrieval by the `Throwable.getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)
