Class Summary

Modifier and Type	Class and Description
public class	AEADBadTagException This exception is thrown when a `Cipher` operating in an AEAD mode (such as GCM/CCM) is unable to verify the supplied authentication tag.
public class	BadPaddingException This exception is thrown when a particular padding mechanism is expected for the input data but the data is not padded properly.
public class	Cipher This class provides the functionality of a cryptographic cipher for encryption and decryption.
public class	CipherInputStream A `CipherInputStream` is composed of an `InputStream` and a `Cipher` object so that read() methods return data that are read in from the underlying `InputStream` but have been additionally processed by the `Cipher` object.
public class	CipherOutputStream A `CipherOutputStream` is composed of an `OutputStream` and a `Cipher` object so that write() methods first process the data before writing them out to the underlying `OutputStream`.
public abstract class	CipherSpi This class defines the Service Provider Interface (SPI) for the `Cipher` class.
pack-priv class	CryptoAllPermission The CryptoAllPermission is a permission that implies any other crypto permissions.
pack-priv class	CryptoAllPermissionCollection A `CryptoAllPermissionCollection` stores a collection of `CryptoAllPermission` objects.
public class	CryptoException Preview Third Preview of PEM Encodings of Cryptographic Objects (JEP 538). Thrown to indicate a cryptographic failure during processing.
pack-priv class	CryptoPermission The `CryptoPermission` class extends the `java.security.Permission` class.
pack-priv class	CryptoPermissionCollection A `CryptoPermissionCollection` object stores a set of `CryptoPermission` objects.
pack-priv class	CryptoPermissions This class contains `CryptoPermission` objects, organized into `PermissionCollection` objects according to algorithm names.
pack-priv class	CryptoPolicyParser JCE has two pairs of jurisdiction policy files: one represents U.S.
public class	DecapsulateException An exception that is thrown by the `javax.crypto.KEM.Decapsulator#decapsulate` method to denote an error during decapsulation.
public class	EncryptedPrivateKeyInfo This class implements the `EncryptedPrivateKeyInfo` type as defined in PKCS #8.
public class	ExemptionMechanism This class provides the functionality of an exemption mechanism, examples of which are key recovery, key weakening, and key escrow.
public class	ExemptionMechanismException This is the generic ExemptionMechanism exception.
public abstract class	ExemptionMechanismSpi This class defines the Service Provider Interface (SPI) for the `ExemptionMechanism` class.
pack-priv class	extObjectInputStream
public class	IllegalBlockSizeException This exception is thrown when the length of data provided to a block cipher is incorrect, i.e., does not match the block size of the cipher.
pack-priv class	JceSecurity This class instantiates implementations of JCE engine classes from providers registered with the java.security.Security object.
pack-priv class	JceSecurityManager The JCE security manager.
public class	KDF This class provides the functionality of a Key Derivation Function (KDF), which is a cryptographic algorithm for deriving additional keys from input keying material (IKM) and (optionally) other data.
public abstract class	KDFSpi This class defines the Service Provider Interface (SPI) for the Key Derivation Function (`KDF`) class.
public class	KEM This class provides the functionality of a Key Encapsulation Mechanism (KEM).
public class	KeyAgreement This class provides the functionality of a key agreement (or key exchange) protocol.
public abstract class	KeyAgreementSpi This class defines the Service Provider Interface (SPI) for the `KeyAgreement` class.
public class	KeyGenerator This class provides the functionality of a secret (symmetric) key generator.
public abstract class	KeyGeneratorSpi This class defines the Service Provider Interface (SPI) for the `KeyGenerator` class.
public class	Mac This class provides the functionality of a "Message Authentication Code" (MAC) algorithm.
public abstract class	MacSpi This class defines the Service Provider Interface (SPI) for the `Mac` class.
public class	NoSuchPaddingException This exception is thrown when a particular padding mechanism is requested but is not available in the environment.
public class	NullCipher The `NullCipher` class is a class that provides an "identity cipher" -- one that does not transform the plain text.
pack-priv class	NullCipherSpi This class provides a delegate for the identity cipher - one that does not transform the plain text.
pack-priv class	PermissionsEnumerator
pack-priv class	ProviderVerifier This class verifies Provider/Policy resources found at a URL (currently only JAR files and any supporting JAR files), and determines whether they may be used in this implementation.
public class	SealedObject This class enables a programmer to create an object and protect its confidentiality with a cryptographic algorithm.
public class	SecretKeyFactory This class represents a factory for secret keys.
public abstract class	SecretKeyFactorySpi This class defines the Service Provider Interface (SPI) for the `SecretKeyFactory` class.
public class	ShortBufferException This exception is thrown when an output buffer provided by the user is too short to hold the operation result.
