Javax.Crypto Namespace

This package provides the classes and interfaces for cryptographic applications implementing algorithms for encryption, decryption, or key agreement.

Classes

AEADBadTagException

Thrown by a Cipher that is using an Authenticated Encryption with Additional Data (AEAD) mode such as Galois/Counter Mode (GCM) and the tag failed verification.

BadPaddingException

The exception that is thrown when a padding mechanism is expected for the input data, but the input data does not have the proper padding bytes.

Cipher

This class provides access to implementations of cryptographic ciphers for encryption and decryption.

CipherInputStream

This class wraps an InputStream and a cipher so that read() methods return data that are read from the underlying InputStream and processed by the cipher.

CipherOutputStream

This class wraps an output stream and a cipher so that write methods send the data through the cipher before writing them to the underlying output stream.

CipherSpi

This class defines the Service Provider Interface (SPI) for cryptographic ciphers.

EncryptedPrivateKeyInfo

This class implements the EncryptedPrivateKeyInfo ASN.1 type as specified in .

ExemptionMechanism

This class implements the functionality of an exemption mechanism such as key recovery, key weakening, or key escrow.

ExemptionMechanismException

This is the base class for ExemptionMechanismException.

ExemptionMechanismSpi

The Service Provider Interface (SPI) definition for the ExemptionMechanism class.

IllegalBlockSizeException

The exception, that is thrown when the data length provided to a block cipher does not match the block size of the cipher.

KeyAgreement

This class provides the functionality for a key exchange protocol.

KeyAgreementSpi

The Service Provider Interface (SPI) definition for the KeyAgreement class.

KeyGenerator

This class provides the public API for generating symmetric cryptographic keys.

KeyGeneratorSpi

The Service Provider Interface (SPI) definition for the KeyGenerator class.

Mac

Message Authentication Code

MacSpi

The Service-Provider Interface (SPI) definition for the Mac class.

NoSuchPaddingException

The exception that is thrown when the requested padding mechanism is not supported.

NullCipher

This class provides an identity cipher that does not transform the input data in any way.

SealedObject

A SealedObject is a wrapper around a serializable object instance and encrypts it using a cryptographic cipher.

SecretKey

A cryptographic secret (symmetric) key.

SecretKeyConsts
SecretKeyFactory

The public API for SecretKeyFactory implementations.

SecretKeyFactorySpi

The Service Provider Interface (SPI) definition for the SecretKeyFactory class.

ShortBufferException

The exception that is thrown when the result of an operation is attempted to store in a user provided buffer that is too small.

Interfaces

ISecretKey

A cryptographic secret (symmetric) key.

Enums

CipherMode

Enumerates values returned by several types and taken as a parameter of several methods of Cipher.

KeyType
