Uses of Package
javax.crypto

Packages that use javax.crypto
java.security Provides the classes and interfaces for the security framework. 
javax.crypto Provides the classes and interfaces for cryptographic operations. 
javax.crypto.interfaces Provides interfaces for Diffie-Hellman keys as defined in RSA Laboratories' PKCS #3. 
javax.crypto.spec Provides classes and interfaces for key specifications and algorithm parameter specifications. 
javax.security.auth.kerberos This package contains utility classes related to the Kerberos network authentication protocol. 
 

Classes in javax.crypto used by java.security
SecretKey
          A secret (symmetric) key.
 

Classes in javax.crypto used by javax.crypto
BadPaddingException
          This exception is thrown when a particular padding mechanism is expected for the input data but the data is not padded properly.
Cipher
          This class provides the functionality of a cryptographic cipher for encryption and decryption.
CipherSpi
          This class defines the Service Provider Interface (SPI) for the Cipher class.
ExemptionMechanism
          This class provides the functionality of an exemption mechanism, examples of which are key recovery, key weakening, and key escrow.
ExemptionMechanismException
          This is the generic ExemptionMechanism exception.
ExemptionMechanismSpi
          This class defines the Service Provider Interface (SPI) for the ExemptionMechanism 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.
KeyAgreement
          This class provides the functionality of a key agreement (or key exchange) protocol.
KeyAgreementSpi
          This class defines the Service Provider Interface (SPI) for the KeyAgreement class.
KeyGenerator
          This class provides the functionality of a secret (symmetric) key generator.
KeyGeneratorSpi
          This class defines the Service Provider Interface (SPI) for the KeyGenerator class.
Mac
          This class provides the functionality of a "Message Authentication Code" (MAC) algorithm.
MacSpi
          This class defines the Service Provider Interface (SPI) for the Mac class.
NoSuchPaddingException
          This exception is thrown when a particular padding mechanism is requested but is not available in the environment.
SealedObject
          This class enables a programmer to create an object and protect its confidentiality with a cryptographic algorithm.
SecretKey
          A secret (symmetric) key.
SecretKeyFactory
          This class represents a factory for secret keys.
SecretKeyFactorySpi
          This class defines the Service Provider Interface (SPI) for the SecretKeyFactory class.
ShortBufferException
          This exception is thrown when an output buffer provided by the user is too short to hold the operation result.
