  • Classes in javax.crypto used by javax.crypto 
    Class Description
    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.
