Interfaces
SecretKey |
A secret (symmetric) key. |
Classes
Cipher |
This class provides the functionality of a cryptographic cipher for encryption and decryption. |
CipherInputStream |
A CipherInputStream is composed of an InputStream and a Cipher so that read() methods return data that are read in from the underlying InputStream but have been additionally processed by the Cipher. |
CipherOutputStream |
A CipherOutputStream is composed of an OutputStream and a Cipher so that write() methods first process the data before writing them out to the underlying OutputStream. |
CipherSpi |
This class defines the Service Provider Interface (SPI) for the |
EncryptedPrivateKeyInfo |
This class implements the |
ExemptionMechanism |
This class provides the functionality of an exemption mechanism, examples of which are key recovery, key weakening, and key escrow. |
ExemptionMechanismSpi |
This class defines the Service Provider Interface (SPI) for the |
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 |
KeyGenerator |
This class provides the functionality of a secret (symmetric) key generator. |
KeyGeneratorSpi |
This class defines the Service Provider Interface (SPI) for the |
Mac |
This class provides the functionality of a "Message Authentication Code" (MAC) algorithm. |
MacSpi |
This class defines the Service Provider Interface (SPI) for the |
NullCipher |
The NullCipher class is a class that provides an "identity cipher" -- one that does not transform the plain text. |
SealedObject |
This class enables a programmer to create an object and protect its confidentiality with a cryptographic algorithm. |
SecretKeyFactory |
This class represents a factory for secret keys. |
SecretKeyFactorySpi |
This class defines the Service Provider Interface (SPI) for the |
Exceptions
AEADBadTagException |
This exception is thrown when a |
BadPaddingException |
This exception is thrown when a particular padding mechanism is expected for the input data but the data is not padded properly. |
ExemptionMechanismException |
This is the generic ExemptionMechanism exception. |
IllegalBlockSizeException |
This exception is thrown when the length of data provided to a block cipher is incorrect, i. |
NoSuchPaddingException |
This exception is thrown when a particular padding mechanism is requested but is not available in the environment. |
ShortBufferException |
This exception is thrown when an output buffer provided by the user is too short to hold the operation result. |
