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 Cipher class. |
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 ExemptionMechanism class. |
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. |
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 SecretKeyFactory class. |
Exceptions
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. |
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.e., does not match the block size of the cipher. |
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. |
