Interfaces
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. |
