Interface | Description |
---|---|
SecretKey |
A secret key for symmetric cryptography.
|
Class | Description |
---|---|
Cipher |
This class implements a cryptographic cipher for transforming
data.
|
CipherInputStream |
This is an
InputStream that filters its data
through a Cipher before returning it. |
CipherOutputStream |
A filtered output stream that transforms data written to it with a
Cipher before sending it to the underlying output stream. |
CipherSpi |
This class represents the Service Provider Interface
(SPI) for cryptographic ciphers.
|
EncryptedPrivateKeyInfo |
An implementation of the
EncryptedPrivateKeyInfo ASN.1
type as specified in PKCS #8 -
Private-Key Information Syntax Standard. |
ExemptionMechanism |
An exemption mechanism, which will conditionally allow cryptography
where it is not normally allowed, implements things such as key
recovery, key weakening, or key escrow.
|
ExemptionMechanismSpi |
The Service Provider Interface (SPI) for the
ExemptionMechanism class. |
KeyAgreement |
Key agreement is a method in which two or more parties may agree on a
secret key for symmetric cryptography or message authentication
without transmitting any secrets in the clear.
|
KeyAgreementSpi |
This is the Service Provider Interface (SPI) for the
KeyAgreement class. |
KeyGenerator |
A generic producer of keys for symmetric cryptography.
|
KeyGeneratorSpi |
The Service Provider Interface (SPI) for the
KeyGenerator class. |
Mac |
This class implements a "message authentication code" (MAC), a method
to ensure the integrity of data transmitted between two parties who
share a common secret key.
|
MacSpi |
This is the Service Provider Interface (SPI) for the
Mac class. |
NullCipher |
Trivial subclass of Cipher that implements the identity
transformation, where the input is always copied to the output
unchanged.
|
SealedObject |
This class allows any
Serializable object to be
stored in an encrypted form. |
SecretKeyFactory | |
SecretKeyFactorySpi |
The Service Provider Interface (SPI) for the
SecretKeyFactory class. |
Exception | Description |
---|---|
BadPaddingException |
This exception is thrown during decryption when the decrypted input
does not have the proper padding bytes that are expected by the padding
mechanism.
|
ExemptionMechanismException |
Signals a general exception in an
ExemptionMechanism . |
IllegalBlockSizeException |
This exception is thrown when finishing encryption without padding or
decryption and the input is not a multiple of the cipher's block
size.
|
NoSuchPaddingException |
This exception is thrown when a particular padding scheme is
requested but is not available.
|
ShortBufferException |
This exception is thrown on an attempt to transform bytes into a
buffer that is too short to contain the data.
