| Cipher | This class implements a cryptographic cipher for transforming
data.
Ciphers cannot be instantiated directly; rather one of the
getInstance must be used to instantiate a given
transformation, optionally with a specific provider.
A transformation is of the form:
- algorithm/mode/padding, or
- algorithm
where algorithm is the base name of a cryptographic cipher
(such as "AES"), mode is the abbreviated name of a block
cipher mode (such as "CBC" for cipher block chaining mode), and
padding is the name of a padding scheme (such as
"PKCS5Padding"). |
| 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.
Providers of cryptographic ciphers must subclass this for every
cipher they implement, implementing the abstract methods as
appropriate, then provide an entry that points to the subclass in
their implementation of Provider.
CipherSpi objects are instantiated along with Ciphers when
the Cipher.getInstance(String) methods are invoked.
|
| 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 | A secret key factory translates SecretKey objects to and from
KeySpec objects, and can translate between
different vendors' representations of SecretKey objects (for
security or semantics; whichever applies).
|
| SecretKeyFactorySpi | The Service Provider Interface (SPI) for the SecretKeyFactory class.
