## Uses of Class
javax.crypto.Cipher

Packages that use Cipher
javax.crypto | Provides the classes and interfaces for cryptographic operations.

Uses of Cipher in javax.crypto

Subclasses of Cipher in javax.crypto
`class` | `NullCipher` The NullCipher class is a class that provides an "identity cipher" -- one that does not tranform the plaintext.

Methods in javax.crypto that return Cipher
`static Cipher` | `Cipher.getInstance(String transformation)` Generates a `Cipher` object that implements the specified transformation.
`static Cipher` | `Cipher.getInstance(String transformation, String provider)` Creates a `Cipher` object that implements the specified transformation, as supplied by the specified provider.
`static Cipher` | `Cipher.getInstance(String transformation, Provider provider)` Creates a `Cipher` object that implements the specified transformation, as supplied by the specified provider.

Methods in javax.crypto with parameters of type Cipher
`Object` | `SealedObject.getObject(Cipher c)` Retrieves the original (encapsulated) object.
`PKCS8EncodedKeySpec` | `EncryptedPrivateKeyInfo.getKeySpec(Cipher c)` Extract the enclosed PKCS8EncodedKeySpec object from the encrypted data and return it.

Constructors in javax.crypto with parameters of type Cipher
`SealedObject(Serializable object, Cipher c)` Constructs a SealedObject from any Serializable object.
`CipherOutputStream(OutputStream os, Cipher c)` Constructs a CipherOutputStream from an OutputStream and a Cipher.
`CipherInputStream(InputStream is, Cipher c)` Constructs a CipherInputStream from an InputStream and a Cipher.
