| 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)
Returns a Cipher object that implements the specified
 transformation. | 
static Cipher | 
Cipher.getInstance(String transformation,
            Provider provider)
Returns a Cipher object that implements the specified
 transformation. | 
static Cipher | 
Cipher.getInstance(String transformation,
            String provider)
Returns a Cipher object that implements the specified
 transformation. | 
| Methods in javax.crypto with parameters of type Cipher | |
|---|---|
 PKCS8EncodedKeySpec | 
EncryptedPrivateKeyInfo.getKeySpec(Cipher cipher)
Extract the enclosed PKCS8EncodedKeySpec object from the encrypted data and return it.  | 
 Object | 
SealedObject.getObject(Cipher c)
Retrieves the original (encapsulated) object.  | 
| Constructors in javax.crypto with parameters of type Cipher | |
|---|---|
CipherInputStream(InputStream is,
                  Cipher c)
Constructs a CipherInputStream from an InputStream and a Cipher.  | 
|
CipherOutputStream(OutputStream os,
                   Cipher c)
Constructs a CipherOutputStream from an OutputStream and a Cipher.  | 
|
SealedObject(Serializable object,
             Cipher c)
Constructs a SealedObject from any Serializable object.  |
