| 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 | NullCipherThe 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 Cipherobject that implements the specified
 transformation. | 
| static Cipher | Cipher.getInstance(String transformation,
            Provider provider)Returns a Cipherobject that implements the specified
 transformation. | 
| static Cipher | Cipher.getInstance(String transformation,
            String provider)Returns a Cipherobject 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. | |
