Class SymmetricEncryptionFilter

java.lang.Object
com.tangosol.util.Base
com.tangosol.net.security.AbstractEncryptionFilter
com.tangosol.net.security.SymmetricEncryptionFilter

All Implemented Interfaces:

WrapperStreamFactory, XmlConfigurable

Direct Known Subclasses:

PasswordBasedEncryptionFilter

Deprecated. As of Coherence 3.7, deprecated replaced by SSL.

@Deprecated
public class SymmetricEncryptionFilter

extends AbstractEncryptionFilter

Symmetric encryption filter implementation.

This filter encrypts data using a shared symmetric encryption key. It may either be configured with a pre-distributed shared key, or with a randomly generated key via the ClusterEncryptionFilter.

Deprecated.

The SecretKey

DEFAULT_KEYSTORE_TYPE

public static final java.lang.String DEFAULT_KEYSTORE_TYPE

Deprecated.

Default KeyStore type. JCEKS is used over JKS as it supports storage of symetric keys.

Method Detail

getInputStream

public java.io.InputStream getInputStream(java.io.InputStream stream)

Deprecated.

Description copied from interface: WrapperStreamFactory

Requests an InputStream that wraps the passed InputStream.

Parameters:

stream - the java.io.InputStream to be wrapped

Returns:

an InputStream that delegates to ("wraps") the passed InputStream

getOutputStream

public java.io.OutputStream getOutputStream(java.io.OutputStream stream)

Deprecated.

Description copied from interface: WrapperStreamFactory

Requests an OutputStream that wraps the passed OutputStream.

Parameters:

stream - the java.io.OutputStream to be wrapped

Returns:

an OutputStream that delegates to ("wraps") the passed OutputStream

setConfig

public void setConfig(XmlElement xml)

Deprecated.

Configures the Encryption filter for symetric encryption using a key from a KeyStore. Supported configuration parameters include:

<li/> keyAlias - (required) the alias to use in reading the key from the keystore <li/> keyPassword - (required) the password to use in reading the key <li/> transformation - the cipher algorithm/mode/padding, defaults to key's algorithm and cipher provider defaults <li/> storeType - the type of KeyStore, defaults to JCEKS <li/> store - the URL of the KeyStore, defaults to .keystore <li/> storePassword - the password to use to access the store, defaults to keyPassword

Parameters:

xml - the XML configuration for the object

setKey

public void setKey(javax.crypto.SecretKey key)

Deprecated.

Specify the filter's encryption key.

Parameters:

key - the filter's encryption key

getKey

public javax.crypto.SecretKey getKey()

Deprecated.

Return the filter's encryption key.

Returns:

the filter's encryption key

generateKey

public static javax.crypto.SecretKey generateKey(java.lang.String sAlgorithm,
                                                 int nKeySize)

Deprecated.

Generate a secret key according the the supplied parameters.

Parameters:

sAlgorithm - the key algorithm

nKeySize - the key size

Returns:

the secret key

main

public static void main(java.lang.String[] asArgv)

Deprecated.

Generates and insert a symmetric key into a keystore.

This utility is provided as the keytool utility distributed with the JDK only supports asymmetric keys.

Parameters:

asArgv - command line parameters
