ProtectionParameter.| Constructor and Description | 
|---|
| PasswordProtection(char[] password)Creates a password parameter. |

| boolean | isDestroyed()Determines if password has been cleared. | 
public PasswordProtection(char[] password)
 The specified password is cloned before it is stored
 in the new PasswordProtection object.

 For example, the
 keystore.PKCS12.keyProtectionAlgorithm property stores the
 name of the default key protection algorithm used for PKCS12
 keystores. If the security property is not set, an
 implementation-specific algorithm will be used.null if none was setpublic AlgorithmParameterSpec getProtectionParameters()

Note that this method returns a reference to the password. If a clone of the array is created it is the caller's responsibility to zero out the password information after it is no longer needed.
