public SafePbeParameters()
```
- Method Detail
  - clone
```
public P clone()
```
    Description copied from interface: SafeKey
    
    Returns a deep clone of this safe key.
    
    Specified by:
    
    clone in interface SafeKey<P extends SafePbeParameters<S,P>>
    
    Overrides:
    
    clone in class Object
  - getKeyStrength
```
@Nullable
public S getKeyStrength()
```
    Returns the cipher key strength.
    
    Returns:
    The cipher key strength.
  - getKeyStrengthValues
```
public abstract S[] getKeyStrengthValues()
```
    Returns a new non-empty array of all available key strength values. There should be no duplicated elements in this array.
    
    Returns:
    A new non-empty array of all available key strength values.
  - getPassword
```
@Nullable
public char[] getPassword()
```
    Returns a protective copy of the stored password char array.
    
    Returns:
    A protective copy of the stored password char array.
  - reset
```
public void reset()
```
    Description copied from interface: SafeKey
    
    Wipes any key data from the heap and resets this safe key to it's initial state.
    
    Specified by:
    
    reset in interface SafeKey<P extends SafePbeParameters<S,P>>
  - setKeyFileBytes
```
public void setKeyFileBytes(@CheckForNull
                   byte[] bytes)
```
    Decodes the given byte array to a password char array for subsequent use. This method should be used if a key file is used rather than a password.
    This method makes a protective copy of the given key file byte array. It's highly recommended to overwrite this array with any non-password data after calling this method.
    
    Parameters:
    bytes - the byte array to decode.
  - setKeyStrength
```
public void setKeyStrength(@CheckForNull
                  S keyStrength)
```
    Sets the cipher key strength.
    
    Parameters:
    keyStrength - the cipher key strength.
  - setPassword
```
public void setPassword(@CheckForNull
               char[] newPW)
```
    Copies and stores the given password char array for deriving the cipher key. It's highly recommended to overwrite this array with any non-password data after calling this method.
    
    Parameters:
    newPW - the password char array for deriving the cipher key.
