- Constructor Detail
  - EncodedKeySpec
```
public EncodedKeySpec(byte[] encodedKey)
```
    Creates a new EncodedKeySpec with the given encoded key.
    
    Parameters:
    
    encodedKey - the encoded key. The contents of the array are copied to protect against subsequent modification.
    
    Throws:
    
    NullPointerException - if encodedKey is null.
  - EncodedKeySpec
```
protected EncodedKeySpec(byte[] encodedKey,
                         String algorithm)
```
    Creates a new EncodedKeySpec with the given encoded key. This constructor is useful when subsequent callers of the EncodedKeySpec object might not know the algorithm of the key.
    
    Parameters:
    
    encodedKey - the encoded key. The contents of the array are copied to protect against subsequent modification.
    
    algorithm - the algorithm name of the encoded key See the KeyFactory section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names.
    
    Throws:
    
    NullPointerException - if encodedKey or algorithm is null.
    
    IllegalArgumentException - if algorithm is the empty string ""

  - getAlgorithm
```
public String getAlgorithm()
```
    Returns the name of the algorithm of the encoded key.
    
    Returns:
    
    the name of the algorithm, or null if not specified
    
    Since:
    
    9
  - getEncoded
```
public byte[] getEncoded()
```
    Returns the encoded key.
    
    Returns:
    
    the encoded key. Returns a new array each time this method is called.
  - getFormat
```
public abstract String getFormat()
```
    Returns the name of the encoding format associated with this key specification.
    If the opaque representation of a key (see Key) can be transformed (see KeyFactory) into this key specification (or a subclass of it), getFormat called on the opaque key returns the same value as the getFormat method of this key specification.
    
    Returns:
    
    a string representation of the encoding format.
