Public constructors
EncodedKeySpec
public EncodedKeySpec (byte[] encodedKey)
Creates a new EncodedKeySpec
with the given encoded key.
Parameters | |
---|---|
encodedKey |
byte : the encoded key. The contents of the
array are copied to protect against subsequent modification. |
Throws | |
---|---|
NullPointerException |
if encodedKey
is null. |
Protected constructors
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 |
byte : the encoded key. The contents of the
array are copied to protect against subsequent modification. |
algorithm |
String : 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 "" |
Public methods
getAlgorithm
public String getAlgorithm ()
Returns the name of the algorithm of the encoded key.
Returns | |
---|---|
String |
the name of the algorithm, or null if not specified |
getEncoded
public byte[] getEncoded ()
Returns the encoded key.
Returns | |
---|---|
byte[] |
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 | |
---|---|
String |
a string representation of the encoding format. |
