All Implemented Interfaces:: KeySpec

Direct Known Subclasses:: PKCS8EncodedKeySpec, X509EncodedKeySpec

public abstract class EncodedKeySpecextends Object implements KeySpec

This class represents a public or private key in encoded format.

Since:

1.2

constructor:EncodedKeySpec(byte[]) [NONE]

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.

constructor:EncodedKeySpec(byte[],java.lang.String) [NONE]

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 ""
Since:: 9

method:getAlgorithm() [NONE]

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

method:getEncoded() [NONE]

getEncoded

public byte[] getEncoded()

Returns the encoded key.

Returns:: the encoded key. Returns a new array each time this method is called.

method:getFormat() [NONE]

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.
