Constructor Summary

SecretKeySpec(byte[] key, int offset, int len, String algorithm)

SecretKeySpec(byte[] key, String algorithm)

Method Summary

boolean	equals(Object obj) Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison.
String	getAlgorithm() Returns the name of the algorithm that this key will work with.
byte[]	getEncoded() Returns the encoded form of the receiver.
String	getFormat() Returns the name of the format used to encode the key, or null if it can not be encoded.
int	hashCode() Returns an integer hash code for the receiver.

Method Detail

getAlgorithm

public String getAlgorithm()

Description copied from interface: Key

Returns the name of the algorithm that this key will work with. If the algorithm is unknown, it returns null.

Specified by:

getAlgorithm in interface Key

Returns:

String the receiver's algorithm

getFormat

public String getFormat()

Description copied from interface: Key

Returns the name of the format used to encode the key, or null if it can not be encoded.

Specified by:

getFormat in interface Key

Returns:

String the receiver's encoding format

getEncoded

public byte[] getEncoded()

Description copied from interface: Key

Returns the encoded form of the receiver.

Specified by:

getEncoded in interface Key

Returns:

byte[] the encoded form of the receiver

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.

Overrides:

hashCode in class Object

Returns:

int the receiver's hash.

See Also:

Object.equals(java.lang.Object)

equals

public boolean equals(Object obj)

Description copied from class: Object

Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. The implementation in Object returns true only if the argument is the exact same object as the receiver (==).

Overrides:

equals in class Object

Parameters:

obj - Object the object to compare with this object.

Returns:

boolean true if the object is the same as this object false if it is different from this object.

Object.hashCode()
