Method Detail

getAlgorithm

public String getAlgorithm()

Description copied from interface: Key

Returns the name of the algorithm of this key. If the algorithm is unknown, null is returned.

Specified by:

getAlgorithm in interface Key

Returns:

the name of the algorithm of this key or null if the algorithm is unknown.

getFormat

public String getFormat()

Description copied from interface: Key

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

Specified by:

getFormat in interface Key

Returns:

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

getEncoded

public byte[] getEncoded()

Description copied from interface: Key

Returns the encoded form of this key, or null if encoding is not supported by this key.

Specified by:

getEncoded in interface Key

Returns:

the encoded form of this key, or null if encoding is not supported by this key.

getParams

public ECParameterSpec getParams()

Description copied from interface: ECKey

Returns the EC key parameters.

Returns:

the EC key parameters.

getParameters

public ECParameterSpec getParameters()

Description copied from interface: ECKey

return a parameter specification representing the EC domain parameters for the key.

Specified by:

getParameters in interface ECKey

getW

public ECPoint getW()

Description copied from interface: ECPublicKey

Returns the public point W on an elliptic curve (EC).

Returns:

the public point W on an elliptic curve (EC).

getQ

public ECPoint getQ()

Description copied from interface: ECPublicKey

return the public point Q

Specified by:

getQ in interface ECPublicKey

engineGetQ

public ECPoint engineGetQ()

toString

public String toString()

Description copied from class: Object

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Overrides:

toString in class Object

Returns:

a printable representation of this object.

setPointFormat

public void setPointFormat(String style)

Description copied from interface: ECPointEncoder

Set the formatting for encoding of points. If the String "UNCOMPRESSED" is passed in point compression will not be used. If the String "COMPRESSED" is passed point compression will be used. The default is "UNCOMPRESSED".

Specified by:

setPointFormat in interface ECPointEncoder

Parameters:

style - the style to use.

equals

public boolean equals(Object o)

Description copied from class: Object

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Overrides:

equals in class Object

Parameters:

o - the object to compare this instance with.

Returns:

true if the specified object is equal to this Object; false otherwise.

See Also:

Object.hashCode()

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Overrides:

hashCode in class Object

Returns:

this object's hash code.

Object.equals(java.lang.Object)
