Method Detail

getAlgorithm

public java.lang.String getAlgorithm()

Description copied from interface: Key

Returns the algorithm for which this key is primarily used.

Specified by:

getAlgorithm in interface java.security.Key

getBitLength

public int getBitLength()

Description copied from interface: Key

Returns the number of bits required to represent this key's defining key material. For example, in the case of an RSA key, the bit length of the modulus would be returned.

getKey

public java.security.interfaces.ECKey getKey()

getParams

public java.security.spec.ECParameterSpec getParams()

Specified by:

getParams in interface java.security.interfaces.ECKey

getAlgID

public AlgorithmIdentifier getAlgID()

getContents

public ASN1Object getContents()

clone

public abstract java.lang.Object clone()

Description copied from interface: Key

Performs a deep clone of the Key instance.

Overrides:

clone in class java.lang.Object

Returns:

A deep clone of the Key instance.

erase

public void erase()

Description copied from interface: Key

Erases the sensitive key material of a private or symmetric key, making the key un-usable. Keys may be erased multiple times with no consequences.

Note: After erase() has been invoked, no other methods of the Key object are guaranteed to function correctly. In particular, invoking another method after erase() may result in a NullPointerException being thrown.

writeExternal

public void writeExternal(java.io.ObjectOutput os)
                   throws java.io.IOException

Specified by:

writeExternal in interface java.io.Externalizable

Throws:

java.io.IOException

readExternal

public void readExternal(java.io.ObjectInput is)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Specified by:

readExternal in interface java.io.Externalizable

Throws:

java.io.IOException

java.lang.ClassNotFoundException
