prime_
protected ByteArrayAttribute prime_
- The prime (p) of this DH key.
base_
protected ByteArrayAttribute base_
- The base (g) of this DH key.
value_
protected ByteArrayAttribute value_
- The public value (y) of this DH key.
DHPublicKey
public DHPublicKey()
- Deafult Constructor.
DHPublicKey
protected DHPublicKey(Session session,
long objectHandle)
throws TokenException
- Called by getInstance to create an instance of a PKCS#11 DH public key.
- Parameters:
session
- The session to use for reading attributes.
This session must have the appropriate rights; i.e.
it must be a user-session, if it is a private object.objectHandle
- The object handle as given from the PKCS#111 module.- Throws:
TokenException
- If getting the attributes failed.
getInstance
public static Object getInstance(Session session,
long objectHandle)
throws TokenException
- The getInstance method of the PublicKey class uses this method to create
an instance of a PKCS#11 DH public key.
- Parameters:
session
- The session to use for reading attributes.
This session must have the appropriate rights; i.e.
it must be a user-session, if it is a private object.objectHandle
- The object handle as given from the PKCS#111 module.- Returns:
- The object representing the PKCS#11 object.
The returned object can be casted to the
according sub-class.
- Throws:
TokenException
- If getting the attributes failed.
putAttributesInTable
protected static void putAttributesInTable(DHPublicKey object)
- Put all attributes of the given object into the attributes table of this
object. This method is only static to be able to access invoke the
implementation of this method for each class separately (see use in
clone()).
- Parameters:
object
- The object to handle.
allocateAttributes
protected void allocateAttributes()
- Allocates the attribute objects for this class and adds them to the
attribute table.
- Overrides:
allocateAttributes
in class PublicKey
clone
public java.lang.Object clone()
- Create a (deep) clone of this object.
- Overrides:
clone
in class PublicKey
- Returns:
- A clone of this object.
equals
public boolean equals(java.lang.Object otherObject)
- Compares all member variables of this object with the other object.
Returns only true, if all are equal in both objects.
- Overrides:
equals
in class PublicKey
- Parameters:
otherObject
- The other object to compare to.- Returns:
- True, if other is an instance of this class and all member
variables of both objects are equal. False, otherwise.
getPrime
public ByteArrayAttribute getPrime()
- Gets the prime attribute of this DH key.
- Returns:
- The prime attribute.
getBase
public ByteArrayAttribute getBase()
- Gets the base attribute of this DH key.
- Returns:
- The base attribute.
getValue
public ByteArrayAttribute getValue()
- Gets the value attribute of this DH key.
- Returns:
- The value attribute.
readAttributes
public void readAttributes(Session session)
throws TokenException
- Read the values of the attributes of this object from the token.
- Overrides:
readAttributes
in class PublicKey
- Parameters:
session
- The session handle to use for reading attributes.
This session must have the appropriate rights; i.e.
it must be a user-session, if it is a private object.- Throws:
TokenException
- If getting the attributes failed.
toString
public java.lang.String toString()
- This method returns a string representation of the current object. The
output is only for debugging purposes and should not be used for other
purposes.
- Overrides:
toString
in class PublicKey
- Returns:
- A string presentation of this object for debugging output.
