Salsa20Chacha20Poly1305MessageParameters

public Salsa20Chacha20Poly1305MessageParameters(byte[] pNonce,
                                                byte[] pTag)

Create a new Salsa20Chacha20Poly1305MessageParameters object with the given attributes.

Parameters:

pNonce - The nonce.

pTag - authentication tag which is returned on MessageEncrypt, and provided on MessageDecrypt.

Method Detail

clone

public java.lang.Object clone()

Create a (deep) clone of this object.

Overrides:

clone in class java.lang.Object

Returns:

A clone of this object.

Postconditions:

(result != null) and (result instanceof Salsa20Chacha20Poly1305MessageParameters) and (result.equals(this))

public java.lang.Object getPKCS11ParamsObject()

Get this parameters object as an object of the CK_SALSA20_CHACHA20_MSG_POLY1305_PARAMS class.

Specified by:

getPKCS11ParamsObject in interface Parameters

Returns:

This object as a CK_SALSA20_CHACHA20_POLY1305_MSG_PARAMS object.

Postconditions:

(result != null)

setValuesFromPKCS11Object

public void setValuesFromPKCS11Object(java.lang.Object obj)

Read the parameters from the PKCS11Object and overwrite the values into this object.

Specified by:

setValuesFromPKCS11Object in interface MessageParameters

Parameters:

obj - Object to read the parameters from

toString in class java.lang.Object

Returns:

A string representation 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 java.lang.Object

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.

hashCode

public int hashCode()

The overriding of this method should ensure that the objects of this class work correctly in a hashtable.
