Constructor Detail

Salsa20Chacha20Poly1305Parameters

public Salsa20Chacha20Poly1305Parameters(byte[] pNonce,
                                         byte[] pAAD)

Create a new Salsa20Chacha20Poly1305Parameters object with the given attributes.

Parameters:

pNonce - nonce (This should be never re-used with the same key.)
length of nonce in bits (is 64 for original, 96 for IETF (only for chacha20) and 192 for xchacha20/xsalsa20 variant)

pAAD - additional authentication data. This data is authenticated but not encrypted.

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 Salsa20Chacha20Poly1305Parameters) and (result.equals(this))

getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()

Get this parameters object as an object of the CK_SALSA20_CHACHA20_POLY1305_PARAMS class.

Returns:

This object as a CK_SALSA20_CHACHA20_POLY1305_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.

Parameters:

obj - Object to read the parameters from

toString

public java.lang.String toString()

Returns the string representation of this object. Do not parse data from this string, it is for debugging only.

Overrides:

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.

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code of this object.
