  +--acg.blocks.NonceAO

public class NonceAO

extends java.lang.Object

implements ACGObject

The NonceAO represents a nonce, which in this case is currently a random string of 128 bits.

Constructor Summary

NonceAO()
Constructs an empty nonce.

NonceAO(java.security.SecureRandom generator)
Constructs a nonce.

Method Summary

boolean	equals(NonceAO otherNonce)
byte[]	getNonceValue()
byte	getTypeID()
int	inputBytes(byte[] serialize, int start) Deserializes the NonceAO object.
static void	main(java.lang.String[] args)
byte[]	outputBytes() Serializes the NonceAO object.
boolean	selfTest()
void	setAny(boolean any) Do nothing method, for interface compatibility.

Constructor Detail

NonceAO

public NonceAO()

Constructs an empty nonce. I'm not really sure why this is still here.

NonceAO

public NonceAO(java.security.SecureRandom generator)

Constructs a nonce.

Parameters:

generator - a SecureRandom object used to generate the nonce.

Method Detail

setAny

public void setAny(boolean any)

Do nothing method, for interface compatibility.

Specified by:

setAny in interface ACGObject

Tags copied from interface: ACGObject

Parameters:

any - True if the ACGObject should just return its data byte array.

EncryptedAO

equals

public boolean equals(NonceAO otherNonce)

Parameters:

otherNonce - the nonce to be compared.

Returns:

true if this nonce is equal to otherNonce.

getNonceValue

public byte[] getNonceValue()

getTypeID

public byte getTypeID()

Specified by:

getTypeID in interface ACGObject

Returns:

a byte indicating this is of type nonce.

outputBytes

public byte[] outputBytes()
                   throws ACGException

Serializes the NonceAO object. 1 Type ID byte, 1 length byte, and 4 bytes of data.
Pos 0: TYPE_NONCE // type
Pos 1: nonceBytes //for now
Pos 2-5: XXXX XXXX XXXX XXXX// nonceBytes bytes for uniqueness

Specified by:

outputBytes in interface ACGObject

Returns:

a byte array with the serialized NonceAO object.

See Also:

inputBytes(byte[], int)

inputBytes

public int inputBytes(byte[] serialize,
                      int start)
               throws ACGException

Deserializes the NonceAO object.

Specified by:

inputBytes in interface ACGObject

Parameters:

serialize - the byte array from which to read the NonceAO

start - the index at which to start reading

Returns:

the number of bytes taken up by the serialized NonceAO object.
