public AsconXof(AsconXof.AsconParameters parameters)

Deprecated.

Method Detail

update

public void update(byte in)

Deprecated.

Description copied from interface: Digest

update the message digest with a single byte.

Specified by:

update in interface Digest

Parameters:

in - the input byte to be entered.

update

public void update(byte[] input,
                   int inOff,
                   int len)

Deprecated.

Description copied from interface: Digest

update the message digest with a block of bytes.

Specified by:

update in interface Digest

Parameters:

input - the byte array containing the data.

inOff - the offset into the byte array where the data starts.

len - the length of the data.

padAndAbsorb

protected void padAndAbsorb()

Deprecated.

pad

protected long pad(int i)

Deprecated.

loadBytes

protected long loadBytes(byte[] bytes,
                         int inOff)

Deprecated.

loadBytes

protected long loadBytes(byte[] bytes,
                         int inOff,
                         int n)

Deprecated.

setBytes

protected void setBytes(long w,
                        byte[] bytes,
                        int inOff)

Deprecated.

setBytes

protected void setBytes(long w,
                        byte[] bytes,
                        int inOff,
                        int n)

Deprecated.

getAlgorithmName

public java.lang.String getAlgorithmName()

Deprecated.

Description copied from interface: Digest

return the algorithm name

Specified by:

getAlgorithmName in interface Digest

Returns:

the algorithm name

doOutput

public int doOutput(byte[] output,
                    int outOff,
                    int outLen)

Deprecated.

Description copied from interface: Xof

Start outputting the results of the final calculation for this digest. Unlike doFinal, this method will continue producing output until the Xof is explicitly reset, or signals otherwise.

Specified by:

doOutput in interface Xof

Parameters:

output - output array to write the output bytes to.

outOff - offset to start writing the bytes at.

outLen - the number of output bytes requested.

Returns:

the number of bytes written

doFinal

public int doFinal(byte[] output,
                   int outOff,
                   int outLen)

Deprecated.

Description copied from interface: Xof

Output the results of the final calculation for this digest to outLen number of bytes.

Specified by:

doFinal in interface Xof

Parameters:

output - output array to write the output bytes to.

outOff - offset to start writing the bytes at.

outLen - the number of output bytes requested.

Returns:

the number of bytes written

getByteLength

public int getByteLength()

Deprecated.

Description copied from interface: ExtendedDigest

Return the size in bytes of the internal buffer the digest applies it's compression function to.

Specified by:

getByteLength in interface ExtendedDigest

Returns:

byte length of the digests internal buffer.

reset

public void reset()

Deprecated.

Description copied from interface: Digest

reset the digest back to it's initial state.

Specified by:

reset in interface Digest

p

protected void p(int nr)

getDigestSize

public int getDigestSize()

Description copied from interface: Digest

return the size, in bytes, of the digest produced by this message digest.

Specified by:

getDigestSize in interface Digest

Returns:

the size, in bytes, of the digest produced by this message digest.

doFinal

public int doFinal(byte[] output,
                   int outOff)

close the digest, producing the final digest value. The doFinal call leaves the digest reset.

Specified by:

doFinal in interface Digest

Parameters:

output - the array the digest is to be copied into.

outOff - the offset into the out array the digest is to start at.
