doFinalback to summary
public int doFinal(byte[] output, int outOff)

Implements org.bouncycastle.crypto.Digest.doFinal.

Doc from org.bouncycastle.crypto.Digest.doFinal.

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

Parameters
output:byte[]

the array the digest is to be copied into.

outOff:int

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

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

Implements org.bouncycastle.crypto.Xof.doFinal.

Doc from org.bouncycastle.crypto.Xof.doFinal.

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

Parameters
output:byte[]

output array to write the output bytes to.

outOff:int

offset to start writing the bytes at.

outLen:int

the number of output bytes requested.

Returns:int

the number of bytes written

Annotations
@Override
doOutputback to summary
public int doOutput(byte[] output, int outOff, int outLen)

Implements org.bouncycastle.crypto.Xof.doOutput.

Doc from org.bouncycastle.crypto.Xof.doOutput.

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.

Parameters
output:byte[]

output array to write the output bytes to.

outOff:int

offset to start writing the bytes at.

outLen:int

the number of output bytes requested.

Returns:int

the number of bytes written
