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

Overrides org.bouncycastle.crypto.fips.SHAKEDigest.doOutput.

Implements org.bouncycastle.crypto.internal.Xof.doOutput.

Doc from org.bouncycastle.crypto.internal.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
out: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
