public int processBytes(byte[] in, int inOff, int len, byte[] out, int outOff) throws DataLengthException Implements org.bouncycastle.crypto.StreamCipher.processBytes. Doc from org.bouncycastle.crypto.StreamCipher.processBytes. process a block of bytes from in putting the result into out. Parameters in:byte[] the input byte array. inOff:int the offset into the in array where the data to be processed starts. len:int the number of bytes to be processed. out:byte[] the output buffer the processed bytes go into. outOff:int the offset into the output byte array the processed data starts at. Returns:int the number of bytes produced - should always be len. Exceptions DataLengthException: if the output buffer is too small.

processBytes

public int processBytes(byte[] in, int inOff, int len, byte[] out, int outOff) throws DataLengthException

process a block of bytes from in putting the result into out.

Parameters

in:byte[]: the input byte array.
inOff:int: the offset into the in array where the data to be processed starts.
len:int: the number of bytes to be processed.
out:byte[]: the output buffer the processed bytes go into.
outOff:int: the offset into the output byte array the processed data starts at.

Returns:int

the number of bytes produced - should always be len.

Returns:byte the result of processing the input byte.

returnByte

public final byte returnByte(byte in)
