The list of methods to do Byte Array Rotate are organized into topic(s).

Method

byte[]rotateLeft(byte[] input)
Moves all bytes one up, meaning the left most byte (0) is swapped to the end 
byte[] cycled = new byte[input.length];
System.arraycopy(input, 1, cycled, 0, input.length - 1);
cycled[cycled.length - 1] = input[0];
return cycled;
byte[]rotateRight(byte[] input)
Moves all bytes one down, meaning the right most byte (length-1) is swapped to the beginning 
byte[] cycled = new byte[input.length];
System.arraycopy(input, 0, cycled, 1, input.length - 1);
cycled[0] = input[input.length - 1];
return cycled;
byte[]unrotate(byte[] data, int blockSizeBytes)
Unrotate data. 
byte result[] = new byte[data.length];
int numBlocks = data.length / blockSizeBytes;
for (int block = 0; block < numBlocks; block++) {
    for (int el = 0; el < blockSizeBytes; el++) {
        result[el * numBlocks + block] = data[block
                * blockSizeBytes + el];
return result;
