Method

byte[]generateRandomBytes(int num)
This function generates a specified number of random bytes. 
byte[] randomBytes = new byte[num];
random.nextBytes(randomBytes);
return randomBytes;
byte[]generateRandomBytes(int num_to_generate)
generate Random Bytes 
Random random = new Random(System.currentTimeMillis());
byte[] id = new byte[num_to_generate];
random.nextBytes(id);
return id;
byte[]generateRandomBytes(int num_to_generate)
Generate a random array of bytes. 
byte[] id = new byte[num_to_generate];
RANDOM.nextBytes(id);
return id;
byte[]generateRandomBytes(int size)
generate Random Bytes 
Random rand = new Random();
byte[] arr = new byte[size];
rand.nextBytes(arr);
return arr;
byte[]getRandomByteArray(int len)
get Random Byte Array 
if (len < 0 || len > 256) {
    throw new IllegalArgumentException("Illegal length: " + len);
byte[] bytes = new byte[256];
for (int i = 0; i < 256; i++) {
    bytes[i] = (byte) i;
Random rand = new Random();
...
byte[]getRandomBytes()
get Random Bytes 
byte[] bytes = new byte[1024];
random.nextBytes(bytes);
return bytes;
byte[]getRandomBytes(int size)
Gets a byte array of length size with random bytes. 
byte[] bytes = new byte[size];
new Random().nextBytes(bytes);
return bytes;
byte[]getRandomBytes(int size)
Generates a random byte[] of given size. 
int len = size;
byte[] bigstuff = new byte[len];
random.nextBytes(bigstuff);
return bigstuff;
voidnextBytes(byte[] bytes)
next Bytes 
rand.nextBytes(bytes);
byte[]nextBytes(int count)

Creates an array of random bytes. 

byte[] result = new byte[count];
RANDOM.nextBytes(result);
return result;
