Method

voidzero(byte[] a, int aoffset, int len)
zero 
fill((byte) 0, a, aoffset, len);
voidzero(byte[] bytes, int off, int len)
Zeroes all bytes between off (inclusive) and off + len (exclusive) in the given array. 
int remaining = len;
while (remaining > ARRAY_LEN) {
    System.arraycopy(ZERO_ARRAY, 0, bytes, off, ARRAY_LEN);
    off += ARRAY_LEN;
    remaining -= ARRAY_LEN;
System.arraycopy(ZERO_ARRAY, 0, bytes, off, remaining);
voidzero(byte[]... arrays)
zero 
for (byte[] ba : arrays)
    set(ba, 0, ba.length, (byte) 0);
voidzero(double[] zero)
Sets every value of the passed array to 0. 
for (int k = 0; k < zero.length; k++) {
    zero[k] = 0;
long[]zero(int bits)
Allocate a new long[]. 
return new long[((bits - 1) >>> LONG_LOG2_SIZE) + 1];
Stringzero(int x)
zero 
String s = Integer.toHexString(x & 0xFF);
if (s.length() == 1)
    return "0" + s;
else
    return s;
byte[]zero_pad(byte[] original, int block_size)
Return a new array equal to original except zero-padded to an integral mulitple of blocks. 
if ((original.length % block_size) == 0) {
    return original;
byte[] result = new byte[round_up(original.length, block_size)];
memcpy(result, 0, original, 0, original.length);
return result;
StringzeroAlign(String x, int count)
zero Align 
if (x.length() < count) {
    int spaces = count - x.length();
    StringBuilder result = new StringBuilder(count);
    while (spaces > 0) {
        result.append("0");
        spaces--;
    result.append(x);
...
intzeroBasedTemplateStart(final int[] actions)
Zero-based start position on template. 
return actions[TEMPLATE_START_INDEX];
voidzeroBlock(byte[] block, int off, int len)
zero Block 
for (int i = off; i < off + len; ++i)
    block[i] = 0;
