主要是这一段不明白，求解

// 通过TEA算法加密信息
public String encryptByTea(String info) {
byte[] temp = info.getBytes();
int n = 8 - temp.length % 8; //若temp的位数不足8的倍数,需要填充的位数
byte[] encryptStr = new byte[temp.length + n];
encryptStr[0] = (byte) n;
System.arraycopy(temp, 0, encryptStr, n, temp.length);
byte[] result = new byte[encryptStr.length];
for (int offset = 0; offset < result.length; offset += 8) {
byte[] tempEncrpt = encrypt(encryptStr, offset, KEY, 32);
System.arraycopy(tempEncrpt, 0, result, offset, 8);
}
String tmp = encryptTwo(result);
// for (int i = 0; i < result.length; i++) {
// tmp = tmp + result[i] + this.separator;
// }
return tmp;
}
