Robust checksum algorithms like MD5 and SHA do much more than simply take the remainder when dividing by 256.
健壮的校验和算法如md5和SHA并不仅仅取其除以256的余数,它完成的要多得多。
If I use SHA accent to exchange with Shanghainess, they will treat me as their brother. But I speak mandarin or Hangzhou accent; I will get their bad treatment.
