Beyond the basic storage of data , hashes are also important in distributed systems .

除了在数据储存中的应用外，哈希表在分布式系统中的应用也是非常重要的。

The important thing is how hashes work and how to tune them for maximum performance benefit .

所以最关键的是哈希函数是如何运行的，并怎样才能使其发挥最大的效用。

Hashes are statistically unique ; a different two-byte sequence will not hash to the same value .

哈希在统计上是唯一的；不同的双字节序列不会哈希为同一个值。

For hackers around the world , the huge trove of new leaked passwords is an opportunity to update their " rainbow tables " - vast databases that serve as a digital key for cracking encrypted passwords , called " hashes . "

对于全世界的黑客来说，大批量泄漏的密码正好可以拿来更新他们所谓的“彩虹表（rainbowtable）”巨大的数据库，可作为破解加密密码的数字钥匙，称之为“哈希（hash）”。

Avoid subscripting arrays or hashes within loops .

避免在循环中使用下标数组或散列。
