The method is called DigestSearch because it USES the unique digest (one-way hash) value to represent a search word.

该方法称作DigestSearch是因为它使用惟一摘要(单向散列)值来表示一个搜索字。

Message digests are secure one-way hash functions that take arbitrary-sized data and output a fixed-length binary hash value.

消息摘要是安全的单向哈希函数，它可以接受任意大小的输入数据，并输出固定长度的二进制哈希值。

Message Digests are secure, one-way hash functions that convert arbitrary length data into fixed-length check sum / hash code.

消息摘要是一个安全的、单向的哈希函数，把任意长度的数据转化成固定长度的校验和/哈希码。

Delegates have been in Barcelona all week to hash out a plan that would pave the way for 192 nations to sign a legally binding international climate deal next month.

VOA: standard.2009.11.06

Well the idea of a hash, in fact, what's called a hash function is to have some way of mapping any kind of data into integers.

我要怎么做？实际上想法还是哈希,通过一个哈希函数,把任何种类的数据都映射成整数。

So let's look at the second example, all right, I keep doing that -- this piece of code from here to here gives me a way of now creating a hash table of size 256.

所以让我们来看一下第二个例子，好的，我继续做那件事,这段代码中从这里到这里,是创建一个大小为256的哈希表。

Memories are not held in their entirety in the brain like old movie clips, but are maintained as a kind of chemical residue of the original perception, which could be thought of as a hash value or remainder, but not a one-way algorithm at all.
