MD5 is not a reversible function. Further, no one-way hash should be a reversible function.

MD 5不是可逆的功能。进一步，没有单向散列应该是一个可逆的功能。

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。

The existing one-way hash functions without trapdoor are all iterative algorithms, for instance, MD and SHA family, etc.

现有的无陷门单向散列函数都是迭代算法，例如SHA和MD系列算法等。

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.

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.
