These tools work by using hashes (for example, "#tab3") to alter the URL without loading a new page.

这些工具使用哈希值（例如，“#tab3”）改变 URL，而无需加载一个新页面。

As mentioned earlier, messages and certificates make use of cryptographic hashes to verify integrity.

正如前面所提到的那样，消息和证书使用加密哈希来验证完整性。

Groovy allows iteration to work for all kinds of collections, including hashes, as shown in Listing 2.

Groovy支持各种集合的迭代工作，包括哈希，如清单2所示。

Hashes and symbols - using hashes and symbols make it easy to express relationships and identify objects.

Use the rpm command to install the package with flags for verbose output and hashes (#) to show progress.

使用 rpm 命令安装包，用标记表示详细输出和（#）表示进度的井号。

This is especially true if you need to process complex command-line switches to create multi-level hashes.

这对于您需要处理复杂的命令行开关以创建多层散列时尤为有用。

The loadMetaPhones subroutine is straightforward code that creates two hashes of metaphone keys and values.

loadmetaphones子例程是创建变音位关键字和值的两个散列的简单代码。

Have configurations nested more than one layer deep (up to one layer can be handled with the AppConfig hashes).

具有多于一层深度的嵌套配置(直到可以被appconfig散列处理的一层)。

The md5() function hashes whatever string is fed to it and turns it into a 32-character fixed-length string.

md5() 函数可以散列反馈的任何字符串，并将其转变为固定长度为 32 个字符的字符串。

This means that you need a solid understanding of the interaction of references, hashes, and arrays in Perl.

这意味着需要充分了解引用、散列和数组在Perl中的交互作用。

The other argument mitigating the potential severity of this attack is actually derived from the use of hashes.

减小这种攻击的潜在严重性的另一个争论实际上源于散列的使用。

Blocks - blocks encapsulate executable logic, and allow the logic to be stored (in hashes) for later execution.

Block——Block可以封装可运行逻辑，并允许逻辑储存起来(置于Hash中)，用于稍后执行。

Perhaps the biggest complaint with NTLMv2 created hashes is that Windows does not utilize a technique called salting.

对于使用NTLMv 2创建的哈希，可能最大的不足在于Windows无法使用一种名为Salting的技术。

They also have some built-in data structures like arrays, hashes, and some sort of support for record-like structures.

它们还有一些内嵌的数据结构，像数组、哈希表和对像记录一样的结构的某种支持。

For layered configurations, AppConfig needs to have custom functions installed to interpret hashes deeper than one level.

对于分层配置，AppConfig需要安装有定制函数，以解释不止一层深的散列。

That's why you should never rely on hashes alone — always add some salt to your hash so the resulting hash values are unique.

这就是为什么你无论何时都不该仅仅依赖hash——永远给hash加些salt以获得独一无二的hash结果值。
