Hash-based Message Authentication CodeIn cryptography, a keyed-hash message authentication code (HMAC) is a specific construction for calculating a message authentication code (MAC) involving a cryptographic hash function in combination with a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data integrity and the authentication of a message.

英汉例句

• each hash function can produce collisions; in other words, two different input values can have the same hash code h(x).

  每个hash函数可能产生沖突；换句话说，两个不同的输入值可能具有相同的hash码h(x)。

• the hash code entered is invalid. try importing a hash code from an assembly.

  输入的哈希代码无效。请尝试从程序集导入哈希代码。

• if the object cannot be altered, then the hash code will never change either.

  如果对象不能被改变，那么哈希码也永远不变。

• returns a hash code for the given object, using a hashing algorithm that ignores the case of strings.

  使用忽略字符串大小写的哈希算法返回给定对象的哈希代码。

• for example, if you have three partitions, and your key’s hash code is 7, then 7 divided by 3 is 2, remainder 1, so the item goes in and comes from partition 1.

  例如，如果您有3 个分区，键的散列码为 7，7除以3得2余1，所以项应该位于分区1。

• furthermore, before the cm agent stores the object, it executes a query in the repository if the same hash code has already been stored.

  而且，在cm代理存储对象之前，它在储存库中执行一个查询，看储存库中是否已经存储了相同的散列码。

• these methods generate a case-insensitive instance of the collection using case-insensitive implementations of the hash code provider and the comparer.

  使用哈希代码提供程序和比较器的不区分大小写实现，这些方法为集合生成一个不区分大小写的实例。

• the key generator computes the hash code for the given string, and that hash code is stored in the db2-internal b-tree.

  键生成器计算给定字符串的hash码，这个hash码被存储在db2内部的b-树中。

• the hash code should provide a uniform distribution of values over the key space so that the partitions are evenly balanced.

  散列码应该在键空间上提供均匀的值分布，以便分区负载平衡。

• after the hash code has been computed once, getting the hash code for an internalized string is essentially free.

  一旦计算出了hash码，想获得一个内部化字符串的hash码实际上就轻而易举了。

• therefore, the properties play no role in determining whether two instances of the same type are equal or what the hash code value of the instance is.

  因此，在确定同一类型的两个实例是否相等或实例的哈希代码值是多少时，这些属性不起作用。

• if the (optional) single-instance-storage feature is turned on, an additional hash code (based on the mail content and other fields) must be generated.

  如果打开单事务存储特性（可选），那么必须生成一个附加的散列码（根据邮件内容和其他字段）。

• the way partitions really work is that a hash code is calculated on the key.

  分区的工作方式是对键计算散列码。

• the datatype class must provide some object representation of the type that the validator can use for equality comparison and hash code calculation.

  datatype类必须提供类型的某种对象表示，以便验证器可用来进行相等性比较和计算散列码。

• suppress the generation of a generic type parameter hash code and provide a legible type name instead.

  不要产生泛型类型参数的哈希值，使用一个易懂的类型名称作为替代。

• supplies a hash code for an object, using a hashing algorithm that ignores the case of strings.

  使用忽略字符串大小写的哈希算法，为对象提供哈希代码。

• with the help of the new hashcode() method of arrays, you can use it to generate a hash code for any local array types, instead of rolling your own each time you need it.

  在arrays的新方法hashcode()的帮助下，可以为任何本地数组类型生成哈希码，而不用在每次需要它的时候折腾您自己。

• the range producer computes the hash code for the given string to search for and returns a point range where the start and the end of the range is the hash code itself.

  范围生成器计算给定字符串的hash码，以搜索并返回一个点范围，这个范围的起始值和终止值是hash码本身。

• thus, all indexed strings with the same hash code are returned from the index scan as possible candidates.

  因此，索引扫描返回所有具有相同hash码的已索引的字符串，作为可能的候选者。

• if a key's hash code were to change while it was in a collection, some unpredictable and confusing consequences could follow.

  如果当关键字在集合中时它的散列代码被更改，那么将产生一些不可预测和容易混淆的结果。

• this hash code could be used as a key into a hashmap or for any other related purpose.

  这个哈希码可以用作hashmap或者其他相关目的的键。

• the hash code is an integer that should return a unique number of each unique key.

  散列码是一个整数，应该对每个键返回唯一的数字。
