自Java 1.7.0_06版本起,String类有了第二个哈希函数:hash32。该方法目前还不是公有的,只能通过使用反射机制或者是调用sun.misc.Hashing.stringHash32(String)来访问该方法。只有当那7种哈希相关的JDK容器的大小超过系统变量jdk.map.althashing.threshold所设定的阀值时,该方法才会被使用。这是一个试验性质的功能,...
Infine, non usare il codice hash anziché un valore restituito da una funzione di hashing crittografico se è necessario un hash crittografico sicuro. Per gli hash crittografici, usare una classe derivata dallaSystem.Security.Cryptography.HashAlgorithmclasse oSystem.Security.Cryptography.KeyedHash...

Finally, don't use the hash code instead of a value returned by a cryptographic hashing function if you need a cryptographically strong hash. For cryptographic hashes, use a class derived from theSystem.Security.Cryptography.HashAlgorithmorSystem.Security.Cryptography.KeyedHashAlgorithmclass. ...
