/**
|
||||
* BCrypt加密算法实现。由它加密的文件可在所有支持的操作系统和处理器上进行转移。它的口令必须是8至56个字符，并将在内部被转化为448位的密钥。
|
||||
* <p>
|
||||
* 此类来自于https://github.com/jeremyh/jBCrypt/
|
||||
* <p>
|
||||
* 使用方法如下：
|
||||
* <p>
|
||||
* {@code
|
||||
* String pw_hash = BCrypt.hashpw(plain_password, BCrypt.gensalt());
|
||||
* }
|
||||
* <p>
|
||||
* 使用checkpw方法检查被加密的字符串是否与原始字符串匹配：
|
||||
* <p>
|
||||
* {@code
|
||||
* BCrypt.checkpw(candidate_password, stored_hash);
|
||||
* }
|
||||
* <p>
|
||||
* gensalt方法提供了可选参数 (log_rounds) 来定义加盐多少，也决定了加密的复杂度:
|
||||
* <p>
|
||||
* {@code
|
||||
* String strong_salt = BCrypt.gensalt(10);
|
||||
* String stronger_salt = BCrypt.gensalt(12);
|
||||
* }
|
||||
*
