JAVA 密码弱口令检测机制

最近做项目需求,遇到客户要求对密码弱口令,进行检查和判断,具体要求如下:
	1,口令长度应大于等于8个字符,
	2,口令应由大写、小写、数字、特殊字符三者及以上组成
	3,不得使用一串相同的数字或字母组成
	4,不能键盘连续序列集合
	5.,,,,,,
	废话不多说,直接上代码:
	首先配置文件,便于以后修改:
#保护系统级别 系统级别分为二级系统和三级系统
#当systemGrade不为2或者3时,系统默认使用系统级别2的规则
#当systemGrade设置为2或者3时,其他选项若未配置,则按照默认值处理,具体默认值信息见每一项说明
systemGrade=2

#检测密码口令长度
#当checkPasswordLength为disable时,下面两项设置无效
#其他检测功能设置为disable时,对应设置项设置数据无效
#当系统级别为2或3时,checkPasswordLength默认为enable
#当系统级别为2或3时,limitPassMinLength默认为8,limitPassMaxLength默认为20
#是否检测密码口令长度,如为enable则检测,如为disable则不检测,如为空,
checkPasswordLength=enable
#允许密码口令最小长度
limitPassMinLength=8
#允许密码口令最大长度,如为空,则不设置上限
limitPassMaxLength=20

#是否包含数字、小写字母、大写字母、特殊符号
#当设置checkContainUpperLowerCase为enable时,区分大小写
#当系统级别为2时:checkContainDigit默认为enable,checkContainUpperLowerCase默认为disable
#当系统级别为2时,checkContainLowerCase默认为disable,checkContainUpperCase默认为disable
#当系统级别为2时,checkContainSpecialChar默认为disable
#当系统级别为3时:checkContainDigit默认为enable,checkContainUpperLowerCase默认为disable
#当系统级别为3时,checkContainLowerCase默认为disable,checkContainUpperCase默认为disable
#当系统级别为3时,checkContainSpecialChar默认为enable
#是否检测包含数字
checkContainDigit=enable
#是否检测包含大小写字母,区分密码口令大小写
checkContainUpperLowerCase = enable
#是否检测包含小写字母
checkContainLowerCase = enable
#是否检测包含大写字母
checkContainUpperCase = enable
#是否检测包含特殊符号
checkContainSpecialChar=enable
#支持自定义特殊符号集合
specialCharSet="!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~"

#检测键盘按键连续 比如qwer、1qaz、0okm等
#允许横向最大连续num为7,最小为3
#允许斜向最大连续num为4,最小为3
#当系统级别为2时:checkHorizontalKeySequential默认为enable,horizontalKeyLimitNum默认为4
#当系统级别为2时,checkSlopeKeySequential默认为enable,slopeKeyLimitNum默认为4
#当系统级别为3时:checkHorizontalKeySequential默认为enable,horizontalKeyLimitNum默认为3
#当系统级别为3时,checkSlopeKeySequential默认为enable,slopeKeyLimitNum默认为3
#是否检测键盘横向连续 
checkHorizontalKeySequential=enable
#允许键盘横向连续最小数值,如为空,则设置为默认值
horizontalKeyLimitNum=3
#是否检测键盘斜向连续
checkSlopeKeySequential=enable
#允许键盘斜向连续最小数值,如为空,则设置为默认值
slopeKeyLimitNum=3

#检测逻辑位置连续 比如1234、abcd等
#当系统级别为2时,checkLogicSequential默认为enable,logicLimitNum默认为4
#当系统级别为3时,checkLogicSequential默认为enable,logicLimitNum默认为3
#是否检测逻辑位置连续
checkLogicSequential=enable
#允许逻辑位置连续最小数值,如为空,则设置为默认值
logicLimitNum=3

#检测相邻字符相同 比如aaaa、2222、@@@@等
#当系统级别为2时,checkSequentialCharSame默认为enable,sequentialCharNum默认为4
#当系统级别为3时,checkSequentialCharSame默认为enable,sequentialCharNum默认为3
#是否检测相邻字符相同
checkSequentialCharSame=enable
#允许相邻位置相同最小连续数,如为空,则设置为默认值
sequentialCharNum=3

其次增加一个配置类:

最后 进行测试一下吧:

boolean b1 = CheckPwdUtils.EvalPWD(SYS_USER_PASS);
		if(!b1){
			System.out.println("对不起,该密码安全等级比较低,请修改");
		}
