python判断密码连续，重复，大小写、数字、符号混合密码复杂度要求

一、python 判断密码连续，重复，大小写、数字、符号混合密码复杂度要求

1. 运行环境

python 3.6.8

2. 密码必须包含大小写、数字、特殊符号中的3种且长度为8-16位

def verifyPassword(pwd: str):
    '''
	验证密码复杂度要求,密码必须由大小写字母、数字和特殊字符!@#$%^&*组成
	pwd: 要验证的密码
	'''
    # 必须4种全部包含
    # pattern = r'^(?=.*[0-9])(?=.*[A-Z])(?=.*[a-z])(?=.*[!@#$%^&*,\.])[0-9a-zA-Z!@#$%^&*,\\.]{8,16}$'

    # 包含3种即可
    pattern = r'^(?![a-zA-Z]+$)(?![A-Z0-9]+$)(?![A-Z\W_]+$)(?![a-z0-9]+$)(?![a-z\W_]+$)(?![0-9\W_]+$)[a-zA-Z0-9\W_]{8,16}$'
    res = re.search(pattern, pwd)
    return True if res else False

3. 密码不能3位及以上连号字母或数字

def isSeries(pwd: str, seriesCount: int = 3):
    '''
    判断密码是否连续
    pwd: 密码
    seriesCount: 连续个数
    '''
    if pwd and (len(pwd) > 0):
        # 自身算起
        ascSeriesCount = 1
        descSeriesCount = 1
        # 存在顺序型的连续性的字符串
        for i in range(len(pwd)):
            currentCharCode = pwd[i]
            if i == 0:
                prevCharCode = ""
            else:
                prevCharCode = pwd[i - 1]
                if currentCharCode == chr(ord(prevCharCode) + 1):
                    ascSeriesCount += 1
                    if ascSeriesCount == seriesCount:
                        return True
                else:
                    ascSeriesCount = 1

        # 存在逆序性的连续性的字符串*/
        for i in range(len(pwd)):
            currentCharCode = pwd[i]
            if (i - 1) >= 0:
                prevCharCode = pwd[i - 1]
            else:
                prevCharCode = ""
            if chr(ord(currentCharCode) + 1) == prevCharCode:
                descSeriesCount += 1
                if descSeriesCount == seriesCount:
                    return True
            else:
                descSeriesCount = 1
    return False

4. 密码不能连续3个及以上重复字符

def isRepeat(pwd: str, repeatCount: int = 3):
    '''
    判断密码是否包含重复字段
    '''
    if pwd and (len(pwd) > 0):
        ascRepeatCount = 1
        for i in range(len(pwd)):
            currentChar = pwd[i]
            if i == 0:
                prevChar = ""
            else:
                prevChar = pwd[i - 1]
            if currentChar == prevChar:
                ascRepeatCount += 1
                if ascRepeateCount == repeatCount:
                    return True
            else:
                ascRepeatCount = 1
    return False

{'asd000qweh': True}
============End================

5. 密码不能包含姓名大小写全拼

# 该方法需要引入pypinyin包
from pypinyin import lazy_pinyin

def isContainsName(pwd: str, name: str):
    '''
    判断密码中是否包含名称大小写全拼
    pwd: 密码
    name: 名称汉字
    '''
    if name == None or name == '':
        return False
    
    nameArr = lazy_pinyin(name)
    pinyinName = ''.join(nameArr)
    for item in nameArr:
        pinyinName += item
    if pwd.lower().__contains__(pinyinName.lower()):
        return True
    else:
        return False

测试结果

pwd = 'zhangsan6123'

============Start================
{'zhangsan': True}
{'张三': True}
{'lisi': False}
{'李四': False}
{'': False}
============End================

6. 汉字转拼音

# 该方法需要引入pypinyin包
from pypinyin import lazy_pinyin
nameArr = lazy_pinyin(item)
