• python 应用 base64、hmac、hashlib包实现:MD5编码 base64编码解码、SHA256编码、urlsafe_b64encode编码等等基本所有的加密签名的方法


    用python做HTTP接口自动化测试的时候,接口的很多参数是经过各种编码加密处理后在传到后台的,这里列举出python实现 应用 base64、hmac、hashlib包实现:md5编码 sha1编码  sha3_224编码  sha3_256编码  sha3_384编码  sha3_512编码 、 sha224编码 、 sha384编码 、 sha512编码  、shake_128编码 、 shake_256 编码 、urlsafe_b64encode编码等各种编码加密签名的方法

    
    
    import base64
    import hmac
    import hashlib
    
    # MD5 编码 应用haslib
    user = 'username'
    pwd = 'pass123456'
    
    user = user.encode(encoding='utf-8')
    pwd = pwd.encode(encoding='utf-8')
    user_MD5 = hashlib.md5(user).hexdigest()
    pwd_MD5 = hashlib.md5(pwd).hexdigest()
    
    print('user_MD5:', user_MD5)
    print('pwd_MD5:', pwd_MD5)
    
    #  MD5 编码含有中文
    # 如果有中文中文字符在Python中是以unicode存在的,同一个字符串在不同的编码体系下有不同的值,所以在hash前要进行编码需要转为gb2312
    # 这样才可能跟其他工具的编码一样(当然具体转为那种编码,前后端需要统一即可)
    
    user = '张三as'
    pwd = 'a小四a'
    
    user = user.encode(encoding='gb2312')
    pwd = pwd.encode(encoding='utf-8')
    user_MD5 = hashlib.md5(user).hexdigest()
    pwd_MD5 = hashlib.md5(pwd).hexdigest()
    
    print('张三as:', user_MD5)
    print('a小四a:', pwd_MD5)
    
    # hashlib的编码:md5 sha1 sha3_224 sha3_256 sha3_384 sha3_512 sha224 sha384 sha512 shake_128 shake_256
    a = "hello word"
    a = a.encode(encoding='utf-8')
    print('hello word:md5 = ', hashlib.md5(a).hexdigest())
    print('hello word:sha1 = ', hashlib.sha1(a).hexdigest())
    print('hello word:sha224 = ', hashlib.sha224(a).hexdigest())
    print('hello word:sha256 = ', hashlib.sha256(a).hexdigest())
    print('hello word:sha384 = ', hashlib.sha384(a).hexdigest())
    print('hello word:sha512 = ', hashlib.sha512(a).hexdigest())
    
    
    # base64 编码
    string = 'helloWord'
    byteString = string.encode(encoding='utf-8')
    base64String = base64.b64encode(byteString)
    print("base64String :", base64String)  # 这个时候base64String 是byte型的,需要转化为str
    base64String = base64String.decode()
    print("base64String.decode :", base64String)  # 现在 才是str型的
    
    # base64 解码
    
    decodestr = base64.b64decode(base64String)
    print('decodestr:', decodestr)
    print("decodestr.decode:", decodestr.decode())
    
    
    # SHA256编码
    string = '123456'
    byteString = string.encode(encoding='utf-8')
    print(byteString)
    
    sha256str = hashlib.sha256(byteString).hexdigest()
    # 把小写转换为大写
    sha256str = sha256str.upper()
    print("sha256str:", sha256str)
