使用 hashlib 进行 Python 密码散列

[英]Python Password Hashing with hashlib

原文 2021-07-04 05:35:45 5 1 python/ hash/ hashlib/ login-system

I'm trying to hash a password for a login system I am creating.我正在尝试为我正在创建的登录系统散列密码。 I am using the hashlib import and using the blake2b hash algorithm.我正在使用 hashlib 导入并使用 blake2b 哈希算法。 I can't seem to figure out how to hash a variable such as passwordEntry .我似乎无法弄清楚如何散列诸如passwordEntry 之类的变量。 All the hashlib examples are just of blake2b hashing characters.所有 hashlib 示例都只是 blake2b 散列字符。 For example: blake2b(b'IWantToHashThis') I am quite confused on why the "b" letter has to be included in the hash.例如： blake2b(b'IWantToHashThis')我很困惑为什么“b”字母必须包含在哈希中。 If I try to hash a variable the "b" letter can't be concluded with the variable I want to hash.如果我尝试散列一个变量，则“b”字母不能与我想要散列的变量结束。 Example of me trying to hash a variable: blake2b(passwordEntry) Another example of me trying to hash the variable: blake2b(b passwordEntry) On the second example I just gave hashlib thinks that it is trying to hash the variable "b passwordEntry."我试图对变量进行散列的示例： blake2b(passwordEntry)我试图对变量进行散列的另一个示例： blake2b(b passwordEntry)在第二个示例中，我刚刚给 hashlib 认为它正在尝试对变量“b passwordEntry”进行散列。 Like I said before the "b" letter has to be included in the hashing algorithm for it to preform correctly.就像我之前所说的那样，散列算法中必须包含“b”字母才能正确执行。 Sorry for the long question if it is hard to follow I understand .如果很难理解，我很抱歉这个长问题。

The letter b only works before quotes, [ " , ' , """ , '''' ].字母b仅在引号前有效，[ " , ' , """ , '''' ]。 And it is there to notate that this string is bytes .并且要注意这个字符串是bytes 。 If you want to convert your string to bytes you can do that by b"string" or "string".encode() .如果要将字符串转换为字节，可以通过b"string"或"string".encode() 。 However, in your case you can only use the encode() method of str since b only works for Literal Strings.但是，在您的情况下，您只能使用str的encode()方法，因为b仅适用于文字字符串。 So in your case it will be blake2b(passwordEntry.encode())所以在你的情况下它将是blake2b(passwordEntry.encode())
