Question

所以我使用this SO answer中的代码创建了一个双向字母数字加密函数。

基本上，函数看起来像这样：

from Crypto import Random
from Crypto.Cipher import AES

from binascii import hexlify
from binascii import unhexlify

def encrypt_password(self, password):
    key = current_app.config['VAULT_KEY']
    iv = Random.new().read(AES.block_size)
    cipher = AES.new(key.strip("\'"), AES.MODE_CFB, iv)
    self.password_encrypted = hexlify(iv + cipher.encrypt(password))

def decrypt_password(self):
    key = current_app.config['VAULT_KEY']
    encrypted = unhexlify(self.password_encrypted)
    cipher = AES.new(key.strip("\'"), AES.MODE_CFB, encrypted[:AES.block_size])
    return cipher.decrypt(encrypted)[AES.block_size:]

这些函数与数据库对象交互，保存encrypt_password的结果;要解密，使用decrypt_password。（相当不言自明。）

我被困在这条线上：

encrypted = unhexlify(self.password_encrypted)

不知何故，Python一直告诉我self.password_encrypted不是十六进制数字。我不知道b / c上的内容是以十六进制数字的形式保存到对象中。

顺便说一下，字符串表示是：'\x[decimal numbers]'我认为这很奇怪。难道不是十六进制数字吗？

跟踪跟踪：

好的，所以我对你发布的文件做了一些修改......

CustomerToTeamTemplate customerToTeamTemplate = new CustomerToTeamTemplate(this.Context);

//Relation to CustomerToClients
new ReportRelationMapping
{
    LocalRelation = this.customerMapper.GetForeignRelation(x => x.Id, this.ReportRelationsMappings),
    ForeignRelation = this.customerToTeamMapper.GetForeignRelation(x => x.CustomerId, customerToTeamTemplate.ReportRelationsMappings),
},

But this isn't working for me because I am creating an infinate loop when passing this.ReportRelationsMappings to it self.

它可能与您的环境键变量有关，请确保它符合16,24或32字节构造。对于AES初始化第一个参数。

关于'\ x {0-9a-fA-f} {0-9a-fA-f}'格式，据我所知，这是一种字符串格式的十六进制输出
