推荐答案

您无法解码md5散列，因为散列是最好被认为是

You cannot decode an md5 hash, as hashing is a process that is best thought of as one-way encoding (that is to say what is hashed cannot be de-hashed; one can only determine what was hashed, either by examining a list of known hashes, or by hashing a set of inputs and matching the resulting hashes with the hash you are trying to "decode").

引用Wikipedia，这种哈希算法的主要特征是:

Quoting Wikipedia, the key features of such a hashing algorithm are:

找不到消息是不可行的 具有给定的哈希值

it is infeasible to find a message that has a given hash,

是 无法修改消息而没有 更改其哈希，

it is infeasible to modify a message without changing its hash,

这是不可行的 用找到两个不同的消息 相同的哈希值.

it is infeasible to find two different messages with the same hash.

如今，此类算法最常见的用途是:

The most common uses of such algorithms today are:

• 存储密码
• 验证文件的内容.

如果要对数据进行双向加密，则需要查看其他Python加密库(通常，Stackoverflow的

If you want to two-way encrypt the data, you need to look at other cryptographic libraries for Python (As usual, Stackoverflow has a recommendation).
