推荐答案

你不能。

SHA不是一种加密算法 - 它是一种散列算法，并且存在巨大的差异：如果你有解密密钥，则可以反转加密，哈希不能。[br / >


Hashing抛弃无法恢复的信息 - 它不会对信息进行加密。



如果你已经哈希了数据和需要恢复它 - 你不能。这就是整个想法。

You can't.
SHA is not an encryption algorithm - it's a hashing algorithm, and there is a huge difference: encryption can be reversed if you have the decryption key, hashing cannot.

Hashing throws away information, which cannot be recovered - it does not encrypt information.

If you have hashed your data and need to recover it - you can't. That is the whole idea.
