NodeJs安全性-从数据库读取散列的sha256密码

Question

I know how to "safely" store a password in the database in NodeJs and use it as a user login for example. But know I have a different question, where I'm not sure what might be best practice.

I am using amazon product api, so I have to provide different aws Id's. So I thought, storing them as a plain text might not be that sure, so I hashed them.

But when sending my request to the amazon Api via the code snipped below, I somehow have to safely restore the "correct key", because the hashed one will not be accepted then.

var opHelper = new OperationHelper({
    awsId:     'XXXXX',
    awsSecret: 'XXXXX',
    assocId:   'XXXX'
});

Is there some opposite way of

crypto.createHash('sha256').update(awsId).digest('base64')

So to make my it more clear, how to restore a hashed key from my database so that I can use it in the amazon request again?

Or am I getting things totally wrong and I do not have to store them hashed in my database?

Thank you for letting me know

Answer 1

There is no way to reverse a hash without brute force.

This is the point of a hash.
