salt encryption

We know that if the password is hashed directly, then the hacker can get a hash value by obtaining this password, and then by checking the hash value dictionary (for example, MD5 password cracking site), the password of a user.Adding salt can solve

1 backgroundThe system involved in authentication needs to store the user's authentication information, the commonly used user authentication method mainly is the user name and the password way, in order to be safe, the user input password needs to

The first time I heard about the value of salt encryption, it always feels strange. Because it is always associated with salty, the association of the password is salty.in fact, the salt mentioned here, simply said, is a set of safe random numbers.

I. State the Workflow:1. According to the existing password string to generate a password + salt string, You can also store the salt of the encrypted string in the database (see requirements),2. Verify that the submitted password string is encrypted

Adding salt is a way to increase the file encryption strength. We know that encryptionAlgorithmThe longer the user password, the stronger the encryption strength (when the user password is fully utilized). In fact, the so-called "salt" is to

Salt encryption is to mix a random string into the encryption. this string is called & quot; salt value & quot ;, here, let's take a look at the usage of the salt-based hash encryption and verification functions in the Python Flask

MD5 encryption (or digest algorithm) Everyone is familiar with it, and it doesn't explain.Now a lot of database design like to use one-way encryption to save the password, verify that the password is encrypted once again to do a ciphertext

This article will explain to you how to use Node.js the Crypto module to add salt to your password hash . Here, we will not make a detailed comparison of the password storage methods that we do not understand. What we are going to do is to know the

A simple md5 and salt encryption method (to prevent rainbow tables from hitting the database) Md5 encryption (or digest algorithm) is not explained if you are familiar with it. Currently, many database designs prefer to use one-way encryption to
