Unfortunately, however, in many projects this is still neglected and passwords in the database are kept clear. Sometimes it is enough to encrypt / hash users’ passwords, other times it is necessary to encrypt much more information. You can install it with one of the below commands: NPM:īcrypt.Every time we propose a new project, there are recurring requirements, such as modularity, security, internationalization… Associated with the requirement of security, as well as data confidentiality, is the concealment of information in the database (so that it cannot be read by anyone who has access to it). If needed, we wrote a guide on installing Node.js.īefore we can start writing our code, we need to install the bcrypt.js NPM package. Therefore it keeps up with Moore's law, so as computers get faster you can increase the work factor and the hash will get slower to brute force.īefore moving forward, make sure you have Node.js installed and an application directory setup for our code. how long it takes to decrypt it by brute force measures). It incorporates hash encryption along with a work factor, which allows you to determine how expensive the hash function will be (i.e.

In this article, we'll walk through how to hash a password using the Node.js implementation of Bcrypt called bcrypt.js.īcrypt is one of the most used encryption libraries today. If you generate your hashes correctly, both methods would take a hacker lots of time and tons of computing power to complete. Or use a rainbow table of matched hashes. The only way to find the password or message that produces a given hash is to attempt a brute-force-search of possible inputs to see if they produce a match. If your database gets hacked in this case, the hacker will be left with random hash strings instead of plain text ones they could use to easily exploit your user's accounts with. Later on, you can compare the hash and password to verify that they match. The answer is to generate a hash (a long, complex, and unique string) using the user's password and store that hash in your database. Since it's a big no-no to store passwords as plain text in your database, how are you supposed to handle and store them?

Chances are that you'll need to handle people's passwords in your coding endeavors.
