What is BCrypt and Why Should We Use It?


In the world, passwords play a critical role in keeping your data and other important information safe. Therefore, it is very important to keep your passwords safe. If not, the consequences could be catastrophic.

Hashed password solutions are inadequate

Many encryption algorithms aren't good enough and put your data and resources at risk. Let's look at a few instances.

Plain text passwords

When the name is breached, the plain text password uses only letters. If a hacker accesss such passwords, it can easily appear as a user on your system. Most of the time, plain text passwords are replicated across other entries, because users don't have to remember multiple passwords for different sites or apps. This only gives a hacker access to these applications.

Hash Encryption

The Hash algorithm does not store plain text passwords to verify user identity with a password. Here, a hash algorithm is applied to make a password more secure. In theory, while this is a much better password solution, hackers have found ways within this system, because the algorithm used is not exactly a one-way option. In fact, hackers can still estimate passwords until they access your resources.

BCrypt Solution

So, is there a solution for the correct password encryption? Anything that will protect your valuable data and resources, no matter what? Yes, i do! Designed by Niels Provos and David Mazières in 1999, BCrypt comes in the form of hashing function.

BCrypt is based on the Blowfish block encryption encryption algorithm and takes the format of an adaptive hash function. But why use it to protect your data and resources? We're going to need some technical information to explain...

BCrypt can set hash using a Key Factor. With Key Factor changes, hash output may be affected. In this way, BCrypt remains extremely resistant to attacks, a type of decryption, especially called a rainbow table.

This Key Factor will continue to be an important feature as computers become stronger in the future. Why? Because it compensates for powerful computers and significantly slows down the hash speed.

If you have sensitive data or information to protect, it's very important to make sure it's safe in the right way. As we have seen, there are many ways to secure this information through a variety of password methods, but only BCrypt offers a really robust solution.
