![]() ![]() An example of the bcrypt hashed password (iloveyou): $2y$12$nRhqyj7F4XMKotj4GQ5nheExNUnT/Xnne7ithB圓EzM83zbYNM13mĬonsidering the examples of the password hashing algorithms mentioned above, compared to MD5 and SHA-1, bcrypt is exponentially more secure as a password hashing algorithm. It is extremely slow to create a hash using bcrypt due to the extra salting creating the hash when compared to MD5 and SHA-1.bcrypt – The bcrypt password hashing algorithm using salting to calculate the hashed value of a password. Salting adds additional random characters to the first set of characters provided by the user, and then a hash is created. Bcrypt helps to protect passwords from so-called rainbow table attacks.SHA-1 – It stands for Secure Hash Algorithm and can have a 160-bit message digest size. SHA-1 is a much slower algorithm than MD5 but provides better security than MD5.An example of the MD5 hashed password (iloveyou): 8f3e13ff103d826b03821e53ce7ab05a.MD5 – This stands for Message Digest and can have 128 bits length of message digest content. It is a high-speed algorithm that provides relatively low security as a password hashing algorithm. An attacker only needs to perform 2^64 operations to find the identical hashes produced with MD5.To help appreciate the difference between hashing algorithms, let’s look at the following three: There are many different kinds of password hashing algorithms in use today. While the attacker can’t perform an “un-hash” of the hash, there is nothing to stop an attacker from trying password combinations to get the same password hash. Systems using password hashing get the same result each time with the same input (your password). With this knowledge, an attacker can use educated guesses and other tools to discover the password used to generate the password hash for an account. The attacker still has to figure out the original password used to create the hashed password. As mentioned, the hashing process transforms the data into random data other than the actual password. However, it is essential to stop and think about what password hashing is again. It is a one-way process that transforms your password into a hash value. When attackers execute a data breach and successfully exfiltrate databases or files containing hashed passwords, the passwords are not in their original format. If the two are the same, the password entered was the correct one. If they do not match, the user has entered an incorrect password. ![]() ![]() When an end-user performs a login with a password, their password’s resulting hash is checked with the actual hash value recorded by the system. The same mathematical formula compares the two hashes. When passwords are secured using a password hash, the password undergoes a one-way transformation from the original characters, making up the password into another string value: the hashed password. This transformation is made possible by mathematical algorithms used to calculate the hashed value of the end user’s password input. Again, this is a one-way transformation since it is impossible to “un-hash” or turn the password from the hashed value to the original password. Plain text passwords can be stored digitally, as well. Passwords can be openly viewable inside a notepad document, database, spreadsheet, or another digital file. When a password is in plain text, there is no security to keep someone from seeing and using the password. When a password is in plain text format, the password is openly disclosed without any character transformation. You might think about the time when you lifted a keyboard and found that your coworker had recorded their password on a post-it note stuck to the bottom. It is a basic example of a plain text password. Let’s take a step back and discuss the most basic form of recording a password – plain text. We all know the dangers of storing passwords in plain text format. In most environments, passwords are secured using a password hash. Password hashes can impact how vulnerable an organization’s passwords are to an attacker, or in a data leak that may expose hashed passwords. Let’s dive into an overview of password hashing and see why the Active Directory password hash method is crucial in your environment. ![]() Passwords are generally associated with all aspects of securing technology systems. ![]()
