Bcrypt Generator

What is bcrypt?

bcrypt is a password hashing function based on the Blowfish cipher. In addition to incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function. The number of iterations can be increased over time to make it slower, making it resistant to brute-force attacks even as computational power increases. Blowfish (b) is the name of the cipher used in the UNIX password system, and crypt is the name of the UNIX password hashing function.

Online Bcrypt Generator Software for Windows, Mac, and Linux

With an intuitive interface, the Online Bcrypt Generator allows you to quickly and easily generate secure passwords.

The Online Bcrypt Generator enables users to generate secure passwords for websites using the popular bcrypt algorithm.

Create Strong Passwords with a Click

The Online Bcrypt Generator is an online password generator that quickly and easily creates strong passwords. It supports bcrypt and scrypt algorithms, as well as SHA1, MD5, and Blowfish hashing methods.

Protect Your Account from Hackers

If you use the same password for multiple accounts, hackers can access them all with just one breach. This means that even if you think you changed your password, it may not be enough. You should ensure that each account has a unique password.

Keep All Your Passwords Secure

To prevent your data from being stolen by hackers, you must store all your passwords securely. Options include using online services like LastPass, 1Password, Dashlane, or Keeper, which allow you to create and securely store strong passwords so you don’t have to remember them.

Password Strength Meter

The Online Bcrypt Generator includes a password strength meter that allows you to see how strong your current password is. This feature will help ensure that your passwords are robust enough to protect your accounts.

Password Manager

Many online Bcrypt generators also include a password manager, allowing you to easily store your passwords in one place. You can use the password manager to create new passwords as well as import existing ones.

Cryptographic Algorithms

You can choose from a variety of cryptographic functions, including the SHA2 and SHA-3 families. On the other hand, the SHA families have a drawback in that they were designed to be fast in computation. The speed at which a cryptographic algorithm computes a hash directly affects password security.

For example, faster computations allow for faster brute-force attacks. Modern CPUs and GPUs can compute millions, if not billions, of SHA-256 hashes per second against a stolen database. Instead of a fast function, we need one that hashes passwords slowly enough to deter attackers. We also want this function to be adaptive so that we can compensate for faster hardware in the future by slowing down the function over time.

The bcrypt Function

bcrypt uses the Blowfish cipher to generate a hash of the input string, returning a string in Modular Crypt format, which is typically found in the Unix shadow password file.

Examples

> bcrypt("hello world")
$2a$10$bFmzZkbkLlLlalKuKB.uK.NS7bSc25dtIgl2f19N6W5p19HjonhEW

bcrypt(string, cost)

The cost argument is optional and defaults to 10 if not specified.

Even if the input string and cost are the same, each call to this function will return a different value because the bcrypt hash includes a randomly generated salt. Consequently, calling this function directly with resource arguments will result in non-comparable hashes. According to the documentation, this function should be used only in preparatory blocks or data resources whose results are used solely in preparatory blocks.

The version prefix of the generated string (e.g., $2a$)

Popular Hashing Algorithms

Several well-known hashing functions are used today:

• Hash-based Message Authentication Code (HMAC): combines shared secret authentication with hashing.
• Message Digest 2 (MD2): byte-oriented, creates a 128-bit hash from a message of arbitrary length, designed for smart cards.
• MD4: similar to MD2, designed specifically for fast software processing.
• MD5: similar to MD4 but slower due to more data manipulation, developed after vulnerabilities in MD4 were identified.
• Secure Hash Algorithm (SHA): modeled after MD4 and proposed by NIST for the Secure Hash Standard (SHS), producing a 160-bit hash.
