Bcrypt Hash Generator

What is bcrypt?

bcrypt is a password-hashing function based on the Blowfish cipher. In addition to integrating a salt to guard against rainbow table attacks, bcrypt is an adaptive function. The iteration count may be increased overtime to make it slower, making it resistant to brute-force search attempts even as computing power increases. Blowfish, b, is the name of the hashing function used by the UNIX password system, and crypt is the name of the hashing function used by the UNIX password system.

Generate BCrypt Passwords

1. Enter your plain text
2. Select the Cost Factor ( workload / number of rounds)
3. Choose the Hash Format for the output string 
4. Click 'Generate Hash' to compute the hash string

Verfiy BCrypt Passwords

1. Enter the Hashed Bcrypt text
2. Enter the Plain text to be compared
3. Click 'Compare Hash' to validate both strings

Online Bcrypt Generator Software for Windows, Mac & Linux

With its intuitive interface, Online Bcrypt Generator makes generating strong passwords quick and easy. 

The Online Bcrypt Generator allows users to generate secure passwords for websites that use the popular bcrypt algorithm.

Generate Strong Passwords with One Click.

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

Protect Your Account from Hackers.

If you use the same password across multiple accounts, hackers can access them all with just one login. This means that even if you think you’ve changed your password, you haven’t. You need to make sure that every account has a unique password.

Store All Your Passwords Safely.

To avoid having your data stolen by hackers, you should store all your passwords safely. There are several ways to do this. One option is to use an online service such as LastPass, 1Password, Dashlane, or Keeper. These services allow you to generate secure passwords and store them securely, so you don’t have to worry about remembering them.

Password Strength Meter.

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

Password Manager

Many online Bcrypt Generator also includes a password manager so you can easily store your passwords in one place. You can use the password manager to generate new passwords as well as import existing ones.

Cryptographic Algorithms

There are numerous cryptographic functions to choose from, including the SHA2 and SHA-3 families. On the other hand, the SHA families have a design flaw in that they were created to be computationally fast. The speed with which a cryptographic algorithm calculates a hash has an immediate and considerable impact on the password's security.

For example, quicker calculations mean 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 quick function, we need a function that hashes passwords slowly enough to slow down attackers. We also want this function to be adaptive so that we may compensate for faster hardware in the future by slowing down the function over time.

bcrypt Function

bcrypt uses the Blowfish cypher to generate a hash of the given string, returning a string in the Modular Crypt Format, which is typically found in the shadow password file on many Unix systems.

Examples

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

bcrypt(string, cost)

The cost argument is optional and will default to 10 if unspecified.

Even if the given string and cost are the same, each call to this function will return a different value since a bcrypt hash value includes a randomly determined salt. As a result, calling this function directly with resource arguments will result in erroneous diffs. According to the documentation, this function should only be used in provisioner blocks or data resources whose results are exclusively utilised in provisioner blocks.

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

Popular Hash Algorithms

There are several well-known hash functions in use today:

• Hashed Message Authentication Code (HMAC): Combines authentication via a shared secret with hashing.
• Message Digest 2 (MD2): Byte-oriented, produces a 128-bit hash value from an arbitrary-length message, designed for smart cards.
• MD4: Similar to MD2, designed specifically for fast processing in software.
• MD5: Similar to MD4 but slower because the data is manipulated more. Developed after potential weaknesses were reported in MD4.
• Secure Hash Algorithm (SHA): Modeled after MD4 and proposed by NIST for the Secure Hash Standard (SHS), produces a 160-bit hash value.
