Online Bcrypt Hash Generator & Checker

BCrypt is a widely-used cryptographic hashing function designed specifically for securely hashing passwords. A BCrypt hash generator is a tool that generates BCrypt hashes for passwords or other sensitive data.

Encrypt

Encrypt some text. The result shown will be a Bcrypt encrypted hash.

Decrypt

Test your Bcrypt hash against some plaintext, to see if they match.

Here’s how BCrypt works:

  1. Salted Hashing: BCrypt incorporates a technique called “salted hashing,” where a random string called a salt is generated and combined with the password before hashing. This adds an additional layer of security by ensuring that even if two users have the same password, their hashed values will be different due to the unique salt.
  2. Cost Factor: BCrypt allows for the specification of a “cost factor” or “work factor,” denoted as “cost” in the context of BCrypt. This factor determines the computational cost of hashing the password and can be adjusted to make the hashing process slower, thereby increasing its resistance to brute-force attacks. The higher the cost factor, the slower the hashing process.

Using a BCrypt hash generator, you can input a password and generate its corresponding BCrypt hash. This hash can then be stored securely in a database. When a user attempts to log in, the entered password is hashed using the same salt and cost factor, and the resulting hash is compared to the stored hash. If they match, the password is considered valid.

BCrypt is preferred over older hashing algorithms like MD5 or SHA-1 for password storage due to its resistance to brute-force attacks and its ability to adapt to increasing computing power over time. It’s important to note that BCrypt is designed for hashing passwords and should not be used for other types of data hashing, such as cryptographic signatures or message authentication codes.
