BCrypt Password Hashing Tool is a tool used to generate BCrypt password hash values. It can hash the input string using the BCrypt algorithm and output the hash value.

Features:

1. Enter the string that needs to be hashed in the input box.

2. Select the number of hashing rounds. The higher the number of rounds, the more secure the hash value, but the calculation time will also increase.

3. Click the "Generate Hash" button. The tool will use the BCrypt algorithm to hash the input string and display the hash value in the output box.

Use cases:

1. Password storage: When users register or change their passwords, use the BCrypt Password Hashing Tool to generate hash values and store them in the database to protect the security of user passwords.

2. Data encryption: When sensitive data needs to be encrypted, use the BCrypt Password Hashing Tool to generate hash values and use the hash value as a key to protect the security of the data.

3. Security audit: When conducting security audits, use the BCrypt Password Hashing Tool to generate hash values to check whether the passwords stored in the system are secure.
