Features:

1. Input plaintext and hash values into the tool.

2. The tool will automatically detect if the hash value is in the correct format for a BCrypt hash value.

3. If the hash value is in the correct format, the tool will use the BCrypt library to verify if the hash value matches the plaintext.

4. The verification result will be displayed in the output area of the tool.

Use cases:

1. Password verification: During the development or testing of an application, developers often need to verify if the password entered by the user matches the hash value stored in the database. BCrypt Verification tool can be used to easily perform this verification.

2. Security auditing: Security auditors can use BCrypt Verification tool to verify if the hash values stored in the database meet security standards.

3. Password reset: When a user forgets their password, an administrator can use BCrypt Verification tool to verify if the new password entered by the user meets security standards.
