Bcrypt Password Hash Tool
Bcrypt is a hashing algorithm specifically designed for password storage. It has an adaptive mechanism that can resist brute force attacks brought by increasing computing power by increasing the number of iterations.
Main Features
- Built-in Salt: Bcrypt automatically generates random salt values for each hash, no separate handling needed
- Adjustable Work Factor: Control hash computation complexity by adjusting the work factor (rounds)
- Brute Force Resistant: Deliberately slows down computation to make brute force attacks extremely difficult
- Fixed Length Output: Generates hash values with fixed length of 60 characters
How to Use
Generate Hash
- Enter the password to be hashed in the "Text" input box
- Select appropriate work factor (default is 10, range 0-16)
- System will automatically generate the hash result
Verify Password
- Enter original password in "Compare Text" box
- Enter existing hash value in "Compare Hash" box
- System will automatically verify if password matches
View Hash Information
- Enter a Bcrypt hash value
- System will display the salt value and work factor information for that hash
Security Recommendations
- Recommended to use work factor of 10 or higher to ensure security
- Each increase of 1 in work factor approximately doubles computation time
- Need to balance security and performance in practical applications
- Never store original passwords, only store hash values
