What Bcrypt Generator and Compare does
Bcrypt Generator and Compare is a security tool that hashes plaintext passwords using the bcrypt algorithm with a user-configurable cost factor, producing a secure hash suitable for storing in authentication systems. It also verifies whether a provided plaintext password matches a given stored bcrypt hash. The output includes the full hash string with its cost parameter, allowing developers and administrators to integrate it directly into their security workflows. The tool focuses on the core bcrypt functionality without unnecessary complexity, making it practical for implementation tasks. Users receive a hash they can store and a comparison result that confirms or denies a password match, addressing the fundamental needs of secure password handling.
How to use the IT Tools Bcrypt Generator and Compare
- 1
Enter or paste the plaintext password into the input field labeled 'Password'.
- 2
Adjust the cost factor using the dropdown or slider to set the computational complexity of the hash.
- 3
Click the 'Generate' button to produce the bcrypt hash or the 'Compare' button to test a password against a stored hash.
- 4
View the resulting hash string in the output area, which includes the cost factor, salt, and hashed password.
- 5
If comparing, the result will display whether the entered password matches the stored hash.
Best for
Developers and system administrators who need to quickly generate secure bcrypt hashes or verify password matches without leaving their browser, especially when implementing or testing authentication systems.
Limitations
- No unit switching between hash formats
- Results depend on the selected cost factor affecting generation time
- Interface is functional but minimal with no advanced options
Bcrypt Generator and Compare FAQ
- What does the cost factor mean in bcrypt hashing?
- The cost factor determines the computational work required to generate the hash; a higher number increases security by making the hash slower to compute, which helps resist brute-force attacks.
- Can I use the generated hash directly in my application?
- Yes, the output is a standard bcrypt hash string that includes the cost parameter, salt, and hashed password, ready for storage in user databases.
- How do I verify if a password matches a stored hash?
- Enter the plaintext password in the compare field and the stored hash in the designated area; the tool will return a match or mismatch result based on the bcrypt comparison.
- Is there a limit on password length I can hash?
- The tool processes passwords entered in the input field; very long passwords may be truncated by the browser or the algorithm's internal limits, but typical passwords work within the expected range.
