Tool description

                  

                    This bcrypt generator creates salted bcrypt hashes (the salt is embedded in the output string). Use it to test
                    password hashing and verification behavior without sending your data to a server.
                  

                


                

                  
How to use

                  
    
                    
  1. Enter a password (use test data, not real production passwords).
    2. 
                    
  2. Choose a cost factor (rounds). Higher rounds are more secure but slower.
    3. 
                    
  3. Click Generate hash to produce a bcrypt string.
    4. 
                    
  4. Paste a bcrypt hash into “Hash to verify” and click Verify.
    5. 
                  

                


                

                  
Why it’s useful

                  
    
                    
  • Quickly generate test bcrypt hashes for development and QA.
    • 
                    
  • Validate that verification matches in your backend (same password → matches hash).
    • 
                    
  • Compare performance across different cost factors.
    • 
                  

                


                

                  
Use cases & interpretation

                  
    
                    
  • Login systems: Store bcrypt hashes, never plaintext passwords.
    • 
                    
  • Cost tuning: Choose the highest rounds your system can tolerate.
    • 
                    
  • Verification: A “match” means the password corresponds to the given hash.
    • 
                  

                


                

                  
FAQs

                  

                    

                      

                        
                      

                      

                        

                          The cost factor controls how expensive hashing is. Each increase makes hashing slower, which helps defend
                          against brute-force attacks.
                        

                      

                    

                    

                      

                        
                      

                      

                        

                          Yes. A unique salt is generated and embedded in the bcrypt output string. You store the full hash and bcrypt
                          uses the embedded salt during verification.
                        

                      

                    

                    

                      

                        
                      

                      

                        

                          bcrypt is designed for password hashing. For general-purpose data integrity or signing, use hashes and HMAC
                          (see the Hash Generator and HMAC Generator tools).
