The result is not a match from the bcrypt-generator.com

What is the reason? Is there a risk of being decrypted?

Hello @JerryCheng1, not sure if I understand you correctly.
Do bcrypt-generator.com and this library yield different hash values for the same input? In that case, it should be noted that the generation of a bcrypt hash is non-deterministic as each hash includes a random salt value that is incorporated into the final output. This protects against attacks via rainbow tables (i.e. lookup tables hash -> preimage).

Hello, @shilch
Yes, the library can yield different hash and hash can be matched by the library. But doing bcrypt-generator.com checker is failed to matched the bcrypt hash was yield by the library. Is the reason that the salt is different?
The library yield one of hash:

$2b$10$nJ3McGQr0jkabP8Zi1V7tu23qrtq347IbtcCNniOJ2nFkcgj9GZdu

The string:

jerry123312

bcrypt-generator.com checker shows: Not a match!

the implementation from OpenBSD is not compatible with the most commonly used algorithms in web services. I replaced the code by the implementation used by project node.bcrypt.
