  • No, there is no way to get the original string without exhaustively trying all possible inputs. This is the entire point of password hashes like bcrypt. – Stephen Touset Sep 18 '18 at 3:12

bcrypt is not an encryption function, it's a password hashing function, relying on Blowfish's key scheduling, not its encryption. Hashing are mathematical one-way functions, meaning there is no* way to reverse the output string to get the input string.

*of course only Siths deal in absolutes and there are a few attacks against hashes. But none of them are "reversing" the hashing, AFAIK.
