What is bcrypt ? bcrypt is a  password hashing function  designed by  Niels Provos  and David Mazières, based on the  Blowfish  cipher, and presented at  USENIX  in 1999.Besides incorporating a  salt  to protect against  rainbow table  attacks, bcrypt is an adaptive function: over time, the iteration count can be increased to make it slower, so it remains resistant to  brute-force search  attacks even with increasing computation power. What is hashing ?  Hashing is a one way function (well, a mapping). It's irreversible, you apply the secure hash algorithm and you cannot get the original string back. The most you can do is to generate what
