    I'm not sure what you are asking that is not clearly answered on Wikipedia page for Bcrypt? If you have a specific question please clarify. – AviD Sep 18 '14 at 11:04

Per Wikipedia's article on bcrypt, the algorithm is a modified version of the key setup process from the Blowfish cypher, repeated thousands of times, using each round's output as the input for the next round.

  • @GrahamHill That describes the blowfish blockcipher, not the bcrypt password hash. While bcrypt is based on blowfish, they're not identical. – CodesInChaos Sep 18 '14 at 13:16
