Bcrypt Hash Generator

This lesson is part of Web Developer Tools · All levels

Summary

Bcrypt is a password hashing algorithm that was deliberately created slow and adaptive. Each hash uses a unique salt, so the same two passwords still produce different hashes. The cost factor determines how heavy the computing is, and the value can be increased as the hardware's capabilities increase.

Key points

Bcrypt is a one-way hash password, not encryption.
Unique salt is made automatically and stored together with hash
Cost factor determines the number of computational rounds
Hash bcrypt generally has a length of 60 characters
Use cost 10-12 and raise it when the server device allows.
