Password Hash Generator

Multi-algorithm password hash generator: bcrypt, SHA-256, SHA-512, MD5, NTLM. Generate and verify hashes in one tool.

Overview

The Password Hash Generator creates password hashes using multiple algorithms in one unified tool. Support for bcrypt (with adjustable cost), SHA-256, SHA-512 (via Web Crypto API), MD5 (pure JS), and NTLM (MD4 of UTF-16LE). Generate hashes for passwords and verify existing hashes. Perfect for developers and security professionals who need to work with multiple hash formats.
