🔐 PHP password_hash / password_verify Generator

About the PHP password_hash Generator

This tool generates ready-to-use PHP code for hashing and verifying passwords with the native password_hash() and password_verify() functions. Pick an algorithm (bcrypt or Argon2), adjust the cost parameters, and get copy-paste PHP code instantly.

It's built for developers who want to follow PHP's official password-hashing recommendations without memorizing the exact function signature and options array every time.

Key Features

• Two algorithm families: bcrypt (PASSWORD_DEFAULT / PASSWORD_BCRYPT) and Argon2 (PASSWORD_ARGON2I / PASSWORD_ARGON2ID)
• Tunable cost options: bcrypt cost factor, or Argon2 memory_cost / time_cost / threads
• Ready-to-copy code: both the hashing snippet and the matching password_verify() snippet
• Live bcrypt preview: see an actual computed hash for the password you entered, generated entirely in your browser

How to Use the Tool

• Step 1: Type or generate a sample password
• Step 2: Choose an algorithm and adjust its cost options
• Step 3: Click "Generate PHP Code"
• Step 4: Copy the password_hash() and password_verify() snippets into your project

Common Use Cases

• Scaffolding a user registration / login flow in PHP
• Learning the correct password_hash() options array syntax
• Choosing a sensible bcrypt cost or Argon2 memory/time cost for your server
• Migrating legacy MD5/SHA1 password storage to a modern algorithm

Tips & Best Practices

• Prefer PASSWORD_DEFAULT so your app automatically benefits from future algorithm upgrades in PHP
• Never store the plain-text password — only the string returned by password_hash()
• A higher bcrypt cost (or higher Argon2 memory/time cost) is slower but more resistant to brute-force attacks; benchmark on your own server
• The generated hash already embeds the algorithm, cost and salt — you don't need to store them separately

Privacy & Security

Everything runs locally in your browser. The password you type is never uploaded, logged, or sent to any server — including the optional live bcrypt preview, which is computed entirely client-side.
