🔒 Complete Guide to Hash Generator

Generate cryptographic hashes instantly - MD5, SHA-1, SHA-256, SHA-512

A Hash Generator is an essential security tool for creating cryptographic hashes from text or files. Whether you're verifying file integrity, storing passwords securely, or creating checksums, our hash generator provides instant hash generation for multiple algorithms.

🎯 What is a Hash?

A cryptographic hash is a fixed-size string generated from input data using a hash function. Hashes are one-way (cannot be reversed), deterministic (same input = same hash), and unique (different inputs produce different hashes).

Example: "Hello" → SHA-256 → 185f8db32271fe25f561a6fc938b2e264306ec304eda518007d1764826381969

❓ FAQ

What's the difference between hash algorithms?

MD5: Fast but insecure (128-bit). SHA-1: Deprecated (160-bit). SHA-256: Secure, widely used (256-bit). SHA-512: Most secure (512-bit). Use SHA-256 or SHA-512 for security.

Can hashes be reversed?

No! Cryptographic hashes are one-way functions. You cannot reverse a hash to get the original input. This makes them ideal for password storage and data verification.

Why use SHA-256 over MD5?

MD5 is cryptographically broken and vulnerable to collisions. SHA-256 is secure, collision-resistant, and recommended for security applications. Never use MD5 for passwords or security.

Are my files uploaded to a server?

No! All hashing happens locally in your browser. Your files and text never leave your device, ensuring complete privacy and security.
