Hash Generator

What is a Hash Generator?

A hash generator creates a fixed-size string (hash) from input data using a mathematical algorithm. Hashes are one-way functions - you cannot reverse them to get the original text.

How to Use This Tool

Enter your text and select the hash algorithm (MD5, SHA1, SHA256, SHA512). Click Generate to create the hash.

Common Hash Algorithms

• MD5: 128-bit, faster but less secure
• SHA1: 160-bit, deprecated for security
• SHA256: 256-bit, secure and widely used
• SHA512: 512-bit, very secure

Common Uses

Hashes verify data integrity, store passwords securely (with salting), and create unique identifiers.

FAQ

Can hashes be decrypted?
No, hashes are one-way. For password storage, use bcrypt or Argon2 instead of simple hashes.
