Hash Generator

Generate cryptographic hashes (SHA-1, SHA-256, SHA-384, SHA-512) for text input. Perfect for data integrity verification and security applications.

Text Input

Enter the text you want to generate hashes for

Hash Functions Guide

Common Use Cases

  • • Data integrity verification
  • • Password hashing (with salt)
  • • Digital signatures
  • • Checksums for file verification
  • • Blockchain and cryptocurrency

Security Recommendations

  • • Use SHA-256 or higher for new applications
  • • Avoid SHA-1 for security-critical uses
  • • Add salt when hashing passwords
  • • Consider using dedicated password hashing libraries
  • • Use HMAC for message authentication

Privacy & Security

All hash generation is performed locally in your browser using the Web Crypto API. Your input data is never sent to any external servers, ensuring complete privacy and security.

Frequently Asked Questions

What hash algorithms are supported?
Our hash generator supports popular algorithms including MD5, SHA-1, SHA-256, SHA-512, and others. Each algorithm has different security levels and use cases.
Which hash algorithm should I use?
For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak for security but are still used for file integrity checks and non-security applications.
Can I hash files as well as text?
Currently, our tool focuses on text hashing. For file hashing, you can copy the file content (for text files) or use command-line tools for binary files.
Are hash operations reversible?
No, hash functions are one-way operations. You cannot reverse a hash to get the original data. This is why hashes are used for password storage and data integrity verification.
