Hash Generator - Secure Text Hashing Tool
Generate cryptographic hashes from text input using industry-standard algorithms. Our Hash Generator uses the Web Crypto API to provide secure, client-side hashing for data integrity verification, password hashing, and digital signatures.
All processing happens in your browser - your data never leaves your device, ensuring complete privacy and security.
How to Use the Hash Generator
- Enter your text in the input field - any text, password, or data you want to hash
- Select hash algorithms - choose from MD5, SHA-1, SHA-256, SHA-384, or SHA-512
- View results instantly - hashes are generated in real-time with live mode enabled
- Copy hashes - click the copy button to copy any generated hash to your clipboard
Supported Hash Algorithms
SHA-256 (Recommended)
256-bit hash, cryptographically secure, widely used for digital signatures and certificates.
SHA-512 (Maximum Security)
512-bit hash, highest security level, used for critical applications requiring maximum protection.
SHA-384 (High Security)
384-bit hash, excellent security, faster than SHA-512 while maintaining high protection.
SHA-1 (Legacy)
160-bit hash, considered cryptographically broken, not recommended for security applications.

Frequently Asked Questions
What is a hash function?
A hash function is a mathematical algorithm that converts input data of any size into a fixed-size string of characters. The same input always produces the same output, but even a tiny change in input creates a completely different hash.
Which hash algorithm should I use?
For most applications, use SHA-256. It's cryptographically secure and widely supported. Use SHA-512 for maximum security, SHA-384 for high security with better performance, and avoid SHA-1 and MD5 for security applications.
Is my data secure?
Yes! All hashing happens in your browser using the Web Crypto API. Your data never leaves your device and is not transmitted to any server. The tool is completely client-side for maximum privacy.
Can I reverse a hash?
No, hash functions are one-way functions. You cannot reverse a hash to get the original input. This is why they're used for password storage and data integrity verification.
