Hash Generator

What Is the Hash Generator?

Hash Generator computes cryptographic hash digests across all standard algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512) for text strings, passwords, and file checksums using Web Crypto APIs.

Step-by-Step: Using This Tool

1. Type or paste your input text or upload a file.
2. Select hash algorithm (SHA-256, SHA-512, MD5, SHA-1).
3. View instant real-time hexadecimal hash calculation.
4. Click to copy the hash digest.

Maximize Your Results

• SHA-256 for Security: Standard 256-bit cryptographic hash for password verification, blockchain, and data integrity checks.
• MD5 for File Checksums: Useful for verifying file download integrity against mirror checksums (not recommended for cryptographic security).
• Deterministic & One-Way: The exact same input always produces the same hash, but the original text cannot be reversed from the hash.

Frequently Asked Questions

Which hash should I use?

SHA-256 is the most common modern default for general use; SHA-512 offers more bits of output for extra collision resistance.

Is SHA-1 still safe to use?

SHA-1 is considered cryptographically broken for security-critical purposes like certificates and signatures, though it's included here for compatibility with legacy systems that still expect it. For anything security-sensitive, prefer SHA-256 or higher.

Why use the Web Crypto API instead of a custom hash implementation?

The Web Crypto API is a standardized, browser-native implementation, which is more trustworthy and better tested than a custom JavaScript hash function, while also running efficiently without extra library downloads.

Can I hash a file instead of just text?

This tool hashes text you type or paste in. For hashing entire files, you'd need a dedicated file-hashing tool rather than pasting binary content as text.

Will the same input always produce the same hash?

Yes — SHA hash functions are deterministic, so identical input text will always produce exactly the same hash output every time, across any device or browser.
