Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text.
Start typing to see SHA hashes
How it works
Type or paste any text and the hash generator instantly computes MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously. The output updates in real time as you type. All hashing is performed client-side using the Web Crypto API.
Why use this tool?
Used by developers to verify file integrity, store passwords securely, generate checksums, and create digital fingerprints. SHA-256 is the industry standard for secure password hashing and file verification.
Frequently Asked Questions
What is the difference between MD5, SHA-1, and SHA-256?
MD5 (128-bit) is fast but cryptographically broken — don't use it for security. SHA-1 (160-bit) is deprecated and vulnerable. SHA-256 (256-bit) is the current industry standard for secure hashing. Use SHA-256 or SHA-512 for passwords and file integrity.
Can I reverse a hash back to the original text?
No. Hash functions are one-way — designed to be impossible to reverse. If you see your hash in a rainbow table attack lookup, that's why you should always add a salt before hashing passwords.
What is a hash used for?
Password storage (always hashed, never plaintext), file integrity verification (SHA-256 checksums), digital signatures, data deduplication, and generating content fingerprints.
Is this free?
Yes, completely free. All hashing happens in your browser using the Web Crypto API.
