Frequently Asked Questions
What is a hash generator?
A hash generator creates a unique fixed-length string (hash) from input data using cryptographic algorithms. The same input always produces the same hash, but even tiny changes create completely different hashes. Used for file verification, password storage, data integrity checks, and security purposes.
How do I generate MD5 hash?
Select "Text" or "File", provide your input, choose "MD5" from the algorithm dropdown, and your MD5 hash generates instantly. Note: MD5 is considered cryptographically broken for security purposes. Use SHA-256 or SHA-512 for secure applications.
What's the difference between MD5, SHA-1, SHA-256, and SHA-512?
MD5 (128-bit) and SHA-1 (160-bit) are older, faster, but less secure - use only for checksums. SHA-256 (256-bit) offers strong security and is widely used. SHA-512 (512-bit) provides maximum security with larger hash size. Use SHA-256 or SHA-512 for security-critical applications.
How do I verify file integrity with hash?
Generate a hash of your original file and save it. Later, generate a hash of the file again using the same algorithm. If the hashes match exactly, the file hasn't been modified. Different hashes indicate file corruption or tampering.
Can I generate SHA-256 hash for free?
Yes! Generate unlimited SHA-256 hashes free with Convert-To.co. No registration, no limits. Create SHA-256 hashes from text or files up to 50MB with instant results and complete privacy.
What are hashes used for?
Hashes are used for verifying file downloads, detecting data corruption, storing passwords securely, digital signatures, blockchain transactions, data deduplication, and ensuring data integrity. Essential for cybersecurity, software distribution, and data verification.
Can I hash large files?
Yes! Hash files up to 50MB directly in your browser. For larger files, consider using command-line tools. Our browser-based tool handles most common file sizes instantly without uploads for maximum privacy.
Are my files uploaded to your servers?
No! Your files and text never leave your device. All hash generation happens entirely in your browser using client-side JavaScript. This ensures instant results, maximum privacy and security, and works offline. Your data stays 100% private.
