Start Generating Hashes
Select your hash algorithms and input text or upload a file to generate hashes
Algorithm Selection
Text Input
Maximum file size: 100MB
🔐 Hash Information
MD5: 128-bit hash (32 characters) - Fast but not cryptographically secure
SHA-1: 160-bit hash (40 characters) - Legacy, avoid for security
SHA-256: 256-bit hash (64 characters) - Current standard for security
SHA-512: 512-bit hash (128 characters) - Maximum security
🔒 Privacy: All hashing is performed locally in your browser. Your data never leaves your device.
Ready to Hash
Enter text or select a file to generate cryptographic hashes.
How to Use Hash Generator
- 1
Select Hash Algorithms
Choose which hash algorithms to generate (MD5, SHA-1, SHA-256, SHA-512). You can select multiple algorithms to compare results.
Tip:SHA-256 is recommended for security applications, while MD5 is faster for non-security uses like checksums. - 2
Input Your Data
Enter text directly in the text area or click 'Select File' to hash a file. Files up to 100MB are supported for performance.
Tip:Large files may take longer to process. All processing happens in your browser for complete privacy. - 3
Generate and Copy Hashes
Click 'Generate Hashes' to compute the selected hash values. Use the copy buttons next to each hash to copy individual results.
Tip:Hash values are displayed in hexadecimal format, which is the standard for cryptographic applications.
Security & Privacy
- Hashing runs entirely in your browser; no uploads.
- Secrets and files never leave your device.
- For very large files, hashing time depends on your device.
Features & Benefits

Uses browser's Web Crypto API for secure, standards-compliant hash generation with cryptographic integrity.
Individual Hash Copying
Convenient copy buttons for each hash result, making it easy to use hashes in other applications and workflows.
Privacy-First Processing
100% client-side processing ensures your sensitive data never leaves your browser or gets transmitted to servers.
Instant Results
Real-time hash generation with immediate results as soon as you input data or select algorithms.
Frequently Asked Questions
Is my data secure and private?
Absolutely! All hashing happens entirely in your browser using JavaScript and Web Crypto API. Your data never leaves your device or gets sent to any server.
Which hash algorithm should I use?
For security applications, use SHA-256 or SHA-512. MD5 and SHA-1 are faster but not cryptographically secure. MD5 is fine for checksums and non-security uses.
What file types and sizes are supported?
All file types are supported since hashing works on raw bytes. Files are limited to 100MB for performance reasons. Larger files may cause browser slowdown.
Can I compare hashes from different sources?
Yes! Hash values are deterministic - the same input will always produce the same hash. You can compare hashes generated here with those from other tools or systems.
Why do I get different hash lengths?
Different algorithms produce different output lengths: MD5 (32 chars), SHA-1 (40 chars), SHA-256 (64 chars), SHA-512 (128 chars). This is by design and reflects the security strength.
Are hash functions reversible?
No, hash functions are one-way operations designed to be irreversible. You cannot recover the original input from a hash value - this is a fundamental security feature of cryptographic hashes.
