All hashing happens in your browser. No data is ever uploaded to servers.
Uses native Web Crypto API for maximum performance and security.
From MD5 to SHA3-512, including BLAKE2b and RIPEMD-160.
A hash generator creates a unique fixed-size string (hash) from any input data using cryptographic hash algorithms. Hash functions are one-way operations - you can't reverse a hash back to the original data, making them perfect for password storage, data integrity verification, and digital signatures.
Our hash generator supports 10+ algorithms including MD5, SHA-256, SHA-512, SHA3-256, RIPEMD-160, and BLAKE2b. All processing happens in your browser - your data never leaves your device.
Industry standard 256-bit hash. Used by Bitcoin, SSL certificates, and most modern applications. Highly secure and fast.
Maximum security 512-bit hash. Used in high-security applications and cryptocurrency wallets. Slower but more secure.
Latest SHA-3 family. Used by Ethereum and modern blockchain applications. Quantum-resistant design.
Faster than MD5, more secure than SHA-3. Used in high-performance applications and file integrity verification.
Provided for compatibility only. Not recommended for security purposes. Known vulnerabilities exist - use SHA-256 or higher instead.
Store password hashes instead of plain text. Use SHA-256 or higher with salt for maximum security.
Verify downloaded files haven't been tampered with by comparing hash values with the official checksum.
Create unique fingerprints for documents and code. Essential for blockchain and smart contracts.
Identify duplicate files or content by comparing their hash values instead of entire contents.
MD5 produces a 128-bit hash and has known security vulnerabilities. SHA-256 produces a 256-bit hash and is cryptographically secure with no known practical attacks. Always use SHA-256 or higher for security-critical applications.
No, hash functions are one-way operations. You cannot reverse a hash back to the original data. This is what makes them secure for password storage and data integrity verification.
Yes, 100% safe. All hashing happens in your browser using the Web Crypto API. Your text and files never leave your device - nothing is uploaded to any server.
For most applications, use SHA-256. For maximum security, use SHA-512 or SHA3-512. For legacy system compatibility, MD5 and SHA-1 are available but not recommended for security purposes.
You can hash files up to 100MB. For larger files, consider using command-line tools like openssl or sha256sum on your local machine.
Yes! Click the "Compare Hash" button after generating hashes. Paste any hash to check if it matches one of your generated hashes - perfect for verifying file integrity.
