Hash Generator
Generate secure cryptographic hashes including MD5, SHA-1, and SHA-256. All processing happens in your browser - no data is sent to our servers.
Input Text
How to use: Type or paste text in the input area above, then click "Generate All Hashes" to create all three hash types at once, or use individual buttons for specific hash types. All processing happens locally in your browser for complete privacy.
Hash Types Explained
MD5 (Message Digest 5)
MD5 produces a 128-bit (16-byte) hash value, typically expressed as a 32-character hexadecimal number. It's widely used for integrity verification but is considered cryptographically broken and unsuitable for secure applications.
SHA-1 (Secure Hash Algorithm 1)
SHA-1 produces a 160-bit (20-byte) hash value, typically rendered as a 40-character hexadecimal number. It's also considered cryptographically broken but is still used in some legacy systems and digital signatures.
SHA-256 (Secure Hash Algorithm 256)
SHA-256 produces a 256-bit (32-byte) hash value, rendered as 64 hexadecimal characters. It's part of the SHA-2 family and is currently considered secure for most cryptographic applications.
Use Cases
Hash functions are used for data integrity verification, password storage (with proper salting), digital signatures, blockchain technology, and file verification. Never use MD5 or SHA-1 for security-critical applications.
Privacy & Security
All hash generation happens locally in your browser using JavaScript. Your text never leaves your device, ensuring complete privacy. No data is transmitted to our servers or stored anywhere.
Browser Compatibility
This tool uses the Web Crypto API for SHA-1 and SHA-256, ensuring fast and secure processing. MD5 is implemented in JavaScript for compatibility. Works in all modern browsers.
