How Hash Functions Work
🔒
MD5 (128-bit)
Fast hash function producing 32-character hex output. Used for file integrity checks.
🛡️
SHA-1 (160-bit)
Secure hash algorithm producing 40-character output. More secure than MD5.
🔐
SHA-256 (256-bit)
Most secure option producing 64-character output. Used in blockchain and security.
Perfect For
•Verifying file integrity and checksums
•Password hashing and security testing
•Digital signatures and certificates
•Blockchain and cryptocurrency applications
•Data validation and verification
•Security research and penetration testing
⚠️ Security Note
This tool generates hashes for educational and testing purposes. SHA-1 and SHA-256 hashes are generated using the Web Crypto API for cryptographic accuracy. MD5 is simulated for demonstration purposes only. For production use, always use established cryptographic libraries and follow security best practices. Never use MD5 for security-critical applications as it's cryptographically broken.
