Hash Generator

Generate MD5 and SHA256 hashes instantly for data integrity and security applications.

⚠️ Security Notice

MD5 is cryptographically broken and should NOT be used for security purposes

SHA256 is secure and suitable for cryptographic applications

• For password hashing, use specialized algorithms like bcrypt, Argon2, or scrypt

• This tool runs entirely in your browser - no data is sent to any server

💡 About Hash Functions

  • Hash functions are one-way functions that convert input data to a fixed-size string
  • Deterministic: Same input always produces the same hash
  • Fixed size: Output length is constant regardless of input size
  • Avalanche effect: Small input changes produce completely different hashes
  • Common uses: Data integrity verification, password storage, digital signatures

🚀 Quick Examples

Input: hello
MD5: 5d41402abc4b2a76b9719d911017c592
SHA256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824
