⚠️ 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
