About MD5/SHA256 Hash Generator

Calculate MD5 and SHA256 hash values for text and files. Hash functions convert arbitrary-length data into fixed-length strings, widely used for file integrity verification, cryptography, and data validation. MD5 generates 128-bit hash values, SHA-256 generates 256-bit hash values, with the latter being more secure.

Hash Algorithm Comparison

MD5 (128-bit): Fast computation, suitable for non-cryptographic checksums
SHA-256 (256-bit): More secure, recommended for cryptographic applications
File Integrity: Both algorithms can verify file corruption or tampering
Performance: MD5 is faster, SHA-256 is more secure

Frequently Asked Questions

What's the difference between MD5 and SHA-256?

MD5 produces 128-bit hashes and is faster but less secure. SHA-256 produces 256-bit hashes and is more secure but slower. Use SHA-256 for security-critical applications.

How do I verify file integrity with hashes?

Calculate the hash of your original file, then recalculate it later. If the hashes match, the file hasn't changed. Different hashes indicate corruption or modification.

Is MD5 secure for passwords?

No, MD5 is not secure for passwords due to vulnerability to collision attacks. Use SHA-256 or better yet, purpose-built password hashing algorithms like bcrypt or Argon2.

Can I hash large files?

Yes, but very large files (>100MB) may take time to process in your browser. The tool works client-side, so your files never leave your computer.
