  • MD5: Fast but not secure for cryptographic purposes

Why Hash Functions Matter

Hash functions are fundamental to modern cryptography and data security.

Security & Integrity

Hash functions are essential for data integrity verification, password storage, and digital signatures. They ensure your data hasn't been tampered with.

Developer Essential

Every developer needs to understand hashing for secure applications. This tool helps you learn different algorithms and their use cases.

Frequently Asked Questions

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

MD5 is faster but cryptographically broken and vulnerable to collision attacks. SHA-256 is slower but much more secure and recommended for most applications.

When should I use SHA-512?

SHA-512 provides stronger security than SHA-256 and is recommended for high-security applications, though SHA-256 is usually sufficient for most use cases.

Are these hashes reversible?

No, hash functions are one-way. You cannot determine the original input from the hash output. This is what makes them secure for password storage.

Is this tool secure?

Yes! All hashing happens in your browser using the Web Crypto API. No data is sent to our servers, keeping your sensitive information completely private.
