What is a cryptographic hash function?

A cryptographic hash function is a mathematical algorithm that converts input data into a fixed-size string of characters. It's designed to be one-way, meaning you can't reverse the hash to get the original data.

What's the difference between MD5, SHA1, and SHA256?

MD5 produces 128-bit hashes but is cryptographically broken. SHA1 produces 160-bit hashes but is also deprecated. SHA256 produces 256-bit hashes and is currently secure. SHA512 produces 512-bit hashes and offers even stronger security.

Can I use this tool to verify file integrity?

Yes! Upload a file to generate its hash, then compare it with the expected hash value. If they match, the file hasn't been corrupted or tampered with.

Are the hashes generated securely?

Yes, all hash generation happens locally in your browser using the CryptoJS library. No data is sent to our servers, ensuring complete privacy and security.
