Question 1

What hash algorithms does this generator support?

Accepted Answer

This tool generates MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously. SHA algorithms use the browser's native Web Crypto API for maximum performance and security, while MD5 uses a pure JavaScript implementation since it is not available in Web Crypto.

Question 2

Can I hash files without uploading them?

Accepted Answer

Yes. All file hashing happens entirely in your browser using the File API and Web Crypto API. Your files are never uploaded to any server. Simply drag and drop a file or click to browse, and all four hash values are computed locally on your device.

Question 3

What is the difference between MD5, SHA-1, SHA-256, and SHA-512?

Accepted Answer

MD5 produces a 128-bit (32 hex character) hash and is fast but considered cryptographically broken. SHA-1 generates a 160-bit (40 hex character) hash and is also deprecated for security use. SHA-256 outputs a 256-bit (64 hex character) hash and is widely used for data integrity and security. SHA-512 produces a 512-bit (128 hex character) hash and offers the highest security level of the four.
