❓ FAQ
What is a hash generator?
A hash generator takes any text or file and produces a fixed-length string using algorithms like MD5, SHA-1, SHA-256, or SHA-512. Hashes are one-way — you cannot reverse them to get the original input.
Is this hash generator safe to use?
Yes. All hashing is done in your browser using the Web Crypto API. No data is ever sent to a server. Verify in your browser's network tab.
What's the difference between MD5, SHA-1, and SHA-256?
MD5 produces 128-bit (32 hex chars), SHA-1 160-bit (40 hex), SHA-256 256-bit (64 hex), SHA-512 512-bit (128 hex). SHA-256/512 are recommended — MD5 and SHA-1 have known collision vulnerabilities.
Can I hash files with this tool?
Yes. Click 📁 Hash File to select any file. It's read entirely in your browser — nothing is uploaded. Great for verifying file integrity.
Why is MD5 considered insecure?
MD5 has known collision attacks. Fine for checksums, but don't use it for passwords or signatures. Use SHA-256 or SHA-512 instead.
Does this work offline?
Yes. All hashing is client-side via Web Crypto API. Save the page and use offline — no server needed.
