Frequently asked questions

Can I hash a large file?

Yes. The file is read locally by your browser. Very large files need enough free memory, since the whole file is loaded to compute the hash.

Is MD5 secure?

No. MD5 and SHA-1 are broken for security purposes. Use them only for checksums and compatibility; prefer SHA-256 or better.
