FAQ
Frequently Asked Questions
What is a hash?
A hash is a fixed-size fingerprint of data. The same input always produces the same hash, and even a tiny change in input produces a completely different hash.
Is MD5 secure?
MD5 and SHA-1 are considered cryptographically broken and should not be used for security purposes. Use SHA-256 or SHA-512 for security-sensitive applications.
Are my files uploaded?
No. All hashing uses the Web Crypto API directly in your browser. Nothing is sent to any server.
