Frequently asked questions
Is my file uploaded to compute the hash?+
No, hashing happens entirely in your browser using the Web Crypto API.
Which algorithm should I use?+
SHA-256 is the most common choice for verifying file integrity.
Can it hash very large files?+
Yes, though very large files take longer since hashing happens on your device's CPU.
