Frequently Asked Questions
How do I verify a downloaded file?
Choose the file, calculate its SHA-256, SHA-384, or SHA-512 checksum, then paste the trusted checksum supplied by the publisher. A match means the values are identical.
Is the file uploaded for hashing?
No. The file is read and hashed in your browser. The whole file is held in memory while Web Crypto calculates the digest.
Is my input uploaded or stored?
