Hash Generator FAQ
What is a hash function?+
It converts any input into a fixed-size string; small changes produce completely different outputs.
What is the difference between MD5 and SHA-256?+
MD5 is fast but broken and 128-bit; SHA-256 is 256-bit and considered secure for most applications.
What is HMAC?+
HMAC combines a hash function with a secret key to provide data integrity and authentication.
Is my data safe?+
Yes, all hashing runs in the browser; no text or files are sent to a server.
What is the maximum file size?+
Up to 50 MB; larger files should be hashed with command-line tools.
Can I verify a downloaded file?+
Upload the file, generate its hash, and compare it to the expected checksum using the Verify field.
