Questions and answers

What is a hash used for?

A hash is a fixed-length fingerprint of data. Changing even one character changes the hash completely, so hashes are used to check that a file has not been altered.

Is a hash the same as encryption?

No. A hash cannot be turned back into the original data.

Why is MD5 not offered?

Browsers do not include MD5 in their built-in cryptography functions. SHA-1 is available for compatibility, but it is no longer considered safe for security uses, so prefer SHA-256 or SHA-512.

Is my file uploaded?

No. The hash is calculated on your device.
