Is it possible to find the SHA256 hash of a webpage? - Ask Ubuntu

how can find sha256 hash of webpage using linux tools (curl, etc.)?

yeah, can use curl , sha256sum in single command, so:

curl www.google.com | sha256sum 

which give:

┌─[✗]─[16:51:49]─[kazwolfe@blackhawk] └──> lib $ curl www.google.com | sha256sum   % total    % received % xferd  average speed   time    time     time  current                                  dload  upload   total   spent    left  speed 100 10221    0 10221    0     0  15500      0 --:--:-- --:--:-- --:--:-- 15509 803d9c7538817dd8b44f0f2b3990ced288413a1b5a6d042d4216170b065e432b  - 

your sha256 sum present down below, long string of hex code gibberish stuff below curl status output.

this works because curl push website's content known stdout, typically gets shown terminal. however, when use pipe symbol (|), redirect stdout of 1 program stdin of another. therefore, sha256sum reading stdin curl command, being used compute sha256 value.
