/bin/secretbox

The builtin secretbox of mkfifo.com: a cipher of the crypt backend of rclone, as a tool. The example uses a key of zeros: give your own key, or a sealed word in an envelope. The answer is bytes.

Use it from the web

Its address is https://mkfifo.com//bin/secretbox, with two slashes. Send a POST: the body is the input, and the query gives the words, between & and with percent-encoding. The answer is the output, as the command of a shell writes it. An error gives 422 and the error.

printf '%s' 'hello' | curl --data-binary @- 'https://mkfifo.com//bin/secretbox?-K&0000000000000000000000000000000000000000000000000000000000000000'

The answer (200):

Use it in an envelope

A pipe gives a value to it, as to a FIFO: $body | /bin/secretbox. An egress envelope can send to it, To: /bin/secretbox, and Reply-To gives its answer to a FIFO. These give no words: use the builtin itself for words, as in $body | jq .id.

A builtin here has no FIFO as its home: no code of totp and no sealed key of a FIFO opens in it. Each run counts in the limits of its Request.
