jc

jc

This is a command line tool which can convert JSON to CBOR and vice versa, with support for Matrix key enums. This utility always produces canonical output for deterministic behaviour.

./jc '{"foo":"bar"}'

Output to 'output' (9 bytes) a163666f6f63626172

Matrix key enum event_id is replaced with byte 0x01.

./jc -out '-' '{"event_id":"$something"}'

?j$something%

Round trip:

./jc -out '-' '{"event_id":"$something", "foo":"bar"}' |
./jc -c2j -out '-' '-'

{"event_id":"$something","foo":"bar"}
