Compact serialization support for JWE API similar to specifying flag -c in command line

[bineshtj]

I know that calling jose jwe enc -c -I pt.txt -k rsa_pub.jwk from command line gives a compact serialized output. Is it possible to obtain a similar output from the function jose_jwe_enc in jwe.h? How to achieve it if the purpose is not command line execution but simple function calls from a program?

I have the same question!

In the meantime I intend on implementing the compact serialization myself, as it doesn't seem too difficult. I will post back here with my results once I figure it out... But just to be clear I am running this library in Swift, so my implementation will probably only slightly help you write your own in C @bineshtj

I'm also doing the same in the meantime. Well do post a link of what you achieve.

The output is actually done by the JSON library we use, jansson (documentation here: https://jansson.readthedocs.io/en/2.12/).

Functions like jose_jwe_enc will work with json_t* types from jansson, and eventually we print its content with functions like json_dumps or json_dumpf, for instance. These functions take flags to control their representation, and one of them is JSON_COMPACT, which seems to be what you are looking for.

@bineshtj : did the usage of JSON_COMPACT, suggested by @sergio-correia (thanks Sergio) worked for your purpose? Can we close this issue?

[bineshtj]

Yes please. Thanks.
