Get the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.GetProtectedHeader, which copies the decoded shared JWE protected header into a JsonObject.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const jwe = try chilkat.Jwe.init();
    defer jwe.deinit();

    // Load the JWE.
    const jwe_compact = "eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMjU2R0NNIn0.<...>.<iv>.<ciphertext>.<tag>";
    jwe.loadJwe(jwe_compact) catch {
        std.debug.print("{s}\n", .{try jwe.getLastErrorText(alloc)});
        return;
    };

    // Copy the decoded shared JWE protected header into a JsonObject.  Only the protected header is
    // returned; it is not merged with the unprotected or per-recipient headers.
    const json = try chilkat.JsonObject.init();
    defer json.deinit();
