Set the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetProtectedHeader, which sets the integrity-protected JWE header from a JsonObject. The header specifies the key-management algorithm (alg) and content-encryption algorithm (enc).

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();

    // Build the JWE protected header.  The "alg" member names the key-management algorithm and the "enc"
    // member names the content-encryption algorithm.
    const header = try chilkat.JsonObject.init();
    defer header.deinit();
    header.updateString("alg", "A256KW") catch {};
    header.updateString("enc", "A256GCM") catch {};

    // Set the protected header on the JWE.  The protected header is integrity-protected and applies to
    // all recipients.
    jwe.setProtectedHeader(header) catch {
        std.debug.print("{s}\n", .{try jwe.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("Protected header set.\n", .{});
