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).

#include <CkJweW.h>
#include <CkJsonObjectW.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkJweW jwe;

    //  Build the JWE protected header.  The "alg" member names the key-management algorithm and the "enc"
    //  member names the content-encryption algorithm.
    CkJsonObjectW header;
    header.UpdateString(L"alg",L"A256KW");
    header.UpdateString(L"enc",L"A256GCM");

    //  Set the protected header on the JWE.  The protected header is integrity-protected and applies to
    //  all recipients.
    success = jwe.SetProtectedHeader(header);
    if (success == false) {
        wprintf(L"%s\n",jwe.lastErrorText());
        return;
    }

    wprintf(L"Protected header set.\n");
    }
