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).

local chilkat = require("chilkat")

local jwe = chilkat.Jwe.new()

-- Build the JWE protected header.  The "alg" member names the key-management algorithm and the "enc"
-- member names the content-encryption algorithm.
local header = chilkat.JsonObject.new()
header:update_string("alg", "A256KW")
header:update_string("enc", "A256GCM")

-- Set the protected header on the JWE.  The protected header is integrity-protected and applies to
-- all recipients.
local success = jwe:set_protected_header(header)
if not success then
    print(jwe.last_error_text)
    return
end

print("Protected header set.")
