Encrypt a JWE with a Password (PBES2)

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPassword, which sets the PBES2 password for a recipient. The example uses PBES2-HS256+A128KW key management with AES-128-GCM content encryption.

local chilkat = require("chilkat")

local jwe = chilkat.Jwe.new()

-- Protected header: PBES2 password-based key management with AES-128-GCM content encryption.
local header = chilkat.JsonObject.new()
header:update_string("alg", "PBES2-HS256+A128KW")
header:update_string("enc", "A128GCM")
local success = jwe:set_protected_header(header)
if not success then
    print(jwe.last_error_text)
    return
end

-- Set the PBES2 password for recipient 0.  The password should come from a secure source rather than
-- being hard-coded.
local password = "myPassword"
success = jwe:set_password(0, password)
if not success then
    print(jwe.last_error_text)
    return
end

local jweCompact = jwe:encrypt("This is the secret content.", "utf-8")
if not jwe.last_method_success then
    print(jwe.last_error_text)
    return
end

print(jweCompact)
