JWS with keys

For enhanced security, 2C2P implements JWTs with public/private key pairs to secure information sent to and from merchants. Specifically, JSON Web Signature (JWS) methods are used to generate and process JWTs.

The guide below demonstrates the process.

Before you start

  1. Download the 2C2P Public Key from the 2C2P Merchant Portal: Go to Account > Options > 2C2P Public Keys > JWE
  2. Secure a pair of public and private keys. (For a guide to generating keys, refer here). Please make sure the uploaded public key is in x509 format.
  3. Merchants must then upload the generated public key to the 2C2P Merchant Portal: Log in and go to Account > Options > Merchant Public Keys. Add the public key and set it as default.
