Generate a Public Private Key Pair
You must generate a public-private key pair to upload to the
Unified Checkout
system. The public key is uploaded to the Unified Checkout
platform and
is used to encrypt sensitive information in transit. The private key is used to decrypt
the sensitive payment information on your server. Only the private key can properly
decrypt the payment information.IMPORTANT
You must secure your private decryption key. This key must never be
exposed to any external systems or it will risk the integrity of the secure
channel.
Unified Checkout
accepts only keys that meet these requirements:- Only RSA keys are supported. Elliptical curves are not supported.
- The minimum accepted RSA key size is 2048 bits.
- RSA keys must be in JWK format. More information on JWK format is available here:
- The key ID must be a valid UUID.
