How it works
Asymmetric encryption is used to encrypt the sensitive data using a public key from an RSA public/private key pair. The data is then only able to be decrypted by eWAY’s servers using the stored private key. The public key is made available to the merchant for encryption, however the private key is retained by eWAY so that only eWAY is able to decrypt sensitive data.
In this way a merchant can simply encrypt the sensitive data in the client browser, then pass it through their server and make the direct payment with eWAY
