Card Encryption
The card details(card number, expiry month, expiry year, cvv) can be encrypted before passing to Juspay using the asymmetric cryptographic algorithm.
The public key will be shared by Juspay which can be used for encryption.
Encrypt the card details using the shared public key. The sample code snippet is given below.
Prepend "enc-" to the encrypted detail.
Pass the details to Juspay in the transaction call.
Note
Algorithm: RSA/ECB/PKCS1Padding
