How does the card data encryption/decryption work for the Card Component or Drop-in integration?
When you are using the Card Component or Drop-In integration for processing card transactions, the card data that is entered on the front-end will be directly encrypted in the input fields hosted by Adyen. After you collect the encrypted values from the front-end and submit them in your payment request, our system will decrypt the card data.
If something goes wrong and our system is not able to decrypt the data, you will receive the error 422: Unable to Decrypt Data. To troubleshoot this error, you can check this article.
