The method is designed to retrieve confidential information about a payment card, including the full card number (PAN) and the security code (CVC). This method is required in cases where card details need to be displayed or transmitted for payment transactions.The card_pan and card_cvc parameters contain encrypted data encoded in Base64 format. Encryption is performed using the RSA algorithm with OAEP padding and the partner’s RSA public key. To retrieve the original values, the data must first be Base64-decoded, then processed using the partner’s RSA private key with RSA-OAEP padding.Digest algorithm: SHA-256
