2.2 Request Encryption (AES)

All business parameters must be encrypted within the data field.

Convert your request parameters into a JSON string.

Encrypt the JSON string using AES algorithm (AES/ECB/PKCS5Padding) with your encryptKey.

Encode the encrypted bytes into a Base64 string. This final string is the value for the data parameter.
