Function to encrypt data based on encryption key and iv
Parameters:
- data is each item in inData or outData part of workorder request
as per TCF API 6.1.7 Work Order Data Formats
- encryption_key is the key used to encrypt the data
- iv is an initialization vector if required by the data encryption algorithm.
The default is all zeros.iv must be a unique random number for every
encryption operation.
